Uh, so, yeah, 19 00:01:00,030 --> 00:01:02,969 we're going to talk about, uh, Zanuck's, 20 00:01:02,970 --> 00:01:05,098 uh, before I dove into the to 21 00:01:05,099 --> 00:01:07,239 the project, some introductory 22 00:01:07,240 --> 00:01:08,999 tweets about we are and what we do. 23 00:01:09,000 --> 00:01:10,469 I guess you already had some of that 24 00:01:10,470 --> 00:01:12,179 stuff if you were in the beginning of the 25 00:01:12,180 --> 00:01:13,229 previous book. 26 00:01:13,230 --> 00:01:15,659 So why the, uh, 27 00:01:15,660 --> 00:01:16,949 Libya Space Foundation? 28 00:01:16,950 --> 00:01:18,689 It's a foundation profit foundation. 29 00:01:18,690 --> 00:01:20,789 We founded actually to 30 00:01:20,790 --> 00:01:22,139 support schnooks. 31 00:01:22,140 --> 00:01:24,479 But in the process, other projects 32 00:01:24,480 --> 00:01:25,799 were developed outside the, uh, the 33 00:01:25,800 --> 00:01:27,629 foundation. And the mission of the 34 00:01:27,630 --> 00:01:29,819 foundation is to advance and use 35 00:01:29,820 --> 00:01:32,219 open source technologies, uh, in space. 36 00:01:32,220 --> 00:01:34,289 So, uh, trying to 37 00:01:34,290 --> 00:01:36,059 push the boundaries of open source to, 38 00:01:36,060 --> 00:01:38,159 uh, the final frontier, pretty 39 00:01:38,160 --> 00:01:39,160 much, uh, the space. 40 00:01:41,300 --> 00:01:43,549 And we come from the initial police 41 00:01:43,550 --> 00:01:45,679 of Zanuck's, uh, comes from the 42 00:01:45,680 --> 00:01:47,989 Athens hackerspace in Greece, uh, 43 00:01:47,990 --> 00:01:50,089 it's a hackerspace, uh, 44 00:01:50,090 --> 00:01:52,069 as you might expect, with, uh, a lot of 45 00:01:52,070 --> 00:01:54,499 tools and a lot of intelligent 46 00:01:54,500 --> 00:01:56,029 people coming together with various 47 00:01:56,030 --> 00:01:58,129 backgrounds and various skill sets. 48 00:01:58,130 --> 00:02:00,169 We have people that are space 49 00:02:00,170 --> 00:02:02,239 enthusiasts, uh, radio amateurs, 50 00:02:02,240 --> 00:02:05,179 uh, but also coders and developers 51 00:02:05,180 --> 00:02:06,180 and. 52 00:02:07,080 --> 00:02:09,478 As you will see along the dock, sadness 53 00:02:09,479 --> 00:02:11,599 is a project that required many 54 00:02:11,600 --> 00:02:13,519 different skills and many different kinds 55 00:02:13,520 --> 00:02:15,649 of people to work on that show. 56 00:02:15,650 --> 00:02:17,719 The fact that we have this one 57 00:02:17,720 --> 00:02:19,639 place and one physical place to meet 58 00:02:19,640 --> 00:02:22,039 really accelerated the success of 59 00:02:22,040 --> 00:02:23,040 the project. 60 00:02:24,070 --> 00:02:26,289 Which, uh, uh, you may 61 00:02:26,290 --> 00:02:27,909 have heard of that already. 62 00:02:27,910 --> 00:02:30,039 So what we started about three 63 00:02:30,040 --> 00:02:32,319 years ago and 64 00:02:32,320 --> 00:02:34,749 about six months after we started, 65 00:02:34,750 --> 00:02:36,699 we won the Hakodate prize. 66 00:02:36,700 --> 00:02:37,700 Uh. 67 00:02:38,690 --> 00:02:40,789 And that was a big moment for 68 00:02:40,790 --> 00:02:43,009 us because it boosted the project both 69 00:02:43,010 --> 00:02:46,189 in terms of, uh, uh, 70 00:02:46,190 --> 00:02:48,169 financially because it was a financial 71 00:02:48,170 --> 00:02:50,239 price, but also in terms of 72 00:02:50,240 --> 00:02:52,789 community, uh, expanding 73 00:02:52,790 --> 00:02:54,529 because it makes the project very well 74 00:02:54,530 --> 00:02:57,139 known to certain communities, especially, 75 00:02:57,140 --> 00:02:58,159 uh, Radiometer. 