Abstract

The invention discloses an autonomous safety control method for space optical relative measurement equipment. The method comprises the steps: S1, determining the relative position of the sun on an operation orbit plane of space optical relative measurement equipment, and representing the relative position through a sun plane interior angle; S2, calculating an included angle between the optical axis of the space optics relative measurement equipment and the solar plane interior angle in the S1, and representing the included angle as a solar incident angle; and S3, executing a corresponding modestate according to a size relationship between the solar incident angle and the solar protection angle threshold of the space optics relative measurement equipment. The method has the advantages thatthe relation among the solar surface interior angle, the solar incident angle and the solar protection angle threshold value is reasonably utilized, the on-orbit operation safety work requirement ofthe space relative measurement equipment is met, the method is clear in principle, convenient to implement and suitable for on-orbit work, and the work safety of the space relative measurement equipment can be guaranteed.

Description

technical field [0001] The invention relates to the field of safe operation of space orbits, in particular to an autonomous safety control method for space optical relative measuring equipment, so as to ensure product safety during orbital operation. Background technique [0002] New requirements such as binary star formation, satellite constellation, and space security have promoted the development of inter-satellite relative measurement technology. A variety of inter-satellite relative measurement products, such as microwave radar, photoelectric combination, and laser radar, are emerging and have been successfully used in orbit. [0003] Usually space optical relative measurement equipment includes photoelectric combination, binocular camera and other products with optical camera as the main body. Due to its detection system, the most important influence of the camera during its work in space is the sun. Space cameras have an important indicator: the sun protection angle...
