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 method and system for delayed random access is provided. In order to attempt to capture a channel, each VSAT randomly chooses when to load and where to transmit. Each of the VSAT schedules the transmission of data when the date that needs to be sent, utilizes more than a present percentage of the channel and/or when a predetermined delay has elapsed. When multiple sources transmit data through a single VSAT, the system may withhold transmission until it aggregates enough data to efficiently utilize the channel. Alternatively, when there is a time out, the VSAT transmits the data regardless of the utilization of the channel. Blocking of a channel by a VSAT can be prevented so that the channel can be used by another VSAT in a more efficient manner.

摘要： In a satellite communication system comprising at least a hub and a plurality of terminals, at least one terminal may include a cache for storing data objects. The cache may be based on a detachable memory device that may be inserted to or removed from the terminal at any given time, including after the terminal is deployed. Aspects are directed to preventing a prefetching of objects already stored in a cache of a remote terminal. In some embodiments, an efficient multicasting of content to terminals over an adaptive link may occur in a manner which may benefit terminals comprising a cache while not affecting or minimally affecting the performance of terminals that may not include a cache.
