几种典型航天测控系统的最优布站

UPTIMAL STATION ARRUNGOMENT OF TYPICAL TTC SYSTEMS

在测轨道某点风险函数最小准则下，研究了几种典型测控系统的最优布站和特性。这些系统是：测角（α、γ）体制的光学经纬仪；测距测角（Ｒ、Ｅ、Ａ）体制的脉冲雷达；测距离（Ｒ）［或测速（Ｒ）］体制的多Ｒ［或多（Ｒ）］系统。导出的结果公式计算十分简单，能估算测控系统定轨的精度极限。对试验场的设备布局、安置勘点、总体设计、精度估算与控制等。

Optimal station arrangement and properties of some typical TTC systems are studied under the condition of minimizing the risk function of a given trafectory point. The systems include optical theodolites of angle acquisition(a,)system,pulse radars of ranging and angle acquisition (R,E,A) system,and multi_R (or multi_R) instruments of ranging (R) or ranging rata (R) system. As the result,the deduced formula are very simple and easy to calculate, and are able to estimate the limit of accuracy of trajectory determined by the TTC systems. It is valuable for reference to the instrument arranging, station position selecting, TTC system planning, accuracy estimating and accuracy controlling, etc., of space test site.
