1 00:00:00,000 --> 00:00:00,000 2 00:00:06,400 --> 00:00:08,750 So it's , it's an interesting name . 3 00:00:08,760 --> 00:00:10,871 The company we're working with that's 4 00:00:10,871 --> 00:00:12,816 creating a system we're testing is 5 00:00:12,816 --> 00:00:14,982 called Star NAV . We change the S to A 6 00:00:14,982 --> 00:00:17,379 five because we're testing five GPS 7 00:00:17,389 --> 00:00:19,389 signal . If you look at it to begin 8 00:00:19,389 --> 00:00:21,659 with , they can either all be off or 9 00:00:21,750 --> 00:00:24,219 that one can be on . So the project is 10 00:00:24,639 --> 00:00:28,370 testing A L five and GPS and 11 00:00:28,379 --> 00:00:31,940 Galileo E five A receiver 12 00:00:31,950 --> 00:00:34,709 using some existing hardware on , in 13 00:00:34,720 --> 00:00:38,549 this case , a 238 . Um So we're 14 00:00:38,560 --> 00:00:41,470 seeing can we can this implementation 15 00:00:41,479 --> 00:00:44,229 of the receiver work and then how can , 16 00:00:44,290 --> 00:00:47,950 how five and Galeo E five A be used to 17 00:00:47,959 --> 00:00:51,099 improve the navigation for systems that 18 00:00:51,110 --> 00:00:53,054 already have some of this hardware 19 00:00:53,054 --> 00:00:55,166 already on the aircraft , tested your 20 00:00:55,166 --> 00:00:57,277 lights , that's important , but we'll 21 00:00:57,277 --> 00:00:59,388 come back to it later . So GPS L five 22 00:00:59,388 --> 00:01:01,277 is the newest signal that's being 23 00:01:01,277 --> 00:01:03,332 deployed on the GPS satellites . And 24 00:01:03,332 --> 00:01:05,499 what star now has been working on is a 25 00:01:05,499 --> 00:01:08,209 piece of equipment that allows jets to 26 00:01:08,220 --> 00:01:10,959 be able to use those signals and it 27 00:01:10,970 --> 00:01:13,137 allows them to do it without equipping 28 00:01:13,137 --> 00:01:15,220 the jets with new hardware . We're 29 00:01:15,230 --> 00:01:17,286 basically just doing a little bit of 30 00:01:17,286 --> 00:01:19,508 regression testing and making sure that 31 00:01:19,508 --> 00:01:21,563 the capabilities of the aircraft are 32 00:01:21,563 --> 00:01:23,397 still unaffected by our system . 33 00:01:27,199 --> 00:01:30,120 The T P S students bought and painted a 34 00:01:30,129 --> 00:01:33,610 bus to look like the X 62 35 00:01:33,620 --> 00:01:36,830 vista . We're using it for our test as 36 00:01:36,839 --> 00:01:38,940 a GPS space station . So we're 37 00:01:38,949 --> 00:01:42,190 recording GPS on the 2 38 and also on 38 00:01:42,199 --> 00:01:44,199 the space station . And then we use 39 00:01:44,199 --> 00:01:45,921 what's called differential GPS 40 00:01:45,921 --> 00:01:47,810 processing to get a more accurate 41 00:01:47,810 --> 00:01:49,643 position solution for the test . 42 00:01:53,279 --> 00:01:56,900 It's another band of frequency . So GPS 43 00:01:56,910 --> 00:01:59,132 has L one and L two which are different 44 00:01:59,132 --> 00:02:01,466 frequency bands , L five is a different , 45 00:02:01,466 --> 00:02:03,577 is a different frequency band . So it 46 00:02:03,577 --> 00:02:05,521 gives it more flexibility and more 47 00:02:05,521 --> 00:02:07,743 accuracy as well . The more frequencies 48 00:02:07,743 --> 00:02:07,089 you have , you can correct for the 49 00:02:07,099 --> 00:02:10,619 atmospheric errors . It also gives you 50 00:02:10,690 --> 00:02:13,330 more redundancy in the electromagnetic 51 00:02:13,339 --> 00:02:15,228 spectrum just having more ways of 52 00:02:15,228 --> 00:02:17,172 getting the information to be true 53 00:02:17,172 --> 00:02:19,509 source for the test community . And 54 00:02:19,520 --> 00:02:21,742 then also potentially a better position 55 00:02:21,742 --> 00:02:23,909 solution for airplanes in the future . 56 00:02:23,910 --> 00:02:26,132 If they go with this sort of hardware L 57 00:02:26,132 --> 00:02:28,354 five U five A implementation , so if we 58 00:02:28,354 --> 00:02:30,577 don't do this test , then we don't have 59 00:02:30,577 --> 00:02:32,688 the answers of if this implementation 60 00:02:32,688 --> 00:02:35,369 is realistic and don't have this asset 61 00:02:35,380 --> 00:02:37,436 available to the community , I think 62 00:02:37,436 --> 00:02:40,779 it's really cool to fly and get data . 63 00:02:40,789 --> 00:02:43,229 And in this case , see what happens 64 00:02:43,240 --> 00:02:45,462 like we have some predictions , we have 65 00:02:45,462 --> 00:02:47,684 some general things , but we'll have to 66 00:02:47,684 --> 00:02:49,851 see what , what data we get in the air 67 00:02:49,851 --> 00:02:51,962 and I've worked with GPS before and I 68 00:02:51,962 --> 00:02:54,073 really , so it's kind of cool to be a 69 00:02:54,073 --> 00:02:54,779 test of GPS in this case .
