>> Hey friends. Did you know that by the time it reaches Earth, satellites RF transmissions are typically a billion times less powerful than mobile networks, but can still deliver data at broadband speeds? Hrishi Shelar is here to show me how Azure Orbital provides a fully managed ground station as a service, to receive, process, and store data from satellites, today on Azure Friday. [MUSIC]. >> Hey friends, it's Azure Friday. This is awesome. Azure Orbital. We're here with rocket scientist. Hrishi Shelar, how are you? >> Hey, Scott? I'm doing great. How are you? >> I'm pretty freaking good and like no disrespect to your product or your science, but when I read this, I honestly thought that Rob was messing with me. Rob is our producer here on Azure Friday, because I thought it was like an April Fool's thing. That we have a satellite ground station as a Service. That is going to be the most awesome Cloud service that I have ever heard about. >> Yeah, it's pretty amazing and it's that time now where space is going to start coming to the Cloud, and we're going to see even more innovation and new services and it's value add products for everyone. >> How would people get satellite data before? Whether it be a little satellite or a big satellite, how is it done before? What are we basically removing from? Because when you do something as a service, you're removing the boring parts. I assume the rocket scientist wants to get the signal and wants to deal with it, but they don't want to deal with the databases and the tables and learn SQL and stuff. You want to remove the boring parts. >> That's perfect description of what we're trying to do. How it used to be done is you would have to build these very complex, expensive ground stations, which are basically those giant satellite dishes that sometimes you see on top of buildings or by the road. You've seen them on NASA's social accounts. Anyway, people would have to build those themselves. That's a pretty complex process, it takes a lot of money and you have to put them across the world. It's different in each country, dealing with each country has its own problems. This is a common need for a bunch of satellite operators, so we thought we could just off lift that complex process, that arduous task of dealing with all that build out and dealing with regulatory. We take care of that, so you just have to come on and pay per minute. It's basically a pay as you go model. You don't need any upfront dollars or anything. You can just login to Azure, choose Azure Orbital, if you're a satellite constellation operator, choose the passes you want and then you just pay per minute. It's all seamless experience. >> This is the most extraordinary example of hiding complexity with layers of abstraction that I can't even conceive of. Because I used to work on a website called 800.com before Amazon, 800.com, we tilt DVDs and the boss would say, "Can you scale out the system?" Then he goes home, and then he come back on Monday and the system was scaled out. He's like, "Oh, it's amazing." Well all weekend long we were racking servers. In his mind, he moves the slider bar and like the thing scales, but it's us racking servers. Now with Azure, we've hidden everything behind a slider bar. We've got checkboxes for stuff. There are still physical machines, and there are still people who rack machines and there are still people who set up these giant warehouses and data centers, but the business person doesn't care because that's not their business. You're really freeing the satellite consolidators to do their business and not think about the buying the land, to put the dishes on, and all of the details. >> That's spot on. If you're satellite operator or let's say you're satellites space start-up, which is crazy to think of that you'd never have. You've had startups for a decade now on app industry or online startups, but rocket launch costs have just gone down drastically. I'm sure people are aware of SpaceX and other companies but their innovation means that there can be things like satellite space constellation startups. Now, we make it very easy for these guys to focus on the business because they have that slider approach. If they start off with one spacecraft, they actually get access to an entire network of ground stations through orbital, which is something they classically couldn't do. Then as they scale up, they just request more time, more passes, more minutes, and then it's all available on orbital. They are perfectly matched in their business needs and expenditure not having to like you mentioned, working about building out those racks themselves or building out those ground stations. We make it so that they can focus on their business and in the product that they probably want to deliver, and this stuff is just abstracted for them. >> That is a wonderful example of what the Cloud really is, as you focus on your business and we'll worry about the technical stuff. Fantastic. Can you show me a demo. Do we have a satellite there in your living room. What are we doing? >> What we have here is a prerecorded pass of a public satellite known as NASA Aqua which is a weather satellite that NASA operates. The cool thing about this spacecraft is that it's continuously transmitting for anyone to receive and get the data from to look at. It is in a frequency band that you and I don't necessarily always have access to in a gigahertz but what this satellite allows us to do is show