Abstract

The invention discloses a mobile satellite communication antenna terminal with an anti-interference positioning function. The mobile satellite communication antenna terminal comprises a directional transceiving antenna, an IMU or INS module, a GNSS module (optional), an antenna control module, a Doppler frequency shift tracking module, a position state estimation module, a satellite communication module and the like. The directional transceiving antenna forms a directional beam to transmit and receive satellite communication signals. The IMU or INS module obtains attitude information of the motion carrier; the antenna control module controls an antenna beam to align with a communication satellite; the Doppler frequency shift tracking module performs Doppler frequency shift tracking on satellite communication signal carriers or beacons; and the position state estimation module is used for fusing various information and outputting high-precision position information of the moving carrier. According to the mobile satellite communication antenna terminal, when the GNSS module does not exist or the GNSS signal is interfered, the satellite communication function and the moving carrier positioning function of the mobile satellite communication antenna terminal can work normally.

Description

technical field [0001] The invention belongs to the technical field of satellite communication terminals, in particular to a mobile satellite communication antenna terminal with an anti-interference positioning function. Background technique [0002] The traditional mobile satellite communication antenna terminal needs to rely on GNSS equipment to provide the position information of the moving carrier, so that the antenna can point to the satellite satellite, and then assist in the realization of the beam pointing control between the carrier and the satellite. When GNSS is interfered, it is difficult for the satellite communication system to work normally. [0003] In the face of complex modern battlefield environment conditions, GNSS information is susceptible to interference, which causes the movement carrier satellite communication measurement and control system to fail to work normally, resulting in communication interruption. [0004] The applicant submitted a Chinese ...
