Small spacecraft for experimental studies of the conditions of space radiocommunication KVAZIGLOBALNYH SATELLITE COMMUNICATION SYSTEMS

摘要

The claimed utility model relates to communication systems using kvaziglobalnyh satellite communications systems (CAS) and can be used to improve the reliability of the communication channel small-sized spacecraft (ICA) with a mission control center (MCC). The technical result of the claimed invention is considerable reduction in the number of unsuccessful communication sessions ICA with PCO. This is achieved by introducing additional onboard ICA satellite antenna with an antenna-feeder device and a backup communication channel through VHF modem. Significantly improves the accuracy of the experimental data obtained at the expense of their "anchor" to the current satellite and its position in orbit. Coordinates and the position in the orbit determined by means of additional equipment installed on board - satellite navigation equipment GLONASS / GPS and digital triaxial magnetometer. Existing sensors Sun and the horizon established in the analogue does not provide the necessary accuracy in determining the position of the satellite in orbit. 5 yl.