the world how the system works. You would be able to also login to the portal, and if you wanted to get familiar, you could do a similar exercise right here. You could schedule of past with Aqua and watch the signals come down and you can get familiar with it. We have a pre-recorded pass here, and the reason it's prerecorded is because it's quite the feet to do a recording and a satellite pass in onetime. We've just made it simple for today. >> Sure. >> I can walk you through what the system looks like here. >> Sure, I'd love to see that. Before we start though, how fast are these things going? If we were theoretically to try do something like this live, is it like okay, we've got six minutes as it goes near arc length of where my visible sky is or how does that work? >> Great question. These things are going around Earth. NASA Aqua is going around Earth every 90 minutes but you have to remember the Earth is also rotating. What that means is, for this type of orbit, the passes are either at 2:00 AM or late in the afternoon, and either very short in time, so we have to be right on the nose to time these two perfectly. Even between days when they occur, they can go back and forth. >> Does Azure Orbital make that easier for me that I don't necessarily have to be there to do the analysis? I don't have to do it live, right? >> Absolutely. Azure Orbital is just not, it's just ground stations, but there are mission planning tools that are available. We will do the orbital propagations for you, and when you come onto the portal, as you will see here in a few minutes, you just say, this is my spacecraft, this is its orbit. Tell me what's going to be there in the next 10 days, and you can just click, click, click, choose them, and it will just run, when those passes occur, the system will know satellites is coming ahead, tell those antennas to go, do and point up, and then you will start getting your data. We try to make it as easy as possible for the operators to understanding that these things can be a complex scheduling problem. >> I love it. This would have made the movie contacts goes so much differently than it actually did. Let's see some satellites. >> I've pulled up my screen. Can you see it? >> Yeah, looks great. >> Awesome. When you get into the portal and you navigate to Azure Orbital, you'll see these three big steps here, and we try to make it as simple as possible. These are the three steps that you need to do to get your passes. Starts off with registering your spacecraft, where you enter details such as the frequencies that are being used, the orbit, and an ID. Then you move on to the contact profile, which describes what you're looking for. The antenna requirements and some other parameters that just help us define how we coordinate that and conduct that pass. Then once you have those two, step three is where you tie them both together and then start making your reservations. >> It is amazing things that you're making. You're talking to a spacecraft as easy as registering Raspberry Pi for like an IoT portal. >> Yeah, and that's a great observation because thinking of spacecrafts, and this whole mechanics of communicating with these devices far away is very much like the IoT world. There's a lot of similarities. >> The other thing that makes me wonder, and this is probably for another whole show we should talk about, is the idea that satellites, I assume right now are primarily sensor devices that then spit back the raw data and then the work happens over here. They're not exactly clever. Their job is to stay up there, think about power, think about sensing, and then bring the data back but it's the new Edge. The Edge network could theoretically be out there, and you're managing an Edge network device regardless of whether it's RF, or Ethernet or whatever. There could be additional processing up there. This could change the design of satellites themselves. They could become smarter, they could become different if they know the context or larger Cloud contexts in which they exist. >> Scott, you should come and join Orbital I think. You're very acute in these observations. Absolutely. As satellites become cheaper, just like launch vehicles, as they get more powerful because the computer industry is so innovative right now. There's endless possibilities, and those workloads can happen on the Cloud, on the satellite. We are the bridge between both those worlds. Azure, you can chain services. There's so many different ways to think about how you build out a solution. It's very exciting. >> This is so cool. >> This is just a new service. What you described, it's in the roadmap. We will definitely get to a scenario like that. >> I have to say this. I used to think the coolest thing that I've ever seen before was my Raspberry Pi, Kubernetes cluster but now I need like a mini satellite. What's the size of a satellite? How do I get one of these in my house? There are actually smaller than you'd think, I've seen satellites they are about like that. >> Yeah, I've worked on satellites, this big to as big as a mini fridge. They can get as big as a school bus truck. It's not larger, sometimes. >> That's awesome. Sorry to go off on tangents. Let's go back to on-boarding a spacecraft. >> I'm going to click "Play" here and then we'll see us tap through a couple of these options. Described a spacecraft and then those details putting in the contact profile details, and then you're ready to schedule. We've already