Abstract

Aiming at the three-axis stabilized geosynchronous orbit (GEO) satellites, a satellite working state detection method based on the photometric reflection characteristics is proposed. Firstly, the characteristics of the bidirectional reflection distribution function of the commonly used materials on satellite are analyzed. The amplitude variation characteristics and the beam widths of the specular reflection of the materials are discussed based on one modified Phong BRDF model. Secondly, the GEO satellite photometric observation equations are analyzed. The photometric characteristics of the satellites caused by solar motion and the duration of the satellite specular reflection under normal working conditions were quantitatively analyzed and the duration is then put forward as a quantitative judgment basis for working state of GEO satellite. Finally, Simulation results indicate that the detection method under the criteria we proposed can accurately determine whether the satellite is working normally or not. The method proposed can be used as a basis for detecting the working state of GEO satellites quickly which could be useful for space situation awareness.
