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.

Abstract Based on the traditional BOC modulation system, a new navigation signal system based on FH-BOC is proposed in this paper. The simulation and verification of FH-BOC signal are carried out, and the modulation characteristics, code tracking performance and anti-interference performance of FH-BOC signal are analyzed, and the advantages and disadvantages of the modified system are verified. The results show that FH-BOC signal has good ranging and anti-interference ability, which is suitable for navigation system and can reduce the ambiguity of BOC signal’s secondary peak to a certain extent. At the same time, the T has important scientific significance and application value to improve the countermeasure capability of other satellite navigation systems.
