MLS测量误差与地面台站坐标误差间的关系

摘要

Ground equipment is composed of range finders, azimuth and elevation. The coordinates of Plane at the airport over the landing is the three intersection of quadratic surface which include the hemispherical surface provided by the range finder, the taper surfaces with y axis and z axis as the radial provided by the azimuth. Through analysis of the relationship between the ground station coordinates error and its import systematic errors, calculation and simulation are given.%MLS地面设备由测距仪、方位台和仰角台组成。飞机飞抵机场上空距其着陆点的坐标(XYZ)就是测距仪提供的上半球面与方位台提供的以Y轴为径向的圆锥面和仰角台提供的以Z轴为径向的圆锥面三个二次曲面的交点。本文通过分析得出地面台站坐标误差与其引入的系统误差间的关系，并给出了仿真计算。
