Deception jamming detection method based on pure inertial velocity assistance

Abstract

The invention provides a deception jamming detection method based on pure inertial velocity assistance, which comprises the following steps of: performing Doppler consistency detection on each satellite by using inertial assistance information output by an inertial measurement device in a navigation stage, eliminating deception signals, and then performing position velocity calculation on a satellite navigation positioning device, thereby realizing deception jamming detection. Afterwards, the accuracy of the calculation result is detected, and the positioning reliability is improved. According to the method, the deception signal can be rapidly detected under the condition that deception jamming exists, a certain deception signal removing capacity exists, the algorithm application is simple, no complex equation or equation with huge operand exists, the algorithm programming implementation on a DSP or FPGA hardware platform can be ensured in the aspects of real-time performance and operand, and engineering implementation is easy.
