Abstract

The invention discloses a satellite communication in motion rapid capturing method; the method comprises the following steps of 1, performing system initializing; 2, establishing a coordinate system;3, carrying out pre-adjustment of antenna pointing; 4, carrying out coarse capture of an antenna; and 5, carrying out accurate alignment of the antenna. The method is simple in steps, reasonable in design and convenient to implement, and pre-adjustment of antenna pointing is realized by utilizing the position and speed information of a carrier detected by a GPS module, so that the target communication satellite can be rapidly captured under different motion states of the carrier, the accurate alignment of the antenna and the target communication satellite is realized, the capture and fine alignment time is short, the stability of the antenna relative to the inertial space is ensured, the rapid response capability of the communication in motion system is improved, and the method is high inpracticability.

Description

technical field [0001] The invention belongs to the technical field of mobile satellite communication, and in particular relates to a dynamic and fast capturing method of satellite communication in motion. Background technique [0002] With the development of economic globalization and informatization, people urgently need to be able to transmit or receive broadband, large-capacity voice, data, images, video and other multimedia information in real time at any place and any time during the journey, so that faster and faster Accurately grasp the rapidly changing situation. Satellite communication is the only communication system that can provide different business requirements in different environments at the same time. Because the bandwidth allocated to satellite mobile services by the International Telecommunication Union is low, it is difficult to meet the needs of broadband communication services. The "communication in motion" communication system based on the fixed sat...
