Embodiment

[0036] In order to test the pointing accuracy of the satellite two-dimensional rotating spot beam antenna, the present invention uses two sets of different algorithms of satellite antenna servo software and ground test system to calculate the angle, and uses the ground two-dimensional pointing mechanism to feed back real angle information, and finally performs angle comparison. Get the pointing error.

Abstract

The invention provides a system and method for measuring the pointing accuracy of a satellite two-dimensional rotating spot beam antenna, including: a GPS simulator: used to recursively generate satellite orbit parameters and output them to an attitude and orbit control subsystem; an attitude and orbit control subsystem: receive After the orbit parameters, the ephemeris is calculated and broadcast; the mechanism drive controller: drives the ground two-dimensional pointing mechanism simulator to rotate; the ground two-dimensional pointing mechanism simulator: feeds back the angle information of the mechanism rotation to the mechanism drive controller; measurement and control subsystem : It is composed of the attitude and orbit control subsystem and the mechanism drive controller, and sends the telemetry information to the ground test system; the ground test system: monitors the telemetry information, carries out the simulation calculation of the theoretical angle of the antenna, and calculates the angle with the satellite servo stand-alone computer, and The rotation angle of the mechanism simulator is compared for errors, and the pointing accuracy test results are obtained. The satellite antenna of the present invention does not need to be installed with satellites, the system and the test method can cover any orbit and reduce the test condition requirements.

Description

technical field [0001] The invention relates to the technical field of engineering measurement, in particular to a system and method for measuring the pointing accuracy of a satellite two-dimensional rotating spot beam antenna. Background technique [0002] In the satellite data communication system, the antenna is an important component for transmitting data with the ground station and with other satellites. Due to the high gain, the two-dimensional spot beam antenna has the functions of tracking servo and precise pointing, which can realize data transmission at a large data rate, and has been widely used and vigorously developed in satellite communication systems all over the world. [0003] When the satellite communicates with the ground station or other satellites, it is necessary to keep the spot beam antenna accurately pointing to the target of the other party. Therefore, the pointing accuracy of the spot beam antenna is an important indicator of the satellite antenna,...
