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.

We cover launches, missions, satellites, defense, and the technology of getting humans to space, alongside the psychology of ambition, isolation, and meaning under extremes. Articles reflect our team's collective editorial process, source verification, drafting, technical review, and editing, rather than a single writer's work.