76 00:02:58,160 --> 00:03:00,919 So space, uh, 77 00:03:00,920 --> 00:03:01,920 hiker's. 78 00:03:02,780 --> 00:03:04,969 So what's the project, the 79 00:03:04,970 --> 00:03:07,609 initial idea is that this is a, 80 00:03:07,610 --> 00:03:09,889 uh, a picture of, uh, 81 00:03:09,890 --> 00:03:10,910 objects around Earth. 82 00:03:11,960 --> 00:03:13,189 There are thousands of satellites, 83 00:03:13,190 --> 00:03:15,139 especially in the U.S. 84 00:03:15,140 --> 00:03:16,069 orbit. 85 00:03:16,070 --> 00:03:18,359 And as, uh, 86 00:03:18,360 --> 00:03:20,479 Pierrot's explained, the previous, uh, 87 00:03:20,480 --> 00:03:22,759 and I'm sure many of you may 88 00:03:22,760 --> 00:03:25,249 also be involved in various university 89 00:03:25,250 --> 00:03:27,379 or, uh, even hackerspace projects 90 00:03:27,380 --> 00:03:29,869 to build CubeSat and satellites 91 00:03:29,870 --> 00:03:31,189 in general. 92 00:03:31,190 --> 00:03:33,049 So these are the teams that build this 93 00:03:33,050 --> 00:03:34,879 CubeSat, sometimes in the rush of 94 00:03:34,880 --> 00:03:35,809 building their satellites. 95 00:03:35,810 --> 00:03:38,269 Sometimes they don't focus much 96 00:03:38,270 --> 00:03:40,639 on the ground station or the 97 00:03:40,640 --> 00:03:42,209 of the earth side of things. 98 00:03:42,210 --> 00:03:44,269 Uh, so many of the teams, 99 00:03:44,270 --> 00:03:46,519 they launch a satellite in orbit and 100 00:03:46,520 --> 00:03:48,649 that sometimes they don't 101 00:03:48,650 --> 00:03:49,999 even have a ground station to listen to 102 00:03:50,000 --> 00:03:51,439 it or talk to it. 103 00:03:51,440 --> 00:03:52,969 Sometimes they only they have the 104 00:03:52,970 --> 00:03:55,159 resources and the expertize to build one 105 00:03:55,160 --> 00:03:56,929 ground station in the university or in 106 00:03:56,930 --> 00:03:57,949 the in a place. 107 00:03:57,950 --> 00:04:00,019 They they are located and 108 00:04:00,020 --> 00:04:02,149 they just wait for one or 109 00:04:02,150 --> 00:04:04,309 two times per day to listen 110 00:04:04,310 --> 00:04:06,559 to the satellite when the satellite 111 00:04:06,560 --> 00:04:07,560 is above them. 112 00:04:08,330 --> 00:04:10,789 And that's a problem that, uh. 113 00:04:11,970 --> 00:04:14,609 Every team like that faces, 114 00:04:14,610 --> 00:04:16,859 so this is a diagram 115 00:04:16,860 --> 00:04:19,289 of how nano satellites exploded 116 00:04:19,290 --> 00:04:21,028 over the last years. 117 00:04:21,029 --> 00:04:23,079 This is a diagram for CubeSat. 118 00:04:23,080 --> 00:04:25,439 That's another kind of satellite by 119 00:04:25,440 --> 00:04:27,419 pocket, for instance. 120 00:04:27,420 --> 00:04:29,819 So as you can see this, 121 00:04:29,820 --> 00:04:31,439 the trend is that more and more 122 00:04:31,440 --> 00:04:33,419 satellites are put into orbit. 123 00:04:33,420 --> 00:04:35,789 And in most of these cases, nobody 124 00:04:35,790 --> 00:04:37,569 actually communicates with them. 125 00:04:37,570 --> 00:04:39,899 Uh, so it's a 126 00:04:39,900 --> 00:04:41,729 it's pretty much a problem of scale. 