Abstract

The present application relates to the technical field of space laser communications. Disclosed are a signal light sending method and apparatus, a signal light receiving method and apparatus, and a device and a medium. The method comprises: a sending satellite determining, on the basis of an inter-satellite link margin, the number of array groups matching the inter-satellite link margin, wherein the inter-satellite link margin represents the link quality between the sending satellite and a receiving satellite; on the basis of the number of array groups, grouping a micro-electro-mechanical system (MEMS) array to obtain M MEMS sub-arrays, M being an integer greater than 1; and if a first divergence angle of the M MEMS sub-arrays is greater than the radian of a receiving area of the receiving satellite, controlling the M MEMS sub-arrays to send signal light to the receiving satellite at the first divergence angle, wherein the receiving area is an area formed by means of the location of the receiving satellite and an error range of the location.
