Beidou RDSS inbound receiver calibration system and method

The invention provides a Beidou RDSS inbound receiver calibration system and method, and relates to the technical field of measurement and calibration of special test equipment for satellite navigation. The method comprises the following steps: acquiring Beidou short message user machine inbound data by using a vector signal analyzer to obtain an ideal Beidou RDSS inbound signal chip; generating baseband data of an inbound signal by quantitatively adding a phase modulation error, a direct current offset and an inbound time delay; a digital baseband is modulated to radio frequency through the vector signal generator, so that the vector signal generator has the function of a special inbound signal simulator, and the Beidou RDSS inbound receiver is directly measured. The vector signal generator used in the invention is a general instrument and has a perfect magnitude traceability system, so that the calibration device provided by the invention can effectively solve the problem of magnitude traceability of the Be
