就目前而言,许多地区广播发射台信号来源通常是从卫星接收。然而卫星接收信号容易受到天气的影响例如雨雪雷等。而且目前大部分发射台尚不具有光缆、卫星以及微波等多路备份的条件,通常卫星接收信号是其唯一的信号源。所以,在现有条件基础上,需要采取有关措施对广播发射台信号源进行安全保障,使广播信号得以安全优质的传输。本文对同步卫星、同步轨道进行了说明,并提出了几条保障广播发射台信号源安全的有关措施。 For the time being, the source of signal for broadcast transmitters in many regions is usually received from satellites. However, satellite reception signals are susceptible to the effects of weather such as rain, snow and lightning. At present, most transmitting stations do not yet have the conditions of multiple backup such as optical cable, satellite and microwave. Usually, satellite receiving signals are their only signal source. Therefore, on the basis of existing conditions, relevant measures need to be taken to ensure the safety of the signal source of a broadcasting transmitting station so that the broadcasting signal can be transmitted safely and in good quality. This paper describes the geostationary satellite and geosynchronous orbit, and puts forward some measures to ensure the safety of the signal source of the broadcasting station.
