Summary:The testing and verification is an important means to ensure the quality of GNSS receivers, which is essential in all stages of R&D. The hardware design and algorithm of high precision GNSS RF record & playback system are introduced in this paper. This system had been applied to acceptance test of Beidou2 high precision receivers and the chips in 2015. The system achieved 16bits(I&Q) bit depths and 50MHz bandwidth which provides a high fidelity GNSS signals with complex RF signal environments and interference to DUT.
