摘要： Methods and apparatus for efficient transmission of data by half-duplex transceivers in satellite communication systems are provided. Time reference for the return link is skewed or time-lagged relative to the time reference for the forward link to reduce the amount of guard time required to separate return link transmission from forward link reception by the half-duplex transceiver of a user terminal. The guard time is determined based on a maximum differential round-trip propagation delay and transition times of the half-duplexer transceiver to switch between transmit and receive modes. In a satellite communication system in which a large number of active user terminals are present in a beam coverage, random time offsets are applied to spread approximately equal traffic loads across the time offsets.

摘要： End-to-end beamforming systems (500) include end-to-end relays (503, 1202, 3403) and ground networks (502) to provide communications to user terminals (517) located in user beam coverage areas (519). The ground segment can include geographically distributed access nodes (515) and a central processing system (505). Return uplink signals (525), transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths (1702) in the end to end relay and are relayed to the ground network. The ground network, using beamformers (513, 531), recovers user data streams transmitted by the user terminals from return downlink signals (527). The ground network, using beamformers (513, 529) generates forward uplink signals (521) from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals (522) that combine to form user beams.

摘要： A system is provided for reducing latency data collection from space-based sensor satellites. A mobile vehicle platform includes a sensor module configured to monitor certain conditions, circumstances, environments and situations occurring on or around, or associated with, the Earth, and to generate sensor data resulting from the monitoring. A relay satellite terminal is configured to execute data communications via a communications channel of a first satellite beam, wherein the data communications are configured to relay the sensor data, via satellites, to respective gateways for forwarding to a central processing facility for one or more of aggregation, processing, analysis and dissemination of the data. The relay satellite terminal is further configured to switch the data communications from the communications channel of the first satellite beam to a communications channel of a second satellite beam based on a position of the relay satellite terminal relative to the first and second satellite beams.
