AbstractBy joint effort of the US and West Germany a Sunprobe will be launched by 1974 named HELIOS. In the Telecommunications Subsystem the Telecommand Receiver has a keyrole as Experiments have to be switched up to 2 AU distance from earth. The input power at the Receiver Equipment input terminal is -147 dbm with SNR of 6 db in 2 BL(o) = 32,5 Hz Loop Bandwidth. To achieve this sensitivity a Receiver in Phaselocked loop techniques with a low noise Preamplifier had to be developed. In cooperation and with consultance of well known US-Scientists it was possible to design and develope the S-Band Receiver up to the Qualifikation Model in less than two years. This report shall give a survey over concept and design of the receiver and some special experiences during development and integration tests.
