由于我国试验通信卫星发射成功,引起了许多部门对卫星通信的重观,有的部门正在筹建专用卫星通信网。他们首先遇到的问题是费用问题,即建立多大规模的系统,该花多少钱。虽然我国卫星通信地球站的研制工作在1976年左右就已经取得了成果,但是真正推广应用还是近几年的事,积累的经验还不多。国外一些发达国家研究生产卫星通信地球站已经有将近20年的历史,产量也比较大,他们在费用方面的经验公试或许有更多的参考作用。现将其较典型的数据编译如后,供大家参考。 Due to the successful launching of China’s experimental communications satellite, many departments have been revisiting satellite communications. Some departments are planning to build a special satellite communications network. The first problem they encountered was the issue of cost, how much system was built and how much. Although the development of China’s satellite communications earth station has achieved results around 1976, the real promotion and application are still few things in recent years, and the accumulated experience is small. Some developed countries have studied and produced satellite earth stations for communications for nearly 20 years and have relatively large quantities of output. Their empirical experience in fees may have more reference. Now it is more typical data compiled, for your reference.
