AI Technical Summary
Existing multi-source positioning fusion solutions suffer from problems such as unstable positioning results, jitter during mode switching, and navigation interruption when signals are lost during outdoor facility inspection and maintenance. In particular, they cannot provide continuous navigation guidance in complex electromagnetic environments, affecting user experience and safety.
A dynamic weighted evaluation model incorporating historical position stability parameters is introduced, a hysteresis switching mechanism is employed to smooth the switching of positioning modes, and inertial navigation data is used for predictive compensation when the signal is lost to maintain navigation continuity.
It effectively suppresses weight distortion caused by signal fluctuations, prevents frequent mode jumps, achieves navigation continuity and availability in extreme environments, and improves positioning accuracy and stability.
