Аннотация:At present, there is a need for vehicle–board antenna system of COSPAR–SARSAT. The antenna system consists of a transmitting antenna and a receiving antenna. In this paper the antenna system of COSPAR–SARSAT for series spacecraft “Meteor–M” is designed and presented. In addition to receiving and transmitting antennas, testing complex for full-scale test has been developed. In this paper the results of measurement of voltage standingwave ratio, radiation pattern, gain of vehicle–board antennas are presented. The obtained results satisfy the technical task for the antenna system for vehicle–board equipment COSPAR–SARSAT.
