A fast switching kaku dual-band portable satellite earth station

Abstract

The present invention provides a fast switching kaku dual-band portable satellite earth station. The fast switching kaku dual-band portable satellite earth station includes a general component and a feed component, the feed component is electrically connected with the general component, and the feed The components include ka feed components and ku feed components. The general component automatically identifies the type of feed component according to the signal from the feed component. The general component switches to the frequency band corresponding to the type of the feed component. The feed component communicates with the satellite and communicates with the satellite. The satellite signal is sent to the general component, and the general component controls the feed component to find and align the satellite and receive the satellite signal through the feed component. The advantages of this system and method are: the ka feed component and the ku feed component can be easily replaced; the type of feed can be identified and automatically switched between the ka frequency band and the ku frequency band according to the type of feed, and the switching speed is fast; Components other than the source assembly can be generalized and the equipment cost is low.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to a fast switching kaku dual-band portable satellite earth station. Background technique [0002] Ka-band and Ku-band are two frequency bands that are now frequently used for satellite communications. The general frequency range of the Ka frequency band is 18.7GHz to 30.0GHz. This frequency band has the characteristics of available bandwidth and very small equipment volume. Therefore, the Ka-band satellite communication system can provide a new means for new services such as high-speed satellite communication, gigabit-level broadband digital transmission, high-definition television (HDTV), satellite news gathering (SNG) and personal satellite communication. The disadvantage of the Ka frequency band is that the rain attenuation is relatively large, and the requirements for devices and processes are relatively high. [0003] The frequency of the Ku-band is generally 10.95-14....

AI Technical Summary

Problems solved by technology

The communication rate, stability, safety and reliability are important means to measure the quality of satellite communication. Judging from the characteristics of ka and ku, single-band satellite communication methods cannot meet the current use of emergency communications in various complex environments. Dual-band satellite portable communication The device can effectively solve the problem

[0005] At present, single-band satellite stations are mainly used at home and abroad, and there are also dual-band satellite stations, but users cannot switch freely on site. They need to carry tools and many accessories on site, which are large in size and very inconvenient to carry. Tools are required to replace hardware and structure at the same time. The software also needs to be replaced (the general system software requires on-site or remote support from the manufacturer), the time is long, the operation is complicated, etc., which cannot meet the existing emergency rescue needs, and non-professionals cannot complete the entire operation alone on site.
