Will this recent talk of GEO sats leave the southern hemisphere out fo the picture ?

Don't worry about the Southern Hemisphere, geostationary satellites sit over the equator, by definition. However, of more concern is coverage of the _Eastern_ Hemisphere... However, if the Intelsat deal goes ahead, then it's quite possible we'll have multiple birds to enable near global coverage, from what I've read here....

I really don't see much of a technical challenge with a geo, but if that is the lie of the lie, so be it.
A cell phone has about the same degree of difficulty...
And who gets the 1st third....or will all three be installed at the time??
I'd rather see one similar to AO7 or 8 with ssb/cw, and bandwidth to enable many users, rather than the dumb FM voice (2 user) bird AMSAT-NA spent all that money on...

Disagree: I learn....
Pulling for P3E...

My oh my... I enjoy technical challenges out of just about every opportunity. Setting up a GEO dish from a briefcase seemed like a challenge to me. Here was my take for AO-40, which moved so slowly I guess to Dave, it was not a techincal challenge either.

On a related issue I was wondering what will happen after the satellite runs out of fuel to maintain it's position in 12+ years time.
Don't they end up in a graveyard orbit, which would give significantly different coverage ?
Will a Phase-4 AMSAT Payload still receive power from the solar panels/batteries after the primary payload has reached the end of it's useful life ?
