Abstract

A simple and small K-band (30/20GHz) mobile earth station for domestic satellite communication was developed. This mobile earth station ( MES ), with 2.7mϕ non-divided Cassegrain antenna, has 132CH telephone transmission capacity and can be transported to any desired location by a truck or helicopter, if necessary. A satellite communication system using MES( mobile earth station ) intended for emergency relief or temporary communication purpose in domestic communication, will be a future effective system for either domestic, regional or international use. This paper describes (1) system outline, (2) K-band satellite link design philosophy, (3) equipment outline and (4) total system experimental results using Japanese Communications Satellite[l]. Results ably illustrate its system effectiveness.
