Knapsack emergency satellite communication servo system

Abstract

The invention discloses a knapsack emergency satellite communication servo system. The knapsack emergency satellite communication servo system comprises a knapsack bag, an antenna structure unit and an antenna detection unit; the antenna structure unit is arranged in the knapsack bag; the antenna detection unit is used for installing an antenna seat frame; the antenna structure unit comprises a satellite communication antenna, an antenna seat frame, a feed source assembly supporting part and an antenna operation platform; the antenna operation platform is a mobile carrier of the satellite communication antenna; an antenna operation control unit is arranged in the antenna operation platform; a pitch transmission mechanism and an orientation transmission mechanism are connected with the antenna operation control unit; the antenna operation control unit comprises a microprocessor and a driving circuit; the antenna detection unit comprises an antenna angle position detection unit, a GPS (Global Positioning System) positioning unit, an antenna carrier attitude detection unit and a satellite signal strength detection unit. According to the knapsack emergency satellite communication servo system, the structure is simple, the design is reasonable, the single person bearing can be achieved, the use and the operation are simple and convenient, the using effect is good, the satellite search process can be automatically achieved, the accuracy of the satellite alignment is high, the communication performance is excellent, and the communication guarantee is provided for the emergency disposal.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, in particular to a backpack-type emergency satellite communication satellite communication satellite system. Background technique [0002] With the rapid development of economy and society, there are more and more emergencies in the world, and they are more and more frequent. The emergency response needs to be fast and effective. Because the conventional communication on the spot has been destroyed or paralyzed, the rapid transportation can no longer Arrive at the scene, but the satellite communication is not restricted by the geographical environment, and the piggyback satellite communication earth station (hereinafter referred to as the piggyback station) can be carried by a single person to reach the scene where people can enter, and quickly establish a satellite communication link. In actual application, due to the complex geographical environment of the emergency site, it is ...

AI Technical Summary

Problems solved by technology

To sum up, there is a lack of a backpack-type emergency satellite communication satellite communication system with simple structure, reasonable design, single-person carrying, easy operation, and good use effect, which can automatically complete the star-seeking process, and the accuracy of aligning satellites is relatively high. High, excellent communication performance, providing communication guarantee for emergency disposal
