Abstract: A method and a system are provided for use in a satellite communications network in which broadcasting services are provided to a mobile terminal. The method comprises: duplicating bits comprised in communications which the satellite is about to broadcast, thereby forming a first stream of bits and a second stream of bits; conveying the first stream of bits in an encoded form along a satellite channel whereas the second stream of bits is conveyed in an encoded form along a terrestrial channel; and combining bits conveyed along the satellite channel with bits conveyed along the terrestrial channel in order to obtain a combined stream of bits.

Abstract: A novel digital baseband beam forming system is disclosed including a plurality of digital baseband beam forming channels configured and operable for connecting via channel ports to a plurality of antenna channels associated with respective antenna elements for at least one of transmitting and receiving through the plurality of antenna elements one or more waveform signals encoding data streams. The digital baseband beam forming channels are configured and operable to apply at least one of phase and time delays of selective magnitudes to baseband signals associated with data streams encoding the waveform signals transmitted and/or received by the plurality of antenna elements, thereby beamforming said waveform signals to produce, by said waveforms, one or more data encoded beams associated with respective directions of propagation and encoding said data streams respectively. The digital baseband beam forming system may be implemented in chip (e.g.

Abstract: Antenna and satellite communications assemblies and associated satellite tracking systems that may include a low profile two-way antenna arrangement, tracking systems, and applications thereof. Applications for the system include military, civilian, and domestic emergency response applications. The antenna arrangements may be configured to form a spatial multi-element array able to track a satellite in an elevation plane by electronically dynamically targeting the antenna arrangement and/or mechanically dynamically rotating the antenna arrangements about transverse axes giving rise to generation of respective elevation angles and dynamically changing the respective distances between the axes whilst maintaining a predefined relationship between said distances and the respective elevation angles. The system provides autonomous dynamic tracking of satellite signals and can be used for satellite communications on moving vehicles in a variety of frequency bands for military and civilian applications.

Abstract: A low profile low cost mobile in-motion antenna system for satellite TV reception using DVB with different either BPSK or CDMA like modulation schemes is described. In some embodiments, a low resolution version of a video transmission may be used as a backup for a higher resolution version of the video transmission.

Abstract: Method, system and apparatus for providing dedicated service, using transponders arranged on the geostationary orbit, including satellite television and other data to moving vehicles, equipped with small (less then 30 cm in diameter), low profile antennas, and using signal spreading technique in order to increase the downlink signal strength and to reduce the interference from adjacent satellites ensuring in that way enough margin for the reception by the small size low-profile antennas.

Abstract: A method and apparatus for providing satellite television and other data services to moving vehicles. In the method of the invention, substantially the full power of the transponder of a satellite, normally associated with bit rates of more than 30-40 Mbps, is reduced to a lower bit rate, for example, 1-2 Mbps, associated with between one and six video channels. As such, more power is provided per channel, allowing easier reception by small aperture antennas used on or in the moving vehicles.
