Satellite platforms miniaturization enables pico-satellite, nano-satellite and other micro-satellites become a hot topic. To resolve the new problems caused by miniaturization, low power and low cost in spaceborne navigation receiver on micro-satellites, hardware design of spaceborne miniature navigation receiver based on COTS and SoC is proposed. The design includes RF module, baseband processing module, clock module and power management module. Results show that: the prototype weighs about 45g; size is 100mm×60mm; power consumption is about 3W. It has the capability to process GPS L1/L2, BD2 B1/B2 signal and can be configured to dual-mode, dual-frequency, dual-mode and dual-frequency. The miniature spaceborne navigation receiver satisfies the technical demands of mirco-satellite. It can provide new methods and thoughts for mirco-satellite navigation.
