Research on Estimation of Time Tag for GPS/INS Data Synchronization
摘要
Abstract
A real time GPS latency determination algorithm is introduce based on yaw rate matching method by incorporating GPS and inertial sensors, to solve information synchronization of GPS and INS in data fusion procedure. The result can be used for matching the time label of GPS data and inertial sensor data to improve the accuracy of the integrated navigation and vehicle states estimation. The method is self-contained in the integrated system and it could be utilized in external device. Experiment result proves that GPS latency keeps stable in short period and the modification can be quite favorable.关键词
