Bruce,

Yes, some do, although not FO29.

I'm pretty sure NASA sponsored a GPS system experiment on AO40 and that 
this was the first GPS system to fly *outside* the ring of GPS 
satellites. I *think*  I can remember an AMSAT bulletin reporting the 
success of the experiment.

Space Today list three amateur satellites as carrying GPS but don't 
include AO40. Space today lists: PoSAT-OSCAR 28, Thai-Microsat-OSCAR 31, 
CanX1
