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.
