Trends in the control and monitoring of future European satellites
Abstract
The selection of telecommand and telemetry systems of satellites launched by the European Space Agency is discussed. Subjects reviewed include multiplexing mission support data and payload data of scientific satellites, ground station requirements for satellites in geostationary orbit, telemetry bit rates for various types of missions, the use of on-board data processing, separation of support communications and payload hardware in spacecraft and standardization of transponders. It is proposed that S-band frequency transmission, capable of accommodating up to 300 missions sharing a bandwidth of 10 MHz, be used in the control and monitoring of future ESA spacecraft; however, existing VHF facilities should be kept in operation for several years to support current programs of geostationary orbit injection. The use of L-band transmission to solve frequency regulation problems is also considered.
