SSTL deliver on-board GPS receiver to SpaceDev

Surrey Satellite Technology Limited (SSTL), Guildford, UK, has delivered the first of four flight SGR-10 GPS receivers to SpaceDev, Poway, CA.

Surrey's Space GPS Receiver (SGR) is a 24-channel C/A code multi-antenna receiver designed for positioning, timing and orbit determination of low Earth orbiting spacecraft. The SGR is able to initialise itself in orbit within four minutes from a cold start, and determines position to a typical accuracy of 10 metres. The SGR has been used on a number of satellites, including OSC/NASA's DART Rendezvous mission, ESA's PROBA mission, the Disaster Monitoring Constellation (DMC) satellites, and will be used for the RapidEye constellation.
