摘要

惯性导航系统(INS)与全球定位系统(GPS)接收机的集成是近年来研究的热点。利用该集成系统,可以获得运动平台的精确姿态。本文主要讨论了GPS/INS集成的精确姿态确定问题。提出了一种基于线性两点多项式和二次五点多项式的线性凸组合的高精度姿态确定算法,用于对GPS/INS姿态数据进行滤波和预测。通过实际GPS数据与仿真INS数据的集成实验,验证了该方法的有效性。

An algorithm for integrating GPS/INS attitude determination system
The integration of inertial navigation system (INS) with Global Positioning System (GPS) receivers has been an area of intensive research in recent years. Using such an integrated system, precise attitude of moving platforms can be obtained. The discussion in this paper focuses on precise attitude determination by GPS/INS integration. A highly accurate attitude determination algorithm of a linear convex combination of a linear-two-point and a quadratic-five-point polynomial to filter and predict GPS/INS attitude data is presented in this paper. An integration experiment of real GPS data and simulated INS data shows the validity of this method.
