We track how the Earth, how the satellite is 6 00:00:20,090 --> 00:00:24,090 moving around the Earth, and how the Earth is moving around the Sun. We have 7 00:00:24,110 --> 00:00:28,120 algorithms on-board that allow us to turn the spacecraft one direction 8 00:00:28,140 --> 00:00:32,130 or another to make sure that we keep it thermally safe and power positive. 9 00:00:32,150 --> 00:00:36,150 We have other algorithms that keep our orbit, because the orbit degrades over time 10 00:00:36,170 --> 00:00:40,200 so we have what we call thruster maneuvers and delta-v maneuvers which allow us 11 00:00:40,220 --> 00:00:44,210 to raise or lower the orbit. We have a very large spinning instrument 12 00:00:44,230 --> 00:00:48,240 on the GPM called the GPM Microwave Imager, 13 00:00:48,260 --> 00:00:52,270 GMI. Because it's a spinning object, it introduces jitter to the whole 14 00:00:52,290 --> 00:00:56,320 spacecraft, so the whole spacecraft kinda shakes with it. We can't test that on the ground, 15 00:00:56,340 --> 00:01:00,330 so it'll be a nice culmination to the seven years of work that I've spent on GPM. 16 00:01:00,350 --> 00:01:04,390 [ raindrops ] 17 00:01:04,410 --> 00:01:08,430 18 00:01:08,450 --> 00:01:12,440 19 00:01:12,460 --> 00:01:16,470 [ beep beep... beep beep... ] 20 00:01:16,490 --> 00:01:20,530 21 00:01:20,550 --> 00:01:24,530 22 00:01:24,550 --> 00:01:25,799
