这是基于美国海洋大气局的计划,预计到1983年2月所能达到的接收能力图,海洋大气局打算在印度和泰国两个站安装记录设备。图中实线表示美国接收站的覆盖范围,虚线表示国外接收站的覆盖范围。在跟踪与数据中继卫星未发射前,MSS数据的覆盖范围如图所示,而TM数据只能在美国格林贝尔站才能接收到。但在此之后,全世界(除了在印度有一小块盲区外)的MSS和TM数据都能实时中继到美国。
This is based on the plan of the United States National Oceanic and Atmospheric Administration and is expected to reach the reception capacity map as of February 1983, with the intention of installing a recording facility at two stations in India and Thailand. The solid line in the figure shows the coverage of receiving stations in the United States and the dotted line shows the coverage of foreign receiving stations. Before the tracking and data relay satellites are not transmitting, the coverage of the MSS data is as shown, and the TM data can only be received by the Green Belt station in the United States. But since then, MSS and TM data worldwide (except for a small blind spot in India) can be relayed to the United States in real time.
