00:00:08,050 --> 00:00:12,050
The Guidance, Navigation, and Control Lead basically is in charge of

4
00:00:12,070 --> 00:00:16,060
all of the components to make sure the spacecraft is pointed where the scientists

5
00:00:16,080 --> 00:00:20,070
want it to be pointed. 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.
