概述以DME为基础的DAS方位系统是一个高精度极座标导航系统,根据地面站建造的情况,可以达到方位测量误差<0.05°,测距误差<20m。DAS是由以ICAO标准为基
Overview The DEM bearing system based on DME is a high-precision polar coordinate navigation system. According to the construction of the ground station, the azimuth measurement error <0.05 ° and the ranging error <20m can be achieved. DAS is based on the ICAO standard
