Problems solved by technology

[0003] In the previous control system tests, there was no published verification method for the digital antenna tracking the ground station. In the actual test system, only a brief verification was carried out, and there were the following deficiencies: 1) The digital antenna tracking ground station It is only a simple calculation at a single moment, and it cannot implement real-time dynamic continuous verification during the entire test process, and

Embodiment Construction

[0049] The remote control system sends the satellite maneuver control command; after the control subsystem receives the maneuver control command, it controls the satellite platform to perform the corresponding attitude maneuver, and sends the actuator information to the dynamics module. At the same time, the control subsystem calculates the pointing angle of the data transmission antenna in real time according to the satellite's orbit, satellite attitude and ground station information, and sends it to the data transmission antenna control module. The data transmission antenna control module drives the data transmission antenna to point to the ground station according to the antenna pointing angle information; the satellite dynamics module receives the actuator information on the satellite, simulates the satellite dynamics, outputs the real satellite attitude and orbit information, and sends them to The digital antenna tracking ground station calculation module; the digital ante...

Abstract

The invention discloses a data transmission antenna tracking ground station test verification system and a method used for spacecraft. According to an orbital position of a satellite, an attitude angle of the satellite and an attitude angle speed which are calculated by received dynamic software, and a directional angle of a data transmission antenna which is calculated by satellite software, a data transmission antenna reverse tracking ground station algorithm is provided, a ground station pointed by the data transmission antenna at this time is calculated, and a longitude and a latitude of the ground station are dynamically displayed on monitoring software in real time. Then, a calculated result is compared with ground station latitude and longitude data bound in the satellite software in advance so that correctness of the data transmission antenna reverse tracking ground station can be continuously and dynamically verified in real time.

Description

technical field [0001] The invention relates to a test and verification method for precise tracking of a ground station by a digital transmission antenna for a spacecraft, which is suitable for the test and verification of a digital transmission antenna for precise tracking of a ground station in the ground test of a spacecraft control system, and belongs to the technical field of spacecraft control system testing. Background technique [0002] The data transmission antenna is one of the important components of the large-scale remote sensing satellite payload system, and its main function is to realize the high-speed downloading of image data to the ground station. In order to effectively ensure high-speed data transmission, the beam of the antenna is narrow, and the energy outside the beam attenuates quickly, so the antenna needs to be accurately pointed to the ground station. In particular, frequent and rapid small-angle maneuvers are required during satellite in-orbit bus...