127 00:04:41,730 --> 00:04:43,919 And the idea we had back back 128 00:04:43,920 --> 00:04:46,019 then three years ago was 129 00:04:46,020 --> 00:04:47,020 what if we could build 130 00:04:48,240 --> 00:04:49,169 a network? 131 00:04:49,170 --> 00:04:51,209 What if we could build a network of 132 00:04:51,210 --> 00:04:53,399 ground stations and try to solve 133 00:04:53,400 --> 00:04:55,349 this problem of scale in open source 134 00:04:55,350 --> 00:04:57,509 manner and crowdsource model and, 135 00:04:57,510 --> 00:04:59,639 uh, see how this 136 00:04:59,640 --> 00:05:01,709 works and how much the 137 00:05:01,710 --> 00:05:03,839 how how big this network can be and 138 00:05:03,840 --> 00:05:05,209 actually solve this problem. 139 00:05:07,210 --> 00:05:09,579 To give you a quick overview, 140 00:05:09,580 --> 00:05:10,989 what I'm talking about network, we're 141 00:05:10,990 --> 00:05:12,819 talking about something like this on the 142 00:05:12,820 --> 00:05:15,039 left side, it's the users, 143 00:05:15,040 --> 00:05:17,229 which could be people who want 144 00:05:17,230 --> 00:05:19,299 to to communicate 145 00:05:19,300 --> 00:05:21,519 with satellites. That can be anyone 146 00:05:21,520 --> 00:05:23,319 pretty much, but also satellite 147 00:05:23,320 --> 00:05:25,539 operators, operators themselves. 148 00:05:25,540 --> 00:05:27,609 And the network gives 149 00:05:27,610 --> 00:05:31,049 the gives them access to, uh, 150 00:05:31,050 --> 00:05:33,219 a a few ground stations 151 00:05:33,220 --> 00:05:35,109 or a lot of grouchiness around the world 152 00:05:35,110 --> 00:05:37,700 and schedule observations for satellites. 153 00:05:38,890 --> 00:05:40,959 So instead of everyone building its own 154 00:05:40,960 --> 00:05:42,969 ground station in one place, you have a 155 00:05:42,970 --> 00:05:44,979 global network of available ground 156 00:05:44,980 --> 00:05:45,980 stations. 157 00:05:47,190 --> 00:05:49,319 Similar to the to the CubeSat project to 158 00:05:49,320 --> 00:05:51,539 Ubisoft, we also try to find 159 00:05:51,540 --> 00:05:53,669 out what's already there. 160 00:05:53,670 --> 00:05:56,249 So building a 161 00:05:56,250 --> 00:05:57,989 global network ground station is not an 162 00:05:57,990 --> 00:06:00,569 easy job because many, uh, 163 00:06:00,570 --> 00:06:01,519 many moving parts. 164 00:06:01,520 --> 00:06:03,719 So we try to see if there are other 165 00:06:03,720 --> 00:06:05,279 people out there building open ground 166 00:06:05,280 --> 00:06:07,319 stations, if there is software, open 167 00:06:07,320 --> 00:06:09,149 source that we could use either at ground 168 00:06:09,150 --> 00:06:11,399 station or the network site, the things 169 00:06:11,400 --> 00:06:13,949 with the Web services 170 00:06:13,950 --> 00:06:15,319 side of things. 