三点测距副站技术

设计和研制的两个副站（乌鲁木齐站和广州站）和北京的主站相互配合形成三点测距系统，可以完成对风云二号卫星的测距定轨任务。文章着重介绍了副站的组成、作用和功能技术指标等。它的设计方法与国外同类技术相比颇具特色。经过对日本气象卫星进行的几年跟踪测试，及最后通过对风云二号卫星执行任务的验证，确认了副站方案的可行性，设计的合理性。

A TURN AROUND STATION IN TRILATERATION RANGING SYSTEM

The Ulumqi and Guangzhou turn around ranging stations developed by the company of the author and the Beijing master station compose a three point ranging system.This system can perform the function of the ranging and orbit determination of FY 2 satellite.This article mainly introduces the configuration,function and technical specification of the turn around ranging stations.Compared to the same type of the products abroad,this type of station has some distinguished features and has passed the design review of all levels. The stations were used in the tracking of the Japanese Meteorological satellite.The design of the turn around ranging station has been proved to be feasible and reasonable by the successful ranging and orbit determination of the FY 2 satellite.
