Abstract

To help China's first Mars mission go smoothly and improve the performance of the solar cells mounted on the rover in illumination conditions on the Martian surface, the project team launched a study to simulate the sky light on the Martian surface.This paper focuses on the influence of Martian sky light on solar array output at different solar elevation angles and light depths.Based on the approximate model of sky light radiation, a set of sky light simulation equipment on the surface of Mars is developed.The advantages and disadvantages of using LED light source and metal halide light source to simulate sky light are compared and analyzed.The sky light simulator can simulate the sky light with the solar elevation Angle of 75°, 60° and 45°, and the sky light with the optical depth of 0.9, 0.7 and 0.2.According to the requirements of the test department, the simulation effect was tested with instruments such as spectrometer.The test results were approved by the test department, and the skylight simulator has been applied to subsequent Mars rover tests.
