As the measuring equipment of the navigation receivers, high precision pseudorange signal is generated by navigation signal simulator. Pseudorange error is mainly from modeling error in high dynamic scenarios, but it is mainly from phase quantization error of digital implementation process in high precision scenarios of evaluating receiver’s pseudorange accuracy. Is this paper, according to the implementation principle of carrier and code DDS, the causes of the phase quantization error is analyzed and the pseudorange error formula is derived and the simulation results are given. Analysis and simulation results show that phase critter originated by carry phase truncation effects measurement result of zero value and cannot be ignored. The conclusion can guide the design of navigation signal simulator.

The article presents the calibration problem of a navigation signals simulator while ensuring the measurements uniformity of coordinate and time measuring instruments. The method of determining the carrier frequency cycle fractional part in the simulator RF circuit output and standart deviation estimate of the pseudorange generation error by the simulator on the carrier phase with using of an oscilloscope is presented. The method essence is to determine the phase difference between two signals: the simulator absolute calibration with a single RF output – the phase difference between the navigation signal generated by the simulator and the reference harmonic signal; the simulator relative calibration with two or more RF outputs – the phase difference between the navigation signals generated by the simulator from different RF outputs. The applying of the simulator absolute calibration by the carrier frequency phase to solve the receiver calibration problem by the carrier frequency phase is shown, which will significantly simplify the implementation of the promising Integer-PPP technology. Presented the use of the simulator relative calibration to determine the accuracy characteristics of angular receiver in its development and testing.
