Are the X-band data and the C-band data processed similarly?
They are processed very similarly. Of course, as I said the X-band data is going to the Germans. The C-band data is going to NIMA or the National Imagery and Mapping Agency. There’s something interesting on this flight. The two ASTRO astronomical observation flights used the Star Tracker, and SRTM utilizes it in a new way. Can you tell me about the Star Tracker and how it is that you’re using it? We use the Star Tracker to know the exact position of the outboard antenna. We also have some Global Positioning System receivers on the outboard antenna because it’s very critical to know where that position is, so when you get the return signal you know that it’s a true signal, and it’s not just the fact of the antenna bouncing up and down. This is another way the Jet Propulsion Lab shows its innovation. They have these Star Trackers that they have from previous missions. They were sitting around. They said let’s go use them. What will we learn about the Earth from the data you do acquire on
