在卫星电视授时系统方案中，为确定标准秒信号从发射站经卫星到用户接收站的传播时延值，需要知道收、发地面站及卫星的坐标，所以，在高精度的卫星电视授时系统中，需要建立高精度的同步卫星定位同。本文提出在没有卫星定位同的条件下，用非坐标方法来确定卫星时间信号到用户的传递时延，其授时精度为几μｓ。 In the satellite television timing system scheme, in order to determine the propagation delay of the standard second signal from the transmitting station via satellite to the user receiving station, it is necessary to know the coordinates of the receiving and transmitting earth stations and satellites. Therefore, in the high-precision satellite television timekeeping system In the need to establish high-precision synchronous satellite positioning with. This paper proposes to use the non-coordinate method to determine the transmission delay of the satellite time signal to the user in the absence of the same satellite positioning, the timing accuracy of which is several μs.
