摘　　要：介绍几种常用外部信息辅助惯导的组合导航方式。结合陆基无线电导航的特点,提出了利用无线电精确测距信息对一定区域内的飞行目标进行惯导误差修正的方案。推导出单站测距误差方程,并用最小二乘法解算出惯导修正参数。整个系统组成简单,易于实现。This paper introduces several methods in the aided Inertial Navigation System（INS） with the assistance of information outside. According to the characteristics of the terrestrial radio navigation technique,a scheme of aircraft inertial navigation error correction in a given range with the＇aid of precise radio distance measurement is proposed. The single station error equation is deduced. And the INS error correction coefficient is calculated with the least squares method. The entire system is compact and easy to implement.