created a contact profile here. I'm going to pause for Aqua, which is that spacecraft we just described. Here we have some simple requirements that describe what's your minimum time that you need for a pass. We have here one minute. That format is just the Azure time format. Some other requirements like elevation is provided, and audio track, and X band but these are all very fine details that have to do with the off satellite communications. We've already populated a contact profile here, for Aqua. [inaudible] , we've done the same for the spacecraft. You'll have a spacecraft object and we have the NORAD ID, which is awaited to track objects in space. Then these two items here, TLE, you'll see there's a TLE line. These are just ways the industry used to describe the orbit. It's pretty cool, the whole science behind it but with these two lines, you get a full description of the spacecraft orbit. Also, you can use this to propagate where that spacecraft might be a day from now, a couple of days a week from now. This is specifically what enables us to know where the spacecraft is, and then marry that with where the ground station is in time so we can reserve your past. >> I see. If I may try to understand this, when I as a lay person, see a TV show where there's like a number comma, a number and I go, "Oh hey, its latitude and longitude." That's a pair that describes a place on the planet. A TLE that two line element describes everything that one needs to know to describe where the satellite is, how it moves, its orientation, its attitude, its behavior. It's multi-dimensional, encoded into like one thing where you can copy this guid, this two line element and say, "Yeah, that's everything you need to know about the satellite." Is that correct? >> Yeah, that's absolutely correct. It's exactly like latitude, longitude, with some extra spice for direction, velocity and inclination, all sorts of fun things. But that's a full description of a spacecraft orbit, just like coordinates fully describe where you are on Earth. >> Sweet. It's so interesting to see that it's 2021. Then we're looking at like a 60-year-old data format. But it was really well-designed and thoughtful and it's the one everyone agrees upon. That's how we talk about satellites. It works. >> This is a very common representation. It's industry standard, even globally accepted as a way to do this and describe orbits. You come in here and you can create your spacecraft object. You enter these items. Then those last field authorization status. There is a final check that we do to make sure that the spacecraft that you want to talk to is actually a registered spacecraft, or is as authorized by the FCC for these type of transmissions. We do have to make this check just to be sure. We're not going to do anything in advertent. >> Cool. >> Moving on. Tabbing over to the contact page, you see that there's nothing there. Let's go ahead and schedule one. We come in here, you choose the contact profile. The ground station is describing the location that you want to do the scheduling on, so we have multiple regions. West US 2 is the Pacific Northwest. You put in some start times and end times, and this is the time window and what you want to do your reservations. >> Does this imply that there is a satellite dish on top of an Azure Datacenter? Because the ground station is the processing station to do the ingress of the data. But there is some, now where does the actual antenna? Where's the actual like capturing of the thing? Where's the dish? >> Yeah, that's a great question. We have installed these antenna dishes at our datacenters. The exact locations of the datacenters are once you're onboarded in the system and we know who you are we can absolutely share those, and there's also maybe after this demo we talk about it. We have partner networks too which is what makes this extremely powerful is that this interface enables you to get access to Microsoft's own dishes, but also a very wide, vast globally available partner network. You can choose these regions and in this drop-down here. >> Awesome. >> I've entered some time windows and the system comes back with these Least Available passes. It took the TLE, it took my contact profile, it took my regional preference and my time window and said, "Hey, looks like in this upcoming days, you have these passes available for that region." It'll tell you how long that pass is, which is just part of the orbital geometry. Maximum elevation is used as a figure of merit for the satellite pass. All it does is describe how high in the sky the satellite is passing over. We're going to go ahead and choose one on the second line here, which is a eight minute 50 seconds pass at 15 degrees. >> This is awesome. This is just like picking an Uber for a satellite and it's like, you know, and the second one might get a little longer, but that's the better choice for me. Like you gave it your destination, you gave it your TLE, it gave you an option of all the different drivers that are available and then you make an educated decision. >> Yeah, that's great analogy, exactly. If you need a faster driver that needs to come sooner, you could do that or if you need a driver that will, that maybe has this passes longer time, you could do that. We choose this one over here and we schedule it. It's going to create this contact pass for you. Once it's done, you can click on it and then we go back to the spacecraft's page and, on