中文摘要：

利用在模拟卫星电视信号中插入的时间信息可实现时间传递，但由于它常采用固定的卫星位置，限制了时间传递精度。为此，研究了基于轨道改正的卫星电视时间传递方法，并给出了在轨道改正的基础上实现单向和共视时间传递的计算公式。将该方法应用于我国的模拟卫星电视时间传递中，计算了从中央电视台到国家授时中心的单向时间传递结果。

英文摘要：

Time transfer can be achieved by using the time signal inserted in satellite analog ＇IV, in which the precision of time transfer is often limited by adopting a fixed GEO satellite position. A satellite-TV time transfer technique based on improved orbit is presented and the formulae for one-way and common-view time transfer are given. This technique has been applied to the satellite analog TV time transfer in China, and the results on one way time transfer from CCTV-1 to NTSC via APSTAR 6 satellite has been calculated with improved orbit.
