Problems solved by technology

[0004] Although the antenna can monitor and control the satellite along the established orbit, it cannot ensure that the antenna can completely keep up with the satellite. If the antenna moves too fast or too slow, it cannot be completely aligned with the satellite, resulting in insufficient signal acquisition, which will affect the effect of measurement and control.

Embodiment Construction

[0040] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0041] As the first embodiment of the present invention, a satellite measurement and control station is provided, such as figure 1 As shown, antenna 200, turntable 100, base 300, and integrated system 400 are included. The antenna 200 is fixed above the turntable 100 for signal transmission with the satellite. The turntable 100 is used to drive the antenna 200 to rotate, so that the antenna 200 moves according to a predetermined movement track. The base 300 is fixed below the turntable 100 for supporting the turntable 100 and the antenna 200 . The integrated system 400 is used for signal transmission and system control.

[0042] like figure 1 As shown, the antenna 200 includes a parabolic reflector and a feed.

[0043] like figure 2 and image 3As shown, the turntable 100 includes a base 1, a connecting fra...

Abstract

The invention relates to the technical field of satellite measurement and control, and provides a method for correcting the movement deviation of a satellite on a moving orbit and a satellite measurement and control station. The method includes: acquiring the moving orbit of an antenna; the antenna starts to track the satellite at a first moving speed, and every predetermined time Obtain the current signal strength of the antenna; according to the difference between the current signal strength and the last signal strength, determine whether the position of the antenna is deviated from the satellite motion, and if so, adjust the motion speed of the antenna accordingly. This solution can realize that the antenna is aligned with the satellite, obtain a strong communication signal, and improve the effect of measurement and control.

Description

technical field [0001] The invention relates to the technical field of satellite measurement and control, in particular to a method for correcting the movement deviation of an antenna on a moving orbit and a satellite measurement and control station. Background technique [0002] The task of the measurement and control station is to directly perform tracking measurement, telemetry, remote control and communication on the spacecraft. It transmits the received measurement and telemetry information to the aerospace control center, communicates with the spacecraft according to the instructions of the aerospace control center, and cooperates with the control center. Complete control of the spacecraft. [0003] The antenna of the existing measurement and control station sets the movement orbit of the antenna before the arrival of the satellite, and when the satellite enters the measurement and control range, the movement of the antenna is controlled according to the movement orbit...