the Contacts tab, we'll see that our thing is scheduled, and then here you can get additional details for when the actual start time is and when the actual end time is. >> In the movies when you are looking for something, they move the giant satellite and it's like looking over there. Can I and another person look at two different satellites at the same time, or is it like synchronous that we all have to get in line for our time on the satellite dish? >> Yeah, great question. The dishes are directional. It's a giant parabolic dish and it's focus is vary in a particular point in the sky as it moves. What we have is we have multiple dishes at the sites to solve this. They provide redundancy to each other, but also the ability to handle, let's say, multiple reservations were being requested for a site. That's how we solve that and then on top of the ones that we install, the partner networks further provide this scheduling optimization. >> That's cool. There's a lot of different options and then I'm not going to be fighting for time unless this becomes wildly popular and everyone is like checking out satellites on Azure Orbital all day long, every day. >> We do hope that the goal is to get so much demand that we're just putting these dishes everywhere. >> That would be an awesome problem to have. You Skechers reservations start and end time? >> We're going to keep plan and we'll cut forward to the actual pass here, and let me pause the screen and describe what's going on. This is at one of our partner sites, USCI in booster. They have 7.6 meter dish setup here and USCI stands for US Electrodynamics Incorporated. For those curious, we have a live webcam view here and these four tabs are a behind the scenes peak that I'd like to show you just to also talk a little bit about cool technology that we're adding on top of this. This is a whole another layer that we didn't even touch, but now we will get to see what it is. What's going to happen is we're just coasting, waiting for the satellite to come overhead. It looks like a pretty good day in Eastern Washington. >> I'm noticing though, forgive my ignorance, but you said at the beginning of the conversation that this was going to be around eight gigahertz and the numbers that I'm seeing on the screen, like 600 megahertz and one gigahertz aren't the same area. >> That's a great observation. The antenna is not only just to RF focusing device, there are some components in the antenna located right at the feet or are behind the parabolic dish. What they do is they take your high frequency and then we mean really super highlight, like extremely high, eight gigahertz is extremely high and using some RF magic, it just moves it down couple of notches. >> It's like when we look at x-rays or we look at heat stuff for the predator sees infrared. We're seeing it in red and green and blue because we've taken something that isn't visible and shifted it down into a spectrum by which it is visible. In this case, we've modified how one perceives it, so you're making it more accessibly perceive. >> Right. That's exactly what's happening here and what we're seeing here, maybe let's just go into the technology here real quick. What this screen is showing is a view of the front end and another thing that Azure Orbital does differently is we virtualized the RF. That's like a big buzzword but what that really is, is let's say in the classical way of doing things, you'd have a hardware Modem. So you'd buy this big box and you'd put it near the ground station, and it would take in the RF and outcome bits. Well, the problem with that boxes, it only does one type of RF signal scheme. If you wanted to talk to multiple spacecrafts, you'd have to have maybe a unique box for each spacecraft and that doesn't scale, because we want to be able to add more customers, more different types of spacecraft's on very fast-paced, ad hoc way. What we do here is we virtualize that modem and it's extremely cool cutting edge technology in the satellite communication industry right now. We take the signal, which slices up really fast, and we record that signal. It's called digitization so we digitize that signal and that is piped to the Cloud. In the Cloud we've partnered with these leading software modem companies cradles and emergent, and we instantiate that hardware box virtually and we feed in the samples, and it does the RF to bits. But now, because this is software modem, we're very flexible in the type of RF signals we can accommodate. We've decoupled this unique problem and are solving it in cool ways. >> That sounds as revolutionary to the RF and the satellite communications industry as software-based networking was to Azure in the network itself. I was using that example where I was racking servers. I was literally plugging Ethernet in and I don't do that anymore. It's just not a thing. Because it's been abstracted away completely. The flexibility that offers you the idea that you have all these signals coming in across the spectrum and you just turn it into bits is overly simplistic, so you've sliced it further back. You digitize the entire thing and then wait until the last minute to turn it into bits because you don't want to lose any fidelity at all. >> Exactly, and that's what makes it so powerful is because you get access to worldwide network of dishes. You can pipe in from anywhere and then you can process from anywhere too and exactly how you want to process. This is something you