| Abstract: | A novel tight integrated method is advised.Performance and integrated methods of INS-aided GPS tracking loops are studied on the base of modeling the Code-Lock Loop and the Phase-Lock Loop of GPS.The advantages and disadvantages of this new integrated method are pointed out.In the last,a mathematical simulation of INS-aided the Phase-Lock Loop verifies the analytic results. |
