Abstract: A satellite system controller for a satellite system can comprise a receiving module, an interval selector, an epoch selector, and a scheduler. The receiving module can receive, from a transmission originator device, a set interval request message requesting the satellite system controller set a transmission interval and an epoch time for a satellite receiver, the transmission interval being an amount of time the satellite receiver is to remain in a sleep mode between expected transmissions and the epoch time being an instant at which the satellite receiver is to expect a satellite transmission. The interval selector can determine, based on the transmission interval, a sleep mode cycle for the satellite receiver. The epoch selector can select the epoch time according to the sleep mode cycle and the scheduler can schedule the satellite transmission with the satellite system at approximately the epoch time and according to the sleep mode cycle.

Abstract: A system, various methods, and a specific apparatus are provided for the purpose of supporting push-to-talk (PTT) service for a very large group featuring a significantly higher number of listeners than the number of potential talkers, as well as a constrained vocabulary in normal usage. The invention takes advantage of speech-to-text and text-to-speech conversion in end user devices for maximum utterance compression. The invention uses the Iridium Mobile Satellite Service (MSS) system and its Short Burst Data (SBD) service for unicast transmission of talker utterances to a PTT Server, and the same system's Global Data Broadcast (GDB) service for multicast retransmission of utterances from the PTT Server to an effectively unlimited number of listeners. The PTT Server provides priority ordering and preemption as necessary when multiple talkers provide near-simultaneous utterances, effectively managing the floor without interactive protocols among the talkers.

Abstract: A method of scheduling a transmission with a multi-beam satellite system receives, at a dynamic pricer, a request parameter that is associated with a request to transmit data via a multi-beam satellite system. The method determines a plurality of transmission solutions that satisfy the request parameter. The plurality of transmission solutions are transmitted, from the dynamic pricer, to a transmission requesting device. An indication is received, at the dynamic pricer, as to which particular transmission solution is selected by the transmission requesting device. The multi-beam satellite system is scheduled to transmit a payload in accordance with the selected particular transmission solution. A system is provided that operates the method.

Abstract: A method is provided that enhances the throughput of data broadcasts in a multi-beam satellite communication system by taking advantage of target users whose normal environment or equipment provide a better channel performance than that of the nominal environment or equipment for which the system is tuned, which enables a larger coverage area per beam than the nominal design supports. A system is provided that operates the method. A preferred embodiment is described using the Iridium Mobile Satellite Service (MSS) system as a basis.
