A system comprising an accelerator including a first physical port couplable to a first module and a second physical port configured to communicate with a wide-area network. The accelerator is programmed to receive outbound data from user devices via the first module, and route the outbound data to either the first physical port or the second physical port. The first module is a separate unit from the accelerator. The first module includes an indoor unit configured for satellite internet.

Methods and systems are described for providing end-to-end beamforming. For example, an end-to-end beamforming system include a relay satellite and a ground network to provide communications to user terminals located in user beam coverage areas. The ground network includes geographically distributed access nodes and a central processing system (CPS). Beamformers of the ground network generate forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the satellite, produce forward downlink signals that combine to form forward user beams.

For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.

A method of space communication for IoT or equivalent services increases the number of terminals served on a space transmission resource while limiting the signaling used by the terminal. This limitation is obtained on the one hand by the allotting to each terminal of a logical beam, corresponding to a predetermined fixed geographical area wherein the terminal lies. This limitation is obtained on the other hand by management, centralized at the level of a central entity for connecting to the space network, of the association of the terminal with a logical beam and of the association of the resources bound for the logical attachment beam. A space telecommunications system implements a method of space communication. The method of space communication allows transparent switchover from a terrestrial system to the space system when the terrestrial system and the space system are integrated to a high degree, particularly at the level of the terminal.

In an exemplary embodiment, a phased array antenna comprises multiple subcircuits in communication with multiple radiating elements. The radio frequency signals are independently adjusted for both polarization control and beam steering.

In a transmit embodiment, at least one transmit beam input is divided and transmitted through multiple radiating elements, with the transmitted beams having various polarizations. In an exemplary embodiment, the phased array antenna provides multi-beam formation over multiple operating frequency bands. The wideband nature of the active components allows for operation over multiple frequency bands simultaneously.

A high data rate distribution network for low-earth orbit (LEO) satellite constellations is described. The high data rate distribution network includes multiple LEO constellations, each constellation including a number of LEO spacecraft orbiting in a LEO plane that are all connected together by by-directional free space optical links. The distribution network further includes geostationary earth orbit (GEO) spacecraft in communication with a number of ground gateways. The GEO spacecraft can receive forward communication traffic including radio-frequency (RF) and/or optical data streams uplinked from the ground gateways and can convert the received forward communication traffic into a forward aggregated traffic. The GEO spacecraft can further optically downlink the forward aggregated traffic to LEO spacecraft in a LEO constellation that is in line of sight of the GEO spacecraft. The forward aggregated traffic is then disaggregated among and received by the LEO spacecraft in the LEO constellation. Return communication traffic from each LEO spacecraft can also be aggregated into a return aggregated traffic from the LEO constellation. The return aggregated traffic is optically uplinked to a GEO spacecraft by a LEO spacecraft of the LEO constellation that is in line of sight of the GEO spacecraft. The GEO spacecraft converts the received return aggregate traffic into multiple RF and/or optical data streams that are down linked to a number of ground gateways.
