[time-nuts] OT: Far-out space navigation from sideways satnav signals

[David J Taylor]

An interesting novel use of GPS "stray" signals....

"ESA’s retired GIOVE-A navigation mission has become the first civilian 
satellite to perform GPS position fixes from high orbit.  Its results 
demonstrate that current satnav signals could guide missions much further 
away in space, up to geostationary orbit or even as far as the Moon. "  See:
