An experimental GPS receiver, built by Surrey Satellite Technology Limited (SSTL), has successfully achieved a GPS position fix at a 23,300-kilometer altitude — the first position fix above the GPS constellation on a civilian satellite, according to the company.
SSTL’s SGR-GEO receiver is collecting data that could help the company to develop a receiver to navigate spacecraft in geostationary Earth orbit (GEO) or even in deep space.
