Autonomous tracking system for carrier rocket orbital stage motion: structure and algorithms
The autonomous tracking system (ATS) for launcher orbital stage motion, intended for determination of characteristics its motion (spatial orientation angles, motion parameters) and a current condition of the upper atmosphere density (ballistic coefficient) for increase of motion forecasting accuracy and for specification of the atmospheric entry moment is offered. For transmission maintenance of the high information transfer efficiency to the Earth and depreciation of flight tracking it is offered to use a low-altitude satellite communication system (LSCS) Globalstar and the Internet. The fixed-frequency two-system navigational receiver, the magnetometer, the satellite modem is included in ATS structure. The complex of the algorithms using the picked structure of measuring devices is described. Results of flight experiment with ATS prototype, implemented on space vehicle "Foton-M2" are described.
