A new Dead Reckoning (DR) navigation algorithm based on speed pulse for land vehicles provides real-time latitude and longitude calculations, while a robust GPS/DR integrated navigation data fusion method improves precision and works effectively even in GPS signal-interfered environments.

This work presents a method to mitigate stochastic errors in low-cost MEMS gyroscopes using Allan variance analysis, real-time averaging, least square extrapolation, and a Kalman filter. The method effectively reduces errors, compensates for constant drift, and minimizes measurement variance, making it suitable for various MEMS gyroscopes in static and dynamic scenarios.

This research introduces a fourth-order Runge-Kutta algorithm to enhance the accuracy and performance of Strapdown Inertial Navigation System (SINS) calculations compared to traditional high-accuracy digital integration methods.
