[ What is claimed is:] [1.]1. An arrangement for the interruption-proof operation of communications links between satellites in LEO networks, each satellite describing an orbit,characterized in thatseveral links with neighboring satellites (4 to 20 and 42 to 58) located in as well as opposite a satellite movement direction, and laterally in respect to the satellite movement direction, are maintained by a corresponding number of miniaturized optical terminals (28 to 38 and 60 to 82) carried by one of the satellites wherein, independently of the actual orbit type of the network, interruption-proof links are assured by a zero azimuth alignment of telescopes of said terminals coinciding with the tangent of the orbit of the one satellite in combination with their advanced miniaturization, as well as their arrangement on a satellite body and their possibility of coherent detection of light signals and coherent tracking of the impinging direction of light signals,wherein the networks include a LEO network.