171 00:06:15,320 --> 00:06:17,309 Uh, unfortunately, the one the one many 172 00:06:17,310 --> 00:06:19,649 things. So for most of their components, 173 00:06:19,650 --> 00:06:21,689 we had done the project, uh, we pretty 174 00:06:21,690 --> 00:06:23,220 much read everything from scratch 175 00:06:24,240 --> 00:06:26,099 and we tried to do it in a modular way. 176 00:06:26,100 --> 00:06:28,349 So, uh, you don't 177 00:06:28,350 --> 00:06:30,599 have to use the entire stack of Zanuck's. 178 00:06:30,600 --> 00:06:33,149 If you want to just observe a satellite 179 00:06:33,150 --> 00:06:35,789 you can use you can just build the 180 00:06:35,790 --> 00:06:37,289 ground station. But if you have a ground 181 00:06:37,290 --> 00:06:39,359 station already, you can just plug 182 00:06:39,360 --> 00:06:41,069 it in the network and use the rest of the 183 00:06:41,070 --> 00:06:43,170 Zionist project or the other way around. 184 00:06:46,580 --> 00:06:48,859 So it's a modular project, so 185 00:06:48,860 --> 00:06:51,169 the, uh, 186 00:06:51,170 --> 00:06:53,489 Dave maldita some parts, some 187 00:06:53,490 --> 00:06:55,909 models of this project, so it consists 188 00:06:55,910 --> 00:06:57,559 of the network side of things of the 189 00:06:57,560 --> 00:06:59,509 client, which is a software that runs on 190 00:06:59,510 --> 00:07:01,099 the ground station itself. 191 00:07:01,100 --> 00:07:03,529 There are data on the ground station 192 00:07:03,530 --> 00:07:05,809 antennas, of course, and DEBE, 193 00:07:05,810 --> 00:07:08,119 which is, uh, a Web service 194 00:07:08,120 --> 00:07:10,189 that I will talk in detail 195 00:07:10,190 --> 00:07:11,190 in a bit. 196 00:07:12,960 --> 00:07:15,029 So starting from there, the ground 197 00:07:15,030 --> 00:07:17,099 level, we built a 198 00:07:17,100 --> 00:07:18,570 rotation for a ground station. 199 00:07:19,800 --> 00:07:22,989 In an albatross manner, we everything 200 00:07:22,990 --> 00:07:25,289 on these rotators, of course, 201 00:07:25,290 --> 00:07:27,419 where we try to keep 202 00:07:27,420 --> 00:07:29,819 the cost low, so we used, uh, 203 00:07:29,820 --> 00:07:31,679 we decided in a way that can be half 204 00:07:31,680 --> 00:07:34,079 parts of that 3D printed or parts 205 00:07:34,080 --> 00:07:36,269 that you can easily find in a cheap way, 206 00:07:36,270 --> 00:07:37,739 uh, in a store. 207 00:07:37,740 --> 00:07:40,139 And you can either 208 00:07:40,140 --> 00:07:42,809 build your own, uh, 209 00:07:42,810 --> 00:07:45,069 ground station or just use any data 210 00:07:45,070 --> 00:07:47,639 that's supported by Libyan 211 00:07:47,640 --> 00:07:48,640 city. 212 00:07:51,660 --> 00:07:53,849 Also, one of the things that we wanted to 213 00:07:53,850 --> 00:07:54,959 achieve in order to keep 214 00:07:55,980 --> 00:07:57,479 the cost low, but also make it more 215 00:07:57,480 --> 00:08:00,599 accessible, both in terms of, uh, 216 00:08:00,600 --> 00:08:02,969 cost, but also how to 217 00:08:02,970 --> 00:08:04,439 eat away, how to to make it easier for 218 00:08:04,440 --> 00:08:06,539 you to build a ground station. 219 00:08:06,540 --> 00:08:08,879 We also try to keep the toolchain we use 220 00:08:08,880 --> 00:08:09,779 open source. 221 00:08:09,780 --> 00:08:11,879 So if you try to build a ground 222 00:08:11,880 --> 00:08:13,469 station, you don't have to buy any 223 00:08:13,470 --> 00:08:16,049 expensive software or rely on a 224 00:08:16,050 --> 00:08:17,269 proprietary solution. 