The spaceborne GPS receiver for Tsinghua nanosatellite

This work presents the latest research & development achievement of spaceborne GPS receiver at Tsinghua Space Center (TSC). Based on the commercial-off-the-shelf components released by Zarlink Semiconductor, TSC has completed the development of spaceborne GPS receiver for the nanosatellite project. The GPS receiver features high dynamics at low power, mass and cost, which makes it suitable to provide positioning, velocity and time for micro/nanosatellites especially. A series of recent tests have validated its capability. Some new improvements have been made to fulfill the requirement of the coming space mission.
