The invention relates to the field of the design of satellite navigation receivers, and specifically discloses an inertial information auxiliary satellite deep combined loop. The inertial informationauxiliary satellite deep combined loop comprises an inertial information auxiliary tracking loop and an inertial information discriminant tracking loop. The inertial information auxiliary tracking loop comprises an auxiliary information anomaly discrimination module, an inertial acceleration auxiliary module, a loop optimal bandwidth calculation module, an equivalent carrier-to-noise ratio calculation module, an interference-to-signal ratio estimation module and a loop PIT adjustment module, which are connected with the output end of the inertial information discriminant tracking loop. The inertial information auxiliary satellite deep combined loop further comprises a correlator and a three-path loop connected with the output end of the correlator. Through full fusion of inertial information and satellite navigation information, reliable design of a satellite receiver and optimal design of the parameters are realized. The algorithm is simple to apply. There is no complex equation or equation needing heavy computation. Algorithm programming on a DSP or FPGA hardware platform can be guaranteed in the aspects of both real-time performance and amount of computation, namely, engineeringimplementation is easy.