225 00:08:18,930 --> 00:08:21,060 So, first of all, we're using a high 226 00:08:22,080 --> 00:08:24,239 tech web, uh, 227 00:08:24,240 --> 00:08:26,549 a web, uh, built by a large boat. 228 00:08:26,550 --> 00:08:28,619 That's, uh, an easy way 229 00:08:28,620 --> 00:08:30,929 to showcase, uh, construction, uh, 230 00:08:30,930 --> 00:08:33,418 steps, manufacturing steps of, uh, 231 00:08:33,419 --> 00:08:35,639 of a hardware device, uh, 232 00:08:35,640 --> 00:08:37,089 in our case, our data. 233 00:08:37,090 --> 00:08:39,359 So if you go to our 234 00:08:39,360 --> 00:08:41,519 instance, you can see pictures 235 00:08:41,520 --> 00:08:44,009 and videos for easily steps how to build 236 00:08:44,010 --> 00:08:45,010 the station. 237 00:08:46,670 --> 00:08:49,009 OK, of course, is open source itself, 238 00:08:49,010 --> 00:08:51,169 we use open source tools 239 00:08:52,520 --> 00:08:54,799 to build and design 240 00:08:54,800 --> 00:08:56,959 the parts of the rotator 241 00:08:56,960 --> 00:08:59,059 freckled keycard. 242 00:09:00,970 --> 00:09:03,130 You got that's for Antenna's. 243 00:09:05,350 --> 00:09:07,489 And that's ah, yeah, of course, we 244 00:09:07,490 --> 00:09:09,399 also like to build our own rotation, so 245 00:09:09,400 --> 00:09:11,649 this is their data controller. 246 00:09:13,490 --> 00:09:14,690 And all of this is, 247 00:09:16,250 --> 00:09:17,629 of course, open source and all of the 248 00:09:17,630 --> 00:09:19,699 schematics and designs are or aren't 249 00:09:19,700 --> 00:09:20,700 repositories. 250 00:09:22,950 --> 00:09:25,219 So this is a photo of a bit 251 00:09:25,220 --> 00:09:27,479 of a ground station later, 252 00:09:27,480 --> 00:09:29,549 but, uh, so you can 253 00:09:29,550 --> 00:09:31,649 see this is actually 254 00:09:31,650 --> 00:09:33,899 a reference platform, but you can use any 255 00:09:33,900 --> 00:09:36,029 different kind of setups, reference 256 00:09:36,030 --> 00:09:37,409 platforms based on that as well. 257 00:09:37,410 --> 00:09:38,999 By 3:00 a.m. 258 00:09:39,000 --> 00:09:40,000 is the hour. 259 00:09:41,590 --> 00:09:43,689 But as I said in the beginning, it's 260 00:09:43,690 --> 00:09:45,259 really modular, so if you don't like 261 00:09:45,260 --> 00:09:47,319 Rasberry, you can use Linux or, 262 00:09:47,320 --> 00:09:49,569 uh, another Abedi device. 263 00:09:49,570 --> 00:09:51,729 So the requirement here is that you 264 00:09:51,730 --> 00:09:54,039 will rely on Python and, uh, 265 00:09:54,040 --> 00:09:56,449 radio, at least for our client 266 00:09:56,450 --> 00:09:57,450 software. 267 00:09:57,890 --> 00:09:59,209 And you can see that it can be really 268 00:09:59,210 --> 00:10:01,369 packed in a in a small box that 269 00:10:01,370 --> 00:10:02,370 you can find easily. 270 00:10:04,610 --> 00:10:06,889 So what we do for the, uh, 271 00:10:06,890 --> 00:10:09,229 for the client software we're using 272 00:10:09,230 --> 00:10:11,359 also here, Obejas, uh, tools 273 00:10:11,360 --> 00:10:13,639 to to build, uh, 274 00:10:13,640 --> 00:10:15,349 uh, rasberry by three imagist. 275 00:10:15,350 --> 00:10:17,509 So we use, uh, the continuous 276 00:10:17,510 --> 00:10:19,579 integration, uh, platform 277 00:10:19,580 --> 00:10:22,489 of GitHub. And we combine that with 278 00:10:22,490 --> 00:10:25,369 Byrant by gennies a project to 279 00:10:25,370 --> 00:10:27,769 help help you kickstart, uh, 280 00:10:27,770 --> 00:10:29,839 Rosebank images, which is 281 00:10:29,840 --> 00:10:31,129 meant for robbery. 