苏联除了已发射“虹”、“地平线”、“荧光屏”等三种实用型同步通信卫星之外,还计划在最近几年内发射“射线”、“波浪”、“航向”等三大系列的同步通信卫星。本文将简单地介绍这三大系列卫星的任务及其主要技术指标。“射线”卫星系列“射线”系列计划发射八颗卫星,其中射线-1、-2、-3、-4等四颗卫星用于国际通信,射线-P_1至P_4用于国内通信。这个系列的卫星能够提供电话、电报、传真以及电视和无线电广播等不同的业务。
In addition to launching three practical synchronous communications satellites such as Rainbow, Horizon and Fluorescent Screen, the Soviet Union plans to launch three major series of synchronization such as “ray”, “wave” and “heading” in recent years Communications satellite. This article will briefly introduce the tasks of these three series of satellites and their main technical indicators. The “X-ray” satellite series “X-ray” series plans to launch eight satellites, of which four satellites such as rays -1, -2, -3 and -4 are used for international communications and the rays -P_1 to P_4 are used for domestic communications. This series of satellites can provide different services such as telephone, telegraph, fax and television and radio broadcasting.
