Abstract: A satellite system may have a constellation of communications satellites that provides services to users with electronic devices such as portable electronic devices and home and office equipment. A network operations center may use gateways to communicate with the satellite constellation. The satellite constellation may include sets of satellites with different orbits such as circular orbits with different inclinations, sets of satellites with elliptic orbits, sets of satellites with circular orbits of different altitudes including low earth orbits, medium earth orbits, and/or geosynchronous orbits, and/or sets of satellites with other orbits. The satellite orbits of the satellites in the satellite constellation may be selected to provide coverage to desired user population concentrations at different locations on the earth without using an excessive number of satellites.

Abstract: A system, method, and device to enable communication between a first and second satellite station and a controller of a mobile platform. The controller includes a processor, a first modem facilitating communication with the first satellite station via a first frequency over a first communication link, and a map of the one or more networks of satellite stations including the second satellite station. The controller utilizes the map of the one or more networks of satellite stations to determine the second satellite station for communicating with the controller. A second modem is coupled to the controller and facilitates communication with the second satellite station via a second frequency over a second communication link, wherein the controller is configured to calculate a time to handoff communication with the mobile communicator from the first communication link to the second communication link.

Abstract: Aspects of this disclosure relate to a segmented receiver for a wireless communication system. The segmented receiver includes a first receiver segment and a second receiver segment configured to receive respective radio frequency signals. The radio frequency signals can be orthogonally polarized. Branch circuits in each receiver segment can provide a radio frequency signal to different mixers. The different mixers can be included in different receiver segments and receive local oscillator signals from independent local oscillators. Each receiver segment can process a different bandwidth of the radio frequency signal. Two different bandwidths of the radio frequency signal can be processed concurrently by different receiver segments.

Abstract: A satellite communication system may be configured to establish multiple different tunnels between a first satellite modem and a second satellite modem in accordance with a protocol. The first satellite modem may receive a packet via a tunnel established in accordance with a different protocol, determine an endpoint identifier corresponding to the tunnel based on information from one or more headers included in the packet, identify one of the multiple different tunnels that corresponds to the tunnel, generate a corresponding packet omitting at least a portion of the information from the one or more headers and comprising at least a portion of data included in a payload of the packet and an information block comprising a tunnel index corresponding to the identified one of the multiple different tunnels, and transmit the corresponding packet to the second satellite modem via the identified one of the multiple different tunnels.

Abstract: This application discloses an adaptive transmission method for satellite communication. First, a receive end determines a redundancy version index; second, the receive end feeds back a redundancy version index signal to a transmit end; then, the transmit end receives the redundancy version index fed back by the receive end, and performs operations such as demodulation and decoding on the redundancy version index signal, to obtain the redundancy version index; and then, the transmit end obtains a corresponding redundancy version combination based on the obtained redundancy version index; and finally, the transmit end selects a proper diversity mode for transmission based on the obtained redundancy version combination.
