Brian...
To transmit a picture which has any resolution would require a large file and a lot of clear, interference free reception...perhaps you might take a look at APRS which can use GPS to define location. Trying to send pictures will use up many interference free passes on a satellite which leaves no time for other users.
Turning on, turning off, movement code is much simpler. Google: Packet Radio control, AX.25, APRS. If you use existing code, forego the pictures for a change in location on a displayed map, and use the current crop of Packet radio Satellites, with an Amateur Radio license of course, your communications project is very doable and might give you 9 to 12 passes per day to conduct your experiments.

Hi,
In a perfect world here is what I would like to happen, satellite fly's by, rover sends a packet (or email) of info containing a photo of its current location and some sensor info. The next time the sat comes the
rover
receives its instructions (move 5 feet forward, power down & then power up and take photo and be ready to send info to sat when it comes by). There
is
several reasons for doing it this way .We need the practice powering up
and
down, we also need to see that the rover has a good plan if it misses instructions for one reason or another.
