Embodiment Construction

[0020] Please refer to the accompanying drawings for further description of the present invention.

[0021] like figure 1 As shown, the present invention is a portable satellite communication system that can adjust the antenna azimuth, pitch, polarization, etc. to the vicinity of the correct satellite azimuth in the shortest time, so as to prepare for the next fine-tuning satellite search, and at the same time try to ensure that the terrain, Even if the weather, bearing accuracy and other factors are not ideal, the star finding task can also be completed, and factors such as the compatible search range of the coarse search method must also be considered.

[0022] The invention provides a method for searching and tracking satellites. The steps of the method are: 1. Roughly adjust the search method:

[0023] A. First, search within 10 degrees of horizontal azimuth under the condition that the antenna elevation angle remains unchanged;

[0024] B. The motor that controls the ho...

Abstract

A method of searching and tracking the satellite, comprises three steps: a coarse adjustment searching method, a fine adjustment searching method and a tracking locking method. After a satellite orientation is coarsely found, through the coarse adjustment searching method, correct and fast satellite calibration is performed through the fine adjustment searching method, the satellite signal which has been found is tracked and locked, ensuring the signal without larger change after long time working. The invention has the advantages that, not only the general satellite searching is performed, but also it is convenient for the users to carry over a portable satellite communication system for normal working in foul topoclimate, and the invention is characterized in quick speed, accuracy and stability.

Description

technical field [0001] The present invention relates to a method for enabling a portable satellite communication system to quickly search and locate satellites, as well as search and track satellites for interactive communication in any outdoor environment. Background technique [0002] At present, there is no method that can calculate and quickly and accurately determine the location of equipment and satellites through GPS azimuth information in any outdoor environment. It can quickly and accurately find stars, locate, track, and communicate. Change the finder target and the communication frequency. SUMMARY OF THE INVENTION [0003] The technical problem of the present invention is to provide a method for searching and tracking satellites that can quickly search for the position of satellites and finally lock the signal strength of the satellites. [0004] In order to solve the above technical problems, the present invention provides a method for searching and tracking s...
