    摘要: A VSAT telecommunications system including a satellite (14), first (10) and second (36) VSAT terminals, and a hub (12) communicating via the satellite (14) with first (10) and second (36) VSAT terminals, the transmissions from the hub (32) are generally continuous, while transmissions from the VSAT terminals (20 and 26) are generally in bursts, and the at least one first VSAT terminal (10) has the capability of receiving transmissions from the hub (32) but lacks the capability of receiving transmissions from another VSAT terminal (26), and the at least one second VSAT terminal (36) has the capability of receiving transmissions from the hub (32) and also has the capability of receiving transmissions from another VSAT terminal (20).

    摘要: Efficient utilization of a shared pool of time-frequency slot resources in a return channel among a plurality of remote terminals in a satellite communication system. Within the shared pool of time-frequency slot resources for data, allowing access through circuit-switched TDM allocations, reservation allocations, or random access. Within the shared pool of time-frequency resources for control, allowing duplicate control burst transmissions in random access. Other improvements in the control channel include self-allocation by the remote terminals or hub-allocation to the remote terminals.

    摘要: A system and method for automatically positioning/directing satellite antennas towards a satellite with which it is to communicate. The system and method may use characteristics of symmetry of mutually exclusive orthogonal axes. By using the symmetry of the antenna main beams, the ideal direction of the antenna can be attained and, at the same time, maximum cross-polarization may be achieved. The cross polarization may be required in order not to interfere with the orthogonal polarization. The system and method may position the Antenna on three mutually exclusive orthogonal planes, including the azimuth plane, the elevation plane, and the polarization plane. The system and method may include an indoor unit, which may include a satellite receiver, a telemetric transmission, and supply of voltage to a control system and which may control a drive motor and/or an electronic search device; and an outdoor unit, which may include a supervisory unit, a motor, and a control unit. The outdoor unit is preferably configured to conduct a search in the three orthogonal planes which may facilitate positionining the Antenna with a high degree of accuracy.

    摘要: A wideband transceiver for a gateway is presented. The wideband transceiver may interface with the gateway's processors over an interface that carries data encapsulated in baseband frames. The wideband transceiver may comprise a modulator and a high power amplifier and may improve a transmitted signal quality and may utilize a wideband for wireless communications, for example, for a satellite communication system.

    摘要: A method for satellite communication over non-geosynchronous orbit (NGSO) satellites, using a terminal having a non-tracking antenna, is presented. The terminal may communicate with an NGSO satellite each time the NGSO satellite passes through the terminal's antenna beam (communication opportunity). Though the communication opportunities are short and may reoccur at relatively long intervals (e.g., minutes to tens of minutes), these communication opportunities may be sufficient for transmitting the volumes of information generated by Internet of Things (IoT) applications during the intervals between communication opportunities.

    摘要: Examples disclosed herein describe an antenna architecture (e.g., a planar electronically steered antenna architecture) that enables operation at low elevation angles, down to zero degrees from the satellite. The proposed '3SA' architecture may improve power consumption and array footprints. The proposed '3SA' architecture can support aero terminal implementation on aircraft, enabling the use of GEO, MEO and LEO satellites even in regions having low elevation angles. The architecture may include a horizontal antenna array and vertical antenna array as well as a controller for switching between the antenna arrays.
