The invention provides a system for measuring the posture of a spin satellite by using a single-antenna navigation receiver. The system comprises a navigation receiver, an antenna, the spin satellite and navigation satellites, wherein the satellite receiver is arranged inside a satellite body of the spin satellite, the antenna is arranged on the top surface of the satellite body of the spin satellite and is arranged at the side surface of a spin main shaft of the spin satellite, and the spin satellite tracks and receives signals of a plurality of navigation satellites through the navigation receiver, and the navigation receiver adopts satellite-borne navigation equipment capable of singly or integrally receiving America GPS (Global Positioning System), Russia GLONASS, European Galileo and China Beidou satellite navigation positioning system signals. The invention also provides a corresponding measuring method. The system and the method have the advantages that the single-antenna navigation receiver is used for measuring the posture of the spin satellite, the spin satellite with the near-earth orbit height being lower than 20,000km can be subjected to posture determination only through one antenna, the weight is light, the energy consumption is low, the whole circle fuzzy degree calculation is avoided, and the like.
Description
technical field [0001] The invention relates to the aerospace field, in particular to a system and method for measuring the attitude of a spinning satellite by using a single-antenna navigation receiver. Background technique [0002] With the continuous development and application of small satellite technology, it has been valued by many countries because of its light weight, small size, low cost, and flexible launch. Compared with the traditional method of using star sensors, sun sensors, and earth horizon sensors to determine the attitude of small satellites, the use of global positioning systems to determine the attitude of small satellites has the characteristics of light weight, high precision, continuity, and no error accumulation over time. The demonstration of a "12th Five-Year" background model project in China includes two tiny spinning satellites. If the traditional navigation receiver method is used to determine its attitude, the vector of the baseline between ea...
