Abstract

The invention provides a communication in moving antenna and communication satellite rapid alignment device, method and system, and relates to the technical field of communication and navigation. Thedevice comprises antennas, an intermediate frequency receiver, an array antenna beam scanning module and an alignment processing module. The antennas include a satellite navigation array antenna and acommunication in moving antenna. The intermediate frequency receiver is used for positioning the satellite navigation array antenna through the navigation satellite so as to obtain the antenna carrier position. The array antenna beam scanning module is used for performing digital beam scanning on the navigation satellite. The alignment processing module is used for performing alignment calculation on the communication in moving antenna and the communication satellite according to the antenna carrier position and the digital beam scanning result. Initial alignment of the communication in moving antenna and the communication satellite can be rapidly realized so as to greatly shorten the networking time of the communication in moving terminal equipment.

Description

technical field [0001] The invention relates to the technical field of communication and navigation, in particular to a device, method and system for quickly aligning an antenna in motion with a communication satellite. Background technique [0002] At present, satellite communication generally adopts the modulation method of frequency division multiple access. Therefore, the initial alignment of the antenna in motion to the communication satellite is a two-dimensional search process in the air and frequency domains. There are mainly two methods for its realization, one is the signal self-alignment method based on the communication satellite beacon or broadcast signal reception, and the other is the direct alignment method based on the attitude and orientation of the carrier. [0003] The signal self-alignment method based on communication satellite beacon or broadcast signal reception realizes the space and frequency domain search process of the communication antenna in mot...
