Embodiment Construction

[0036] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0037] As an embodiment, with reference to Fig. 1, make an antenna automatic tracking and staring control device of the present invention. The control unit needs to have the following functions:

[0038] 1) Timely and correctly receive the geographic latitude and longitude information, antenna azimuth and elevation angle information sent by GPS and compass equipment, and store them in the external data storage area;

[0039] 2) Calculate the theoretical values ​​of the antenna's azimuth and elevation angles to the star according to the current geographic latitude and longitude information;

[0040] 3) Calculate the actual tracking angle of the antenna according to the calculated theoretical antenna angle and compass information, and drive the motor to make the difference between the actual antenna angle and the theoretical angle within the set ...

Abstract

A method for controlling antenna to automatically track to satellite includes initializing system and fetching effective data of GPS, calculating theoretical angle requiring to be pointed by pitch angle and position angle of current antenna aligning to satellite, fetching compass data to calculate position difference between current pitch angle and position angle of current antenna and said theoretical angle, setting object rotary speed of current motor and driving antenna to make tracking-operation according to said position difference. The device used for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to antenna control technology, in particular to an antenna automatic tracking and alignment control device and method used on a mobile or stationary platform. Background technique [0002] To realize the "aircraft-satellite-ground" real-time transmission system on the small remote sensing aircraft platform, breakthroughs need to be made in a series of key technical issues. Real-time automatic tracking control of airborne satellite antenna is one of the problems to be solved. The airborne communication system is limited by various conditions such as the volume, weight and power consumption of the platform. In order to ensure the establishment of the data communication link, a high-gain directional antenna must be used. The disturbance of the flying platform and the orbital disturbance of the satellite all have an important impact on the real-time tracking of the airborne antenna, and the gain reduction caused by the deviation of t...