282 00:10:31,130 --> 00:10:33,439 And we also use to orchestrate 283 00:10:33,440 --> 00:10:35,299 all the changes we do on top of default 284 00:10:35,300 --> 00:10:36,319 rasberry. 285 00:10:36,320 --> 00:10:39,359 And in the end, what you get is, uh, uh, 286 00:10:39,360 --> 00:10:41,869 uh, Raspberry Pi three emad's 287 00:10:41,870 --> 00:10:44,499 with all the sudden shuffle ready to be, 288 00:10:44,500 --> 00:10:46,700 uh, uh, in the Raspberry Pi three. 289 00:10:48,010 --> 00:10:50,519 Uh, so we we have currently 290 00:10:50,520 --> 00:10:52,619 also nightly bills, but also we 291 00:10:52,620 --> 00:10:54,989 try to cover regular loses in a more 292 00:10:54,990 --> 00:10:55,990 stable fashion. 293 00:10:58,730 --> 00:11:00,289 So these are some photographs from 294 00:11:00,290 --> 00:11:02,269 various ground stations around the world, 295 00:11:02,270 --> 00:11:04,609 so, uh, on the left, 296 00:11:04,610 --> 00:11:07,579 for instance, is that one of the top 297 00:11:07,580 --> 00:11:09,079 of the rooftop of the hackerspace in 298 00:11:09,080 --> 00:11:11,159 Athens, uh, where 299 00:11:11,160 --> 00:11:13,489 Diana Australia, California 300 00:11:13,490 --> 00:11:15,799 on the left and in the middle of downie's 301 00:11:15,800 --> 00:11:18,019 the one in Copenhagen, 302 00:11:18,020 --> 00:11:20,149 as you can see, that one is 303 00:11:20,150 --> 00:11:22,159 without the data, just a turnstile 304 00:11:22,160 --> 00:11:24,379 antenna, which is really good 305 00:11:24,380 --> 00:11:26,329 for NOAA weather satellite. 306 00:11:26,330 --> 00:11:28,399 So you can see a different kind 307 00:11:28,400 --> 00:11:30,709 of ground station with different setups. 308 00:11:30,710 --> 00:11:31,710 So on. 309 00:11:34,300 --> 00:11:35,300 This is a quick 310 00:11:37,060 --> 00:11:39,099 view of the map of globalization around 311 00:11:39,100 --> 00:11:40,359 the world. 312 00:11:40,360 --> 00:11:42,339 I come back to there to this a bit later, 313 00:11:42,340 --> 00:11:44,649 but you can see that, uh, they're 314 00:11:44,650 --> 00:11:46,830 pretty scattered all over the world. 315 00:11:49,210 --> 00:11:51,309 So now let's go 316 00:11:51,310 --> 00:11:53,859 back to the let's go to the clouds 317 00:11:53,860 --> 00:11:56,429 side of things, this is that 318 00:11:56,430 --> 00:11:57,429 sadness to be. 319 00:11:57,430 --> 00:11:59,529 So when we started the project, one of 320 00:11:59,530 --> 00:12:01,599 the problems we had is that we didn't 321 00:12:01,600 --> 00:12:03,759 find any centralized 322 00:12:03,760 --> 00:12:06,129 place for information about satellites. 323 00:12:06,130 --> 00:12:08,199 So the only way that we could 324 00:12:08,200 --> 00:12:09,819 have satellites in order to have 325 00:12:09,820 --> 00:12:11,259 observations about them, to communicate 326 00:12:11,260 --> 00:12:13,499 with them, was to just 327 00:12:13,500 --> 00:12:14,980 dig around blogs and websites, 328 00:12:16,720 --> 00:12:18,879 unfortunately.

