To get good coverage you need as many LEO satellites as possible so they should each be as small as possible. Intersatellite linking could be done via automated ground stations. This eliminates the need for high-power transmtters and/or high-gain antennas on the satellites for interlinkng. It's better to put that gain and power consumption on earth. Eveything on the satellite costs more than its weight in gold as launch costs are $700 per ounce.

    It seems more reasonable to focus on projects that we can pay to launch or

  Wacky idea No 357

  Perhaps a longer term piece of AMSAT research could be to develop a subsystem for LEO satellites that detects and then connects users between passing LEOs. This would allow short term intersatellite communication.  Very tricky, but a nice project where boards are made available to anyone who would like to add this facility to their LEO Sat.
