多站混合定位系统的平面误差分析

基于应答方式的多站机场航管定位系统可同时采用时差和距离测量技术,应用最小二乘法和误差估计理论,对按圆周均等布站的四站、五站和六站定位系统所做的相对测量误差分析表明,利用二次监视雷达所给出的测距信息,并通过有限增加冗余测站,将能有效的提高多站定位系统的平面定位精度。

Plane Error Analysis of Combined Positioning System for Multi-Station

The technology of the time difference and range measurement can be simultaneously adopted for multi-station positioning system for air traffic control based on radio transponder.By least square method and error estimation theory,the error analysis on relative measurement on the basis of the station arrangement of equal distributions in circumference for 4-station,5-station and 6-station proves that the positioning accuracy in plane of multi-station positioning system can be enhanced by making use of the ran...