And you can schedule each 448 00:16:44,750 --> 00:16:47,419 one of them. You can see some 449 00:16:47,420 --> 00:16:49,489 metadata about their observations so you 450 00:16:49,490 --> 00:16:51,679 can decide if it's a good pass or not, 451 00:16:51,680 --> 00:16:53,749 if it's too low to high, so on. 452 00:16:53,750 --> 00:16:55,849 And you can schedule all 453 00:16:55,850 --> 00:16:57,350 these individual observations. 454 00:16:59,840 --> 00:17:01,999 So this is from an observation 455 00:17:02,000 --> 00:17:04,549 on the left, you can see the metadata 456 00:17:04,550 --> 00:17:06,380 that the network keeps, 457 00:17:07,970 --> 00:17:09,889 which is pretty much the same metadata 458 00:17:09,890 --> 00:17:11,189 that we showed earlier. 459 00:17:11,190 --> 00:17:12,190 Uh. 460 00:17:13,540 --> 00:17:15,279 On the top left, you can see which is the 461 00:17:15,280 --> 00:17:16,929 satellite, which is the observer, which 462 00:17:16,930 --> 00:17:19,179 is the ground station. So on the bottom, 463 00:17:19,180 --> 00:17:21,159 you can see that clearly the orbital data 464 00:17:21,160 --> 00:17:23,229 that was used for that specific satellite 465 00:17:23,230 --> 00:17:24,549 for a specific purpose. 466 00:17:24,550 --> 00:17:26,618 And on the top, right, 467 00:17:26,619 --> 00:17:28,509 you can see that the McGlade audio with a 468 00:17:28,510 --> 00:17:31,240 spectrogram. So you can cover, uh. 469 00:17:32,640 --> 00:17:34,619 The spectrogram helps to have a visual 470 00:17:34,620 --> 00:17:35,640 representation of the audio. 471 00:17:37,090 --> 00:17:39,519 But also, you have that waterfall, 472 00:17:39,520 --> 00:17:41,649 which helps you quickly understand 473 00:17:41,650 --> 00:17:43,549 if the observation actually returned data 474 00:17:43,550 --> 00:17:45,729 or not, and in some cases 475 00:17:45,730 --> 00:17:48,039 we have the modulated 476 00:17:48,040 --> 00:17:50,319 data, if we know, uh, 477 00:17:50,320 --> 00:17:51,819 how do they model for a specific 478 00:17:51,820 --> 00:17:54,699 satellite? So here is a weather 479 00:17:54,700 --> 00:17:57,069 satellite now so we can decode. 480 00:17:57,070 --> 00:17:59,259 We know that we can decode that data back 481 00:17:59,260 --> 00:18:00,260 to any. 482 00:18:02,290 --> 00:18:04,559 So one of the challenges we had with, uh. 483 00:18:05,660 --> 00:18:07,279 With a network is that, as you can 484 00:18:07,280 --> 00:18:09,559 imagine from the from the previous slide, 485 00:18:09,560 --> 00:18:11,779 that each observation has an audio 486 00:18:11,780 --> 00:18:13,759 file, that audio file can be really large 487 00:18:15,320 --> 00:18:17,629 because we try to keep it as high quality 488 00:18:17,630 --> 00:18:20,149 as possible so we can decode it later. 489 00:18:20,150 --> 00:18:22,419 And the problem with that is that 490 00:18:22,420 --> 00:18:24,499 we have got the scale problem because 491 00:18:24,500 --> 00:18:26,479 we needed so much storage in order to 492 00:18:26,480 --> 00:18:27,619 keep all the observations. 493 00:18:27,620 --> 00:18:29,119 We don't delete any observations. 494 00:18:30,350 --> 00:18:32,479 So one thing we recently did is that we 495 00:18:32,480 --> 00:18:35,359 actually utilized Internet Archive, 496 00:18:35,360 --> 00:18:37,759 which you probably already know. 497 00:18:37,760 --> 00:18:39,920 The archive is one of its 498 00:18:41,270 --> 00:18:43,579 mission statement is to actually archive 499 00:18:43,580 --> 00:18:45,799 open data on the Internet. 500 00:18:45,800 --> 00:18:48,709 So we recently, uh, 501 00:18:48,710 --> 00:18:51,289 switched to Guy to keep, uh, 502 00:18:51,290 --> 00:18:53,959 audio files.
