Abstract:Based on the test requirement of navigation user equipment, the test technology for BD-1 receivers is discussed.A test system was designed based on a mixed-bus framework,the detail solution to some key points was suggested.DDS technique was adopted to simulate the frequency offset and time delay of the dynamic navigation signal. Rapid acquisition and high precision measurement were achieved using a parallel waiting-style digital correlator structure. Automatic test software was developed based on MVC (Model...
Keywords:test technology  simulation of dynamic navigation signal  rapid acquisition  test data processing
