GPS signal fast acquisition method aided by inertial information

  • The signal acquisition time affects the performance of global positioning system (GPS) receiver directly under high dynamic conditions. Based on the analysis of traditional acquisition method aided by external information, an improved fast acquisition method was proposed which was aided by inertial information and ephemeris supplied by GPS/inertial navigation system (INS) integrated navigation system. This new method was composed of coarse acquisition and fine acquisition,of which the implementation method and acquisition performance were analyzed. The acquisition algorithm was validated in efficiency by MATLAB/Simulink system-level simulation and Monte Carlo test. The simulation results show that when C/A code resolution is ensured and high carrier frequency resolution is obtained using this new method, the acquisition time can be reduced obviously so that the acquisition performance of high dynamic GPS receiver can be improved. Compared with the conventional GPS signal acquisition method, the total acquisition time can be reduced to 2%~3%.
