本文叙述了1974年11月3日所进行的一次跟踪试验,在这次试验中,地面站通过中继卫星对空间飞行器成功地进行了24小时的跟踪和测轨。在试验中,使用了一种新的方法准确地计算了应用技术卫星(ATS—6)的轨道数据。通常卫星跟踪包括一个由很多地面站组成的跟踪网和数据收集设备。然而这种新方法是用一个地面跟踪站通过轨道已经确定的同步卫星同时与几个安装在不同地点的地面应答机协同工作。ATS—6跟踪测量数据的随机误差在整个24小时之内,测速为0.3mm/秒,测距为1.5米。分别使用两组数据,通过对卫星轨道的重复计算,可以使ATS—6的速度误差最小达到0.2cm/秒,距离误差最小可达30米。在同样时间之内,最大的距离误差约为250米,速度误差为2cm/秒。利用两颗卫星ATS—6和ATS—3同时跟踪哥达德飞行中心地面站来确定地面站的位置也是可行的。在跟踪的前10小时之内,站址精度可以校正到大约100米的数量级之内。 This article describes a follow-up test conducted on November 3, 1974, in which ground stations successfully conducted 24-hour tracking and orbiting of spacecraft via relay satellites. In the experiment, a new method was used to accurately calculate orbit data of Applied Technology Satellite (ATS-6). Satellite tracking usually includes a tracking network consisting of many ground stations and data collection equipment. However, this new method uses a geostationary tracking satellite that has been identified by the orbit to simultaneously work with several surface transponders installed at different locations. ATS-6 tracking measurement data random error in the entire 24 hours, the speed of 0.3mm / s, ranging from 1.5 meters. Using two sets of data respectively, the ATS-6 can achieve a minimum speed error of 0.2 cm / second and a minimum distance error of up to 30 meters by repeating calculations of satellite orbits. In the same time, the maximum distance error is about 250 meters, the speed error is 2cm / sec. It is also feasible to use the two satellites ATS-6 and ATS-3 for simultaneous tracking of the Godaddy Flight Center ground station to determine the position of the ground station. Within the first 10 hours of tracking, site accuracy can be corrected to within about 100 meters.
