Control device and method for automatic star-seeking and network access of closed-loop ip-star satellite mobile station

Abstract

The invention relates to an automatic satellite search and network access control device and method for a closed-loop IP-star satellite mobile station. According to the connection relation of all components of the device, a satellite antenna system is connected with a power amplifier and a downlink L wave band frequency converter; the downlink L wave band frequency converter is connected with a frequency selection module and a tracking receiver through a shunt; the tracking receiver and a user side are connected in an information two-way feedback mode; the frequency selection module is connected with the shunt, the user side and a modem; the modem is connected with the power amplifier, the frequency selection module and the user side; the power amplifier is connected with the user side and the satellite antenna system. The method includes the steps that a power supply of the satellite mobile station is turned on; positioning is achieved through a GPS chip; the tracking receiver determines the spot beam where the satellite mobile station is located; the user side receives, analyzes and processes information of the spot beam; a satellite antenna servo mechanism instructs a satellite antenna to automatically search for a satellite; the modem has access to a network according to the information; network access succeeds. The automatic satellite search and network access control device and method are low in running cost and high in practicability.

Description

technical field [0001] The present invention relates to a control device for automatic star-seeking and network access of a closed-loop IP-star satellite mobile station. It is a control device for automatic star-finding and network access through a satellite antenna and a servo control system. A control method for equipment belongs to the technical field of satellite communication. Background technique [0002] The IP-star broadband satellite communication system adopts KA+KU composite transmission technology and frequency multiplexing technology, so that the cost of satellite transponders is much lower than that of traditional satellites. It not only has a strong competitive advantage in traditional satellite communication services, but also has broadband access The cost is almost comparable to that of the terrestrial broadband network; not only can it provide domestic users with integrated services including Internet broadband access, voice, data, video and multimedia, but...

AI Technical Summary

Problems solved by technology

[0003] IP-star satellites have 23 spot beams covering eastern China, one broadcasting beam, and one shaped beam covering western China. The main communication resources are in 23 spot beams. For fixed satellite stations, there is no need to cross regions, and they can be used in Normal communication in one spot beam, but for the satellite mobile station, it needs to work in different spot beams across regions, and the link needs to be re-established across spot beams. If the link is manually established, it will take a long time, so the mobile station cannot be realized. ZTO, the application is greatly restricted
