Abstract

The invention discloses a sun vector determination method and device, a computer readable storage medium and a processor. The method comprises the following steps: acquiring sun time and fixed star time at a target position on a celestial body; determining the right ascension and declination of the target position according to the sun time and the fixed star time; according to the right ascension and the declination, determining a first sun vector representing the sun direction in a celestial body coordinate system, wherein the celestial body coordinate system is a coordinate system established with a celestial body as an original point; according to the first sun vector, determining a second sun vector representing the sun direction in a local coordinate system, wherein the local coordinate system is a coordinate system established with the target position as the original point. The technical problem that the process of obtaining the sun vector at the target position on the celestial body is tedious and complex is solved.

Description

technical field [0001] The present invention relates to the field of aerospace, in particular to a sun vector determination method, device, computer-readable storage medium and processor. Background technique [0002] In the field of aerospace measurement and control and remote operation of extraterrestrial celestial bodies, it is necessary to determine the sun orientation at a specific position on the celestial body, and provide ground personnel with a basis for decision-making and control. However, there are the following technical problems in the related technology: firstly, it is inconvenient to use the earth time for calculation and processing, which makes it inconvenient to carry out repeated planning based on the cycle of the week on the surface of an extraterrestrial celestial body. Secondly, using the astronomical ephemeris to perform calculations based on the relative positional relationship between the sun and celestial bodies requires a large amount of calculatio...
