Embodiment 1

[0016] The three-diversity anti-jamming satellite navigation receiver in this embodiment includes: three anti-jamming antenna groups and the three-diversity satellite navigation receiver. The three anti-jamming antenna groups convert the received satellite signal into a digital signal, and after the anti-jamming calculation eliminates the jamming signal, it restores it to a radio frequency signal output. The three-diversity satellite navigation receiver receives the satellite signals output by the three-way anti-jamming satellite antenna for signal acquisition and tracking respectively, obtains the original observation information of all satellites of the three-way signals, and fuses the three-way satellite information for positioning. When the carrier maneuvers at high speed, as long as one of the three antennas arranged in different positions of the carrier can receive satellite signals, it can provide positioning data. The specific structure and working process are describe...

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 ability, high precision, and adapting to the requirements of rapid changes in carrier attitude. Background technique [0002] Satellite navigation receivers are widely used in both civilian and military fields, and the applications in the civilian field are basically concentrated in low-speed and low-mobility fields. Carrier rockets and ballistic missiles in the military field require satellite navigation receivers to have high anti-interference ability, high precision, and adapt to sharp changes in carrier attitude. Civilian satellite navigation receivers and ordinary high-precision military satellite navigation receivers cannot meet the requirements. Contents of the invention [0003] The purpose of the present invention is to overco...