couldn't do if you were rolling out your own ground station with your own hardware based modems. You just didn't have that flex. >> That's amazing. All right. >> All right. Let's walk through this. We're waiting for the satellite to come up. We'll go through these other tabs and these two systems here. This Data Defender product is what pipes those RF streams from the ground station to the Cloud. There is one at the actual site and there's one in the Cloud, as well as two Data Defender tabs. Then in the Cloud, what we see here is an example of what that software modem looks like. This one's [inaudible] and it has all the parameters that you would expect for a hardware modem. Except we've just instantiated this in basically real-time as needed in the exact scheme we want. Once the satellite comes over, we'll see some data flowing. I'm going to play. We've got this bucket here which is going to output. That's where the data will be output. The satellites come over the horizon. We're seeing that the digitizers seeing that signal come up. The Data Defenders are now streaming that digitized signal into the Cloud. It's doing that slicing really fast and we're getting that high fidelity analog to digital signal going straight to the Cloud. >> That is 300 plus megabits. That is a lot of information. It's a flood of information. >> Right. Three hundred megabits is the RF signal. Right now it's 300 megabits. It can scale up too many Gbps depending on the application. >> I always wondered how my direct TV was able to surf so many channels. >> Oh yeah. In this modem here, we see that we're looking at the signal and this right from the spacecraft and it's all software-based and the spectrum plot looks good. We're looking at the carrier lock stay, it's all locked. This is the signal to noise ratio, which is looking really good. >> There's no one else in that space interfering? There's no one with an AM or FM radio, you can hear two channels at once or someone can leak into your signal space? >> Yeah. Great question. No, because the dish is directional and if it were to happen, Azure, we'll take a look into what the interference is. There's a bunch of work that we do for pre-coordination of where these dishes go to ensure that it's a quiet environment for the frequencies that we expect people to operate in. >> Amazing. >> That's just part of the service. >> That's an example of a problem that I would have had to worry about and now that's not my business. That's so awesome. >> Great. We work with the regulatory folks. We make sure the data centers themselves are pretty frequency clean. Interference is the last problem that we want. Great question. Yeah, so just tabbing through the different items in the software modem. These all just represent parameters typically associated with satellite communications and everything here is looking really good. Everything is in lock. We're getting the data from the spacecraft and this is typically what we would expect a majority of the satellite passes to look like. You go through the three-step process, you schedule a pass. At time of pass in waiting for the satellite to come over the horizon. Let me jump forward to the end. Yeah, we wait for the satellite to come onto the horizon, and then the data starts coming in. It's getting digitized, it's getting reliably sent to the Cloud, it's getting processed, and this a good state for eight minutes. Nothing's going wrong. No drastic changes. This is the perfect satellite pass. In this demo here we've cut to the end. Since the past was eight minutes long, we just showed the first minute and we've cut to the end. We're taking the output of this modem and then there's a script in the background that's processing this awkward data which you could download from NASA's aqua website. Since it's a public spacecraft, they let you use these tools for free. We'll see here that our script is able to pull out these files here, which are the image files, but also some scientific data files. We're going to open one. Let's see if I can just skip ahead to when it gets downloaded. We've downloaded one and then we're using, I guess, some pretty funky tools to look at this data because it's unformatted, unpolished data. It's just raw of the sensor. It's not just like JPEG that comes down. It's a very high volume, very raw formatted, just like when you capture on a DSLR, maybe it's raw pixels, but imagine that 10 fold, the complexity. We're using this tool to take a look at the image here and we'll see a pop-up on the screen real quick. >> Does every satellite agree? Like the two-line element that you showed me is effectively a packed data structure in the classic C data structure where it's like these two bytes mean this and these eight bits mean that and then you just basically have binary data and you chop it up because someone decided arbitrarily that these eight bytes mean that. Does every satellite get to decide how their bits are or do they just use a standard format? >> Wow. Always impressed with your questions. It really depends on, let me show you this image first because it's on-screen. Here's the image on-screen. We're looking at some clouds over the ocean it looks like. This was just pulled in real-time as you saw in this demo from Aqua, all within the span of 10 minutes during which we did this recording. Getting back to your question, is there a standard format? Honestly, one wishes for a standard format, but that's not the case. The