Ground Stations
The first ground station of the Institute of Astronautics (IA) (S-band) and the Mission Control Center got operational in August 2006. This S-band antenna is constructed for the transmit and receive of satellite data from LEO and GEO, and thus encompasses the entire S-band frequency range (2.0 to 2.3 GHz).
The further and intensive research activities in the field "telepresence in space", especially through the project "LISA-MS" required the investment of an additional high-performance Ka-band antenna (20/30 GHz). These future orientated high-performance frequency band allows for high-data transfer, for example, image data in high definition quality. Especially for Earth controlled robotic missions a secure real-time transmission is important. The link configuration for such robotic missions are using a geostationary relay-satellite, to allow a longer contact time.
In the commercial area also draws from increased use of Ka-band technology to meet the demand of television broadcasts in HD quality.
Furthermore, this antenna is equipped with special measurement equipment to perform high-precision in-orbit measurements of communication satellites or acceptance tests from others ground stations. Because of these special measuring equipment of the IA Ka-band ground station, a research and development cooperation with the French satellite operator Eutelsat was created. After intensive series of tests the system was certified as a reference station for ESVA ( Earth Station Verification Acceptance ) - tests.
The UHF / VHF antenna was mainly realized for the TM/TC (Telemetry TeleCommand) operations of LEO satellites. In the past, the station was used for video downloads of the LAPAN TUBSAT mission. Since 2013, this antenna is used for the in-house CubeSat missions First-MOVE and MOVE-IIa/b.
