How can you stay within a 802.11 IEEE Standard and have the range to talk to something in low earth orbit? Is this system going to be just for receiving data from these satellites?

just for receiving data from the satellites.

What frequency will the satellites be using for transmit?

There are tests due from the Internation Space Station for ‘HAM Video’ that will be using 2.4Ghz - transmitting around 10w EIRP - to pick this up from the ground, you will need pretty much at least a 1.2m dish - capable of being pointed accurately at the space station as it passes - this will deliver 720x480, or 352x240 resolution video at upto 2.0Ms/s.

Satellites in a 600mile orbit will probably require a slightly better gound station due to free space losses - but at least doppler shift should be less of an issue.

Will you be loking at VHF / UHF for the downlink from these satellites to make it more accessible??