satellites are very different depending on who builds them, which country is building them, which company is building them from who the satellite builder was, you can make, build and procure spacecrafts now. But the cool thing is, because we've virtualized everything offered in the Cloud, it's so flexible that you're not limited now by those hardware platforms that you might have been limited in the past. You can build the service however you want. You have the selection of dishes upfront. You have the selection of software modems, ability to run them in any region, ability to chain that with any Azure service. You have your own product and you have your own satellite. You can own the chain end-to-end. >> This is going to sound totally obvious because I'm sure that the audience who's sticking with us has figured this out already, but you just blew my mind because when you said chain with other Azure services, that's where I just felt like, "Oh, duh, I can bring it into any Azure service queues, storage, processing, batch, flows". Once it's in, it's my data and I can go bananas. >> Yeah. I've also just pulled up on the screen here, this is online. >> This is a Data Factory. >> Yeah. If you go to docs.Microsoft.com, put in Azure Orbital, you would be able to see this page here and this graphic I just pulled out that describes exactly what we're talking about. The items in dark blue is what we handle, the hard stuff, the things that are abstracted, made easier, made seamless for you, and then items in light blue are what you can focus on. So you can focus really on security for your products or your spacecraft. Then, there's data processing pipeline, honestly, this is the small blue box, doesn't do it justice. That is, as expansive as all of the Azure's services, which is AI, ML, Databases, IoT, anything like literally the myriad of options. >> You're right. The Cloud is your oyster. We've done dozens of videos on the power of Data Factory and the processing pipeline. The amount of data that can come in is immense. The amount of chewing on that data is immense. The marriage of satellite ground services as a service and Azure itself is genius. I'm gushing. I know I work here, but all of the layers of abstraction from the early satellites in the '50s, '60s, and now, and the Cloud and layers of abstraction in software engineering and data structures and science and RF, it's all coming together into this lovely solution. People in this industry must be absolutely freaking thrilled about this. >> Yeah, there's a ton of interest and I don't think we've even gone past the tip of the iceberg. Honestly, we're just at the beginning of all this. People in the past built their own ground stations, built their own data processing pipelines on-prem. In the past few years, they're moving the data processing into the Cloud. Now, ground stations are going into the Cloud. Now, what comes next is we just want to support all these crazy scenarios, these next-gen spacecraft systems. What this means is that end-to-end solutions just become easier, faster, more valuable, and we can extract more value out of the spacecraft. Everyone gains to benefit. >> Awesome. This is in preview. Folks that are interested can go up to the Azure Orbital overviews or they can get in contact with your team, express their needs, get involved. What can enthusiasts do? Because not everyone who's watching this show has a satellite that they want to listen to. I would suggest that they look at Software-defined networking and try to listen to the local radio station and get some RF signals themselves just to be an enthusiast. But what can I do? Because I don't have a satellite? >> Software-defined networking is a great analogy for this. There are these hobby-grade software-defined radios that you can get now. >> I just have a little one. It was $19. >> Right. It just makes it accessible for everyone. Yeah, I think you can get that $20 system and you plug it into your computer and you can listen to FM radio. That's basically what we're doing on a massive scale. Definitely if you're interested, check those out. There's this thing called USRPs, that's just a step above the $20 dongle. There's an open-source platform called GNU Radio, which is incredibly powerful. I've used that on personal projects in the past many times. Right now, we are in private preview, so we're working with some customers to show them how this system works. We'll go into public preview later this year, which means it would be open for potentially more hobbyists to come on and get their feet with this advanced technology. >> This is very exciting. This has been the longest and most awesome episode of Azure Friday we've ever had. I really appreciate you. I really appreciate you hanging out with me. >> That's very high phrased. >> No, I'm telling you. It's like three times longer than ever and we've never had so much space and so much awesomeness and satellites and everything. This has been super amazing and actually, it's my birthday, so it's really my best birthday gift ever. >> Happy birthday. I'm glad we're able to have such an awesome talk. >> All right. I am just gushing about the excitement about what's happening right now in space and in the Cloud. We're learning all about Azure Orbital today on Azure Friday. >> Hey, thanks for watching this episode of Azure Friday. Now I need you to like it, comment on it, tell your friends, retweet it, watch more Azure Friday. [MUSIC].
