Embodiment 1

[0016] The three-diversity anti-jamming satellite navigation receiver of this embodiment includes three anti-jamming antenna groups and a three-diversity satellite navigation receiver. The three anti-jamming antenna groups convert the received satellite signals into digital signals, and after anti-jamming calculations eliminate the interference signals, they are restored to radio frequency signal output. The three-diversity satellite navigation receiver receives the satellite signals output by the three anti-jamming satellite antennas for signal capture and tracking respectively, obtains the original observation information of all satellites of the three signals, and integrates the three satellite information for positioning. When the carrier is maneuvering at high speed, only one of the three antennas arranged at different positions of the carrier can receive satellite signals to provide positioning data. The specific structure and working process are described as follows:

Abstract

The invention relates to a three-diversity anti-interference satellite navigation receiver, which comprises an anti-interference antenna group, a three-diversity satellite navigation receiver, a satellite signal capturing / tracking unit and a positioning information fusion unit, and is characterized in that the three-diversity satellite navigation receiver is used for receiving three paths of satellite navigation signals of the anti-interference antenna group; the satellite signal capturing / tracking unit is used for performing satellite navigation signal capturing on the three paths of satellite navigation signals, and acquiring original observation information of all satellites of each path of navigation signals; and the positioning information fusion unit is used for fusing the original observation information of all satellites of the three paths of signals, and positioning and calculating positioning information according to the original observation information of the satellites. The three-diversity anti-interference satellite navigation receiver receives signals outputted by three anti-interference satellite antennas simultaneously and performs information fusion on the three signals, so that use requirements of a ballistic missile, especially a whole-course maneuvering ballistic missile, in complex electromagnetic environmental conditions are met.

Description

Technical field [0001] The invention relates to satellite navigation reception, in particular to a three-diversity anti-jamming satellite navigation receiver, which is used in the field of military satellite navigation with high anti-jamming capability, high precision, and requirements for rapid changes in carrier attitude. Background technique [0002] Satellite navigation receivers have a wide range of applications in both civil and military fields. Civilian applications are basically concentrated in low-speed and low-mobility fields. In the military field, carrier rockets and ballistic missiles require satellite navigation receivers with high anti-jamming capabilities, high precision, and ability to adapt to rapid changes in carrier attitudes. Civil satellite navigation receivers and ordinary high-precision military satellite navigation receivers cannot meet the requirements. Summary of the invention [0003] The purpose of the present invention is to overcome the above shortco...
