In order to ensure propagation between satellites in the least possible time, a broadband service articulated around constellations of satellites with inter‐satellite laser links (ISLs) is considered. This technology makes it possible to satisfy the increasing demand for data traffic. This chapter seeks to establish effective inter‐satellite links to increase the performances of the laser beams that reduce propagation delays, and to filter communication to avoid any form of interference. It considers low earth orbit (LEO) satellite constellations' ISLs for reduce inter‐satellite propagation delays. There are two types of ISL connections: intra‐orbit ISLs and inter‐orbit ISLs. The first type of connection connects satellites that belong to the same orbital plane, so the relative distance of the two communicating satellites is fixed, no Doppler effect can be detected, while the second type of connection connects satellites belonging to different orbital planes.
