Abstract

The invention discloses a self-adaptive communication method and system for links among micro-nano satellite groups, belongs to the technical field of communication among micro-nano satellite groups, and aims to solve the problem of low communication efficiency or data loss caused by the fact that the communication rate cannot be dynamically adjusted in the conventional inter-satellite link communication method. The method is technically characterized by comprising the following steps of: establishing an inter-satellite link communication channel knowledge base according to an inter-satellite link communication error rate threshold value requirement of a micro-nano satellite group; according to the real-time communication distance between the two micro-nano satellites, selecting the maximum communication rate value as the optimal communication rate value, and selecting the corresponding coding modulation scheme as the optimal coding modulation scheme; and carrying out coding and modulation processing on inter-satellite communication data according to the optimal coding modulation scheme, and carrying out inter-satellite link communication according to the optimal communication rate value. According to the method, high-efficiency and reliable transmission of telemetry data is realized, and the method is of great significance in improving self-adaptive signal processing of inter-satellite links of a micro-nano satellite group system.

Description

technical field

[0001] The invention relates to the technical field of micro-nano-satellite inter-satellite communication, in particular to a micro-nano-satellite inter-satellite link adaptive communication method and system. Background technique

[0002] During the inter-satellite communication process of the micro-nano constellation, the inter-satellite distance continues to change. If the inter-satellite link communication communicates at a single communication rate, it will cause low communication efficiency or data loss. Then, how to make the inter-satellite communication reliable and effective for different inter-satellite communication distances, so as to realize the reliable high-speed communication of the micro-nano constellation system, is an urgent problem to be studied and solved. Contents of the invention

[0003] In view of the above problems, the present invention proposes a self-adaptive communication method and system for inter-satellite links of micro-nan...
