Abstract

Satellites have been continuously evolved from the primitive form of space repeater to the core element of data processing and distribution hub in modern communication network. This changes inevitably induce great impact on the structure and role of satellite in all applications using satellite, both for the civilian and military sectors.

In this talk, aspects of the required functional blocks of the modern satellite is initially discussed followed by the discussions on the recent technical development in commercial, experimental, and military satellites. Then the additional aspect of technical advances and trend to cope with the newer user demand will be briefly assessed. Finally, the outlook for the respective areas of satellite use in broadcasting, communications and tactical applications will be summarized.
