Hello I and a few others "played" with this concept back in the RS etc days. I forget (senior moment) the specific satellites and frequencies involved. I was though a bit complicated. Tracking two satellites (using a Commodore 64) and figuring muliple doppler effects, due to satellite relative speeds. Anyway it was a fun endeavor. With HEO's you could cover the whole planet. 73 Bob W7LRD Seattle

If two sats like Hamsat (or Echo) were in orbit at the same time and could see each other ...

Could User#1 uplink to Sat-A and then Sat-A would link to Sat-B (probably on one of the higher microwave bands) then Sat-B would downlink to User#2 and User#2 would uplink to Sat-B and be relayed to Sat-A and down to User#1 ??

If this could be done there would be a much larger footprint and launch costs would be far less expensive, correct?
