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.

P3E is a HEO with the same engine as P3D and no benefactor funding a

It seems more reasonable to focus on projects that we can pay to launch or
where someone has already donated the launch.

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.
Thanks
