Abstract

This invention relates to one GPS / INS combination position guide system and its speed test correction method, wherein, the system comprises CPU unit, INS module, GPS receiver and touch screen control unit, wherein, the INS module generated speed impulse signals and movable rotation signal into GPS receiver impulse signal input end and angle signal input end; GPS receiver position guide signal output end is through latitude signals through signal speed impulse displacement value, speed impulse signal into position guide signal input end.

Description

technical field [0001] The invention relates to a GPS / INS combined positioning and navigation system and a rate detection and correction method thereof. Background technique [0002] The mainstream technology in the vehicle navigation market is GPS (Global Position System). The GPS system calculates positioning information by receiving wireless signals sent by 24 satellites distributed in the sky. It has the advantages of global, all-weather, high-precision, and real-time positioning. However, due to the straight-line propagation characteristics of wireless signals, its dynamic performance and anti-interference ability are poor. , When the GPS receiver is near a tunnel, shade or tall building, the satellite signal is blocked, affecting accurate positioning or even unable to locate. [0003] The INS (Inertial Navigation System) system has autonomous navigation capability, and can independently provide positioning and navigation information such as carrier attitude, speed and...
