The invention provides a method and a device for detecting rotation of satellite solar panels. The method comprises steps as follows: telemetry data of a satellite in a default mode is acquired and comprises solar ephemeris data under an orbital coordinate system and driving data of a dual-shaft solar panel driving mechanism; theoretical orientation of the solar panels is determined according to the solar ephemeris data under the orbital coordinate system, and a theoretical rotating direction of the dual-shaft solar panel driving mechanism is determined according to the driving data of the dual-shaft solar panel driving mechanism; whether the rotating direction of the solar panels is corrected is detected according to the theoretical orientation of the solar panels, the theoretical rotating direction of the dual-shaft solar panel driving mechanism, current real orientation of the solar panels and a current real rotating direction of the dual-shaft solar panel driving mechanism. According to the method and the device, whether the rotation of the solar panels driven by the dual-shaft solar panel driving mechanism is correct can be detected, and besides, the orientation of the solar panel and the rotating direction of the dual-shaft solar panel driving mechanism can be detected, so that a detection result is relatively accurate.
Description
technical field [0001] The invention relates to the technical field of satellite testing, in particular to a method and device for detecting the rotation of a satellite sailboard. Background technique [0002] The sailboard of the satellite is covered with solar cells. When the satellite is flying in orbit, the sailboard tracks the sun and obtains solar energy, and converts the solar energy into electrical energy as the energy supply for the satellite. In order to enable the sailboard to obtain solar energy, the sailboard points to the sun in real time when the satellite is flying. In order to ensure that the sailboard can point to the sun in real time, it is necessary to detect the pointing of the sailboard and the change trend of the pointing. [0003] In recent years, due to new missions and new requirements, satellites often need to fly in non-sun-synchronous orbits. The range of solar altitude angles in non-sun-synchronous orbits is very wide, and the maximum can reach ...
