Abstract

The invention discloses a satellite positioning method and apparatus. The method comprises the following steps: a receiver receiving satellite signals sent by multiple navigation satellites through an antenna array, and generating a satellite signal matrix; according to the satellite signal matrix, obtaining a first output signal sequence, performing synthesis operation on the first output signal sequence to obtain a first synthesis satellite signal sequence, and according to the first synthesis satellite signal sequence, carrying out positioning; in case that the positioning fails, according to the satellite signal matrix, obtaining a second output signal sequence through a self-adaptive zeroing algorithm, and according to the first output signal sequence and the second output signal sequence, carrying out synthesis operation on the received satellite signals sent by the multiple navigation satellites to obtain a second synthesis satellite signal sequence; and according to the second synthesis satellite signal sequence, carrying out the positioning. According to the invention, the technical problem of poor anti-interference capability in satellite positioning is solved.

Description

technical field [0001] The present invention relates to the field of satellite positioning, in particular to a satellite positioning method and device. Background technique [0002] After years of development of satellite navigation technology, a satellite navigation system represented by the GPS system of the United States, the GLONASS system of Russia and the Beidou navigation and positioning system of my country has been formed. However, the ground satellite signal is very weak, and a small interference signal can affect the receiver's reception of the satellite signal, making it unable to work and locate normally. Therefore, it is necessary to suppress unintentional or intentional interference. Satellite navigation adaptive anti-jamming array suppresses jamming signals through spatial filtering, which is a technology that has been studied more and has entered practical applications. [0003] Spatial filtering mainly includes adaptive zeroing technology and beamforming ...
