Abstract： High performance navigation test signal simulator reflects the construction and application of satellite navigation system technology in national. The project involved high precision of navigation satellite orbit simulation， precision navigation signal generation， carrier phase precision control and transmission error of many advanced technologies such as simulation， is one of the strategic high ground for international satellite navigation field. Its performance level will directly affect our competition ability of satellite navigation terminal products in the international market. With the advancement of construction and application of Beidou-II satellite navigation system， measurement， high dynamic state， anti-jamming and etc. user terminal detections have become the GNSS high-end bottleneck of the development and application on the user terminal. Foreign countries use their high-end high-performance navigation test signal equipments to restrict our satellite navigation system construction and development， also the equipments are embargo to us. The research has independent intellectual property rights of high performance navigation signal simulator test and calibration technology is helpful to improve China's satellite navigation system of the international competition ability， promote the satellite navigation terminal product development level in our country， accelerate the development of navigation equipment demonstration application industrialization has extremely important significance. Topics from the point of research approaches can be divided for system and high-performance two key points， in which "multi-system" is to achieve more sign system and the ground navigation satellite navigation signal enhancement signal simulation； "High performance" is to further breakthrough in both the signal simulation technology based on high precision simulation performance bottlenecks. Finally， in order to give full play to the testing system of testing effect， improve the system availability， we need to study related testing theory and implementation technology. Research involved more than algorithm model and the techniques include high-performance GNSS system simulator mathematical simulation technology， precision signal time delay control and high quality signal generation technique， high precision， high dynamic GNSS radio frequency signal simulation， simulation of GNSS signal high accuracy checking and credibility evaluation technique， etc.

Key Words： The multi-system navigation simulation signal source； The test signal enhanced simulator； Simulation and test of enhancing signal
