Overview, problems and suggestions of inter satellite link in LEO communication constellationTime of issue : 2018 - 09-04
Inter satellite link refers to the communication link established between satellites, also known as interstellar link or cross link. The inter satellite link can realize the information transmission and exchange between satellites. Multiple satellites can be connected together, and become a space communication network with satellites as switching nodes, which reduces the dependence of satellite communication system on ground network. With the advantages of inter satellite links, communication system can reduce the number of ground station settings, expand coverage area, realize global measurement and control, etc., and the attenuation caused by atmosphere and rain can be avoided effectively when the signal is transmitted in the inter satellite link, and a relatively independent communication constellation system or data relay system will be formed.
