Abstract

The invention discloses an adaptive combination navigation antenna beam control method for a satellite communication in motion communication system. The method comprises the following steps: (1) building a system equation of the satellite communication in motion system, calculating the state variable x of a combination navigation attitude estimation system according to the position error amount deltar of a carrier, the speed error amount deltav of the carrier and the attitude angle error amount Psi of the carrier, and meanwhile setting the observed quantity of a satellite communication in motion combination navigation attitude estimation algorithm with a main controller; (2) building a corresponding satellite communication in motion combination navigation measurement equation according to different driving environments of the carrier, and solving a measurement equation coefficient matrix Hk; and (3) performing attitude computation through adaptive extended Kalman filter to obtain the three-dimensional attitude angle of the carrier, and controlling three motors to adjust the direction of antenna beams according to the three-dimensional attitude angle of the carrier in order that an antenna is aligned with a satellite. Through implementation of the method, accurate alignment between the antenna and the satellite can be realized, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of satellite communication system antenna beam control, and relates to an antenna beam control method, in particular to an adaptive combined navigation antenna beam control method for a satellite communication system in motion. Background technique [0002] With the advent of the information age and the rapid development of the new military revolution, people's demand for communication is increasing, and people urgently need to realize high-speed, high-bandwidth communication in mobile. However, the limited frequency band resources of mobile satellite communication, slow communication rate and high service cost seriously restrict the further development of mobile communication, which greatly stimulates the development of a new type of satellite communication terminal - Mobile Communication. Communication in motion is an important branch of satellite communication. It aims to use fixed satellite communication...
