A microwave switching device comprises: a switching matrix with M inputs and N outputs comprising at least one surface-mount microwave switch with ohmic contacts with at least one input and at least one output position; a control bus for the one or more microwave switches of the switching matrix; a telemetry bus for the M inputs; a telemetry bus for the N outputs; a bias tee positioned on each input of the switching matrix; and a bias tee positioned on each output of the switching matrix.

An inter-satellite communication device for satellites orbiting within a constellation of satellites comprises at least one optical terminal dedicated to intra-orbital plane communication links and at least one optical terminal dedicated to inter-orbital plane communication links, each optical terminal dedicated to intra-orbital plane communications configured to transmit and receive optical signals with an optical terminal of an identical satellite orbiting in the same orbital plane, each optical terminal dedicated to inter-orbital plane communications configured to transmit and receive optical signals with an optical terminal of an identical satellite in an orbital plane adjacent over the entirety of its orbit in its orbital plane and each optical terminal dedicated to inter-orbital plane communications having a field of regard such that the half-angle at the vertex of the latter is larger than the maximum value of the azimuthal angle over a revolution around the Earth.

A system comprises a constellation of satellites placed in non-geostationary orbit, user terminals located in a coverage area, and N anchor stations able to ensure bidirectional communications with the user terminals by way of at least one satellite. The system furthermore comprises a network of routers interconnected with one another and to the Worldwide Internet Network, each anchor station is connected to the Worldwide Internet Network by way of a router, and each anchor station comprises a management device for managing the handovers to ensure service continuity for the communications. This management device is able to control the handovers between the successive orbiting satellites progressing over the coverage area, the handovers between anchor stations, or the handovers between simultaneously successive satellites and anchor stations.
