Satellites not allowed to intentionally "drift" out of their assigned orbital slot. When the fuel gets down to a critical level, *sometimes* they'll allow them to drift North-South in an inclined orbit to get some extra operating time out of them, but they're carefully controlled as to East-West movement. When the fuel gets _really_ low, they use the remainder to boost them up higher into a graveyard orbit. Unless something catastrophic happens, the ground controllers NEVER allow a commercial satellite to run out of fuel just sitting in it's assigned slot. Hughes Space and Communications doesn't exist anymore. They were bought by Boeing in 2000, and are now the Boeing Satellite Development Center.

Example, a marginally functional satellite was assigned free telephone status for the remote island Pitcairn.
so it may be possible to find some other satellites that still have working transponders which are not good enough for profit but could still be used by hams. Example, if the sat was designed as a Geo sat and it's Fuel runs out, it will drift out of its parking space. The transponders still work but it can not be used since its Moving and its not in its assigned parking space. we should not only check out the Geo Sats, but also Tumbling Iridium sats too.
Any one have contacts are Huges or one of the other satellite companies?

BB
before. It did generate some creative thinking.
Given all
the satellites up there and all the varied uses of
them,
eventually some of them get compromised for whatever
reason.
Is there any way any of these old relics can be reprogramed, used or otherwise "adjusted" to
suit
us? We don't need a real good S/N ratio to make
us
happy, and we are pretty good at cobbling together
whatever
we want. We have some very informed and smart people
on
this BB who know. 73 Bob W7LRD Seattle _______________________________________________ Sent via AMSAT-BB@amsat.org. Opinions expressed are
