      There are satellites that support APRS with data rates less than 100 bps, 
but a satellite with a PacSat BBS is probably the most useful to you as 
files can be stored on the satellite and then retreived. The 1200 bps 
satellites were designed to be accessed with an omidirectional antenna, but 
only AO-16 is left and it is semi-operational. There are a some 9600 bps 
PacSats, but they require a directional antenna with 12 dBic or more gain. 
The uplink could use an omidirectional antenna if you have power to spare, 
but a directional antenna would require much less RF power.

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.
Thanks Brian

If you could expand on your request to "control a robot from a satellite"
with more specifics then you are likely to get better ideas and 
suggestions.
Some additional details like... Where would the command station and robot 
be
located? How much time would you need to command the robot each day? What
mode would the commands be sent in (digital, audio, FM, SSB...).
Hope your project goes well.

My goal is to be able to control a robot from a satellite, I'm with a 
group
that is trying to compete in the lunar X prize, here's a video of our
earthbound test rover. Also what would be the best transmitter & receiver 
to
buy for this goal?

Yes.  You need to have a amateur radio license for the bands you wish to
work, specifically the "uplinks".  For example if you wanted to work some 
of
the LEO satellites like AO-51, SO-50, etc. you need at least a 
"technician"
class license.  Take a look at ARRL's information as to what bands you can
operate with which license (see:
http://www.arrl.org/FandES/field/regulations/bands.html).
Information about the amateur satellites in operation can be found at
www.amsat.org.
Next question?  :-)

Hi,
This will be the first of probably 1000 questions. Do I need licenses to
work with amsat satellites?
Thanks, Brian
