In Orbit Antenna Pattern Tests and Service Coverage Measurements of COMS

摘要

Communication, Ocean and Meteorological Satellite (COMS) is the multi-purposed Korean geostationary satellite funded by Korean government ministry, and is to supply communication services, ocean and weather observation for 7 years. COMS was launched by Ariane-5 on 26th June 2010 and arrived successfully to operational geo-stationary orbit 128.2E. It features a multi-beam Ka-band Communications package, a set of equipments to study Ocean Ecosystem to aid the fishing industry and a Metrological weather observation system. The multi beam Ka-band antenna in orbit test campaign was conducted by Electronics and Telecommunications Research Institute team. A brief outline on functional and operational capability including software and hardware used for in orbit test validation of Ka-Band antenna system is addressed. After successful in orbit test, service coverage measurement for COMS Ka-band antenna was performed. Methodology and results for service coverage measurement are addressed also. The antenna in orbit test results show COMS Ka-band antennas performance was not degraded by satellite launch and service coverage are formed as we designed over the south Korea peninsula.
