26 Aug 1998TL;DR: In this article, a converter for the direct down-conversion of direct broadcast satellite signals such as those used for digital television is presented, in one embodiment by a single integrated circuit comprising a variable gain amplifier (VGA), frequency synthesizer, quadrature generator and a plurality of mixers.
Abstract: A converter for the direct down-conversion of direct broadcast satellite signals such as those used for digital television. The direct broadcast satellite signal received from the satellite dish is amplified and then downshifted within the Low Noise Block (LNB), a subsystem contained with the satellite dish assembly, to a predetermined frequency band, typically in the L-band in the range 950 MHz to 2150 MHz. The signal is then sent via a coaxial cable to the set-top box unit located indoors, and there directly converted from the received frequency to baseband, in one embodiment by a single integrated circuit comprising a variable gain amplifier (VGA), frequency synthesizer, a quadrature generator and a plurality of mixers.

TL;DR: In this article, a SCANS system with a satellite uplink communication module which transmits data to an earth orbiting satellite is presented. But the system is limited to a small satellite dish to receive data from the satellite.
Abstract: A system and method which delivers data at very high data transmission speeds to many locations simultaneously. A SCANS system is supplied with a satellite uplink communication module which transmits data to an earth orbiting satellite. The satellite then retransmits the data over a wide geographical area. Each receiving location is equipped with a small satellite dish to receive data from the satellite. Advantageously, the satellite dish is connected to a work station in the switching office which then processes the received data and delivers all information in a form that is ready for use by the modules' switching office. Errors during data transmission are noted for further processing. After the data is broadcast from the beginning to the end, the SCANS system pauses for a brief interval during which time each receiving station performs error detection, error correction, and other recovery procedures on the data it just received. The SCANS system, using satellite transmission, then broadcasts data once again from the beginning to the end. Receiving stations then selectively acquire data that was missing or in error after the first transmission.

TL;DR: In this article, the satellite dish antenna is moved in a first rectangular spiral search pattern to obtain a rough-tune position corresponding to the detection of a signal peak for a selected audio subcarrier frequency in a selected channel of a target satellite.
Abstract: A receiver connected to the satellite dish antenna receives signals from an electronic compass for generating a magnetic direction signal. The approximate latitude and longitude values of the parked vehicle are displayed and the user of the system manually selects the latitude and longitude coordinates corresponding to the parked vehicle location. The receiver determines an initial search position for the satellite dish antenna based upon the magnetic reading and the entered latitude and longitude values. The satellite dish antenna is moved from an unstowed position to an initial search position. The satellite dish antenna is then moved in a first rectangular spiral search pattern to obtain a rough-tune position corresponding to the detection of a signal peak for a selected audio subcarrier frequency in a selected channel of a target satellite. The frequency selected is not present in corresponding selected channels of satellites near the target satellite. A fine-tune search is then performed and the method calculates all the azimuth and elevation positions of all remaining satellites.

TL;DR: An antenna assembly includes a reflector dish and a unit attached at a distal end of an arm to receive satellite signals reflected from the reflector dishes as discussed by the authors, which includes at least one lownoise block converter (LNB) to receive the satellite signals and a wireless communication transceiver that operates to transmit and receive video and data information within a surrounding range.
