Description

technical field

[0001] The present application relates to the technical field of satellite solar panels, and in particular, to a method for designing a solar panel device for a solar synchronous orbit satellite and a solar panel device designed by using the method. Background technique

[0002] The solar panel part of the existing sun-synchronous orbit satellite adopts a single-axis SADA (solar panel drive mechanism) and the SADA rotation axis is perpendicular to the solar panel method, and the attitude control system of the satellite can be used to achieve sun orientation.

[0003] Existing solar panels need to use a solar panel servo system, so that the solar array always points to the sun, and the load points to the direction of the mission, so as to ensure sufficient energy for the satellite system under the condition of uninterrupted mission. Most of the existing single-axis windsurfing drive devices use motor servo systems, including stepper motors, reducers, and servo...
