Abstract: A method and system for providing near real-time IP streaming services to a plurality of mobile terminals, each installed on a corresponding vehicle and each comprising a delay buffer. Interruptions due to artificial or natural obstacles are such to determine missing data in the delay buffer. The method and system address the management by the service control center of the transmission of the buffers refilling data to the mobile terminals with the aim of reducing the allocation of resources and service operational costs.

Abstract: Dual reflector offset mechanical pointing low profile telecommunication antenna, to be used above all on vehicles, even high-speed ones. Its reduced physical dimensions facilitate its use, with respect to the known solutions, as it allows its connecting to the receiving system, such as a satellite, though installed on a train or on an aircraft. The invention lies within the technical field of telecommunications and the applicative field of stationary, movable antennas of reduced dimensions, and accordingly within that of telecommunications in general. The original dual reflector antenna is obtained from a second-order polynomial that configurates it in the Cartesian space XYZ.

Abstract: Combined electronic/mechanical scanning antenna for fixed installations such as ground-based self-propelled vehicles, automobiles, trucks, etc., ships, satellites, etc., to connect fixed or moving stations. It may be used for radar applications. Compared to the current state-of-the-art, it combines mechanical and electronic scanning devices in a single system. Technical field of electronic systems and radar telecommunications included. Field of application: production of telecommunications systems.

Abstract: A transceiver or transponder particularly for synthetic aperture radar, or SAR, systems, operating in a frequency band having a central frequency, the transponder comprising a receiver (1) and a transmitter (2) both thermally stable and made by microstrip technology, the receiver (1) and the transmitter (2) being adapted to receive and to transmit, respectively, an electromagnetic wave provided with at least one linear polarisation, the receiver (1) being connected to the transmitter (2) by amplifier means comprising an amplifier unit (5) for each linear polarisation of the wave received by the receiver (1), each amplifier unit (5) including at least two amplifier stages (7, 9, 11) cascade arranged along a single microstrip and interconnected to one another and to an input and to an output of the corresponding amplifier unit (5) by means of coupling or matching stages (6, 8, 10, 12), the output signal of each amplifier unit (5) having substantially the same frequency as the input signal thereto, the amplifier
