[amsat-bb] I'm dreaming of a Medium Earth Orbit.......

Did anyone see the Soyuz launch from Arianespace a few days ago and think how nice it would be to have an amateur radio satellite somewhere above LEO ?

Interestingly, the launch of 3 communication satellites providing internet services to remote areas, was to an altitude around 8000km. - An unusual destination.
Apparently the 'latency' or time delay on signals from 36,000km is too high for an internet service, whereas the number of satellites needed for a constellation at LEO is too many.

The company O3B  (Other 3 Billion) decided that MEO at 8000km which is between the 2 Van Allen belts answered their needs.


For the launch, the satellites were mounted on a cylindrical  launch adaptor, (see pics in link) the inner part of which looks an ideal place for a 3U cubesat secondary payload.

Wouldn't it be nice to get something up to that altitude with Omni antennas, or a gravity gradient boom with a simple beam and about 4 Watts output !

Oh well, back to dreaming of a white Christmas
