Hilton Communications recently completed a satellite uplink and downlink system for Germany’s largest television news broadcaster. The project includes six antennas and associated control infrastructure that will be used to communicate with the network’s affiliates around the world.
hilton antenna control unit (ACU) is designed to control a 3-axis motorized antenna. The antenna control unit and associated motor control electronics are housed in an IP65 rated weatherproof outdoor housing with a hinged front access port secured by dual key screws. Each control unit can be operated from a PC running a graphic user interface compatible with standard her web browsers. The control GUI displays all the information needed to set and maintain azimuth, elevation and polarization. This includes current and target positions and a database of accessible satellites.
“After successful acceptance, we created a solution that fully integrates into your news production workflow‘ said Hiltron’s Managing Director. Antonio Monteverde.Easy and efficient operation was an essential requirement. The antennas are installed in city center rooftop earth stations and operated via a remote link from the network’s master control room. Hiltron software allows you to monitor your system via a single browser-based display screen showing all relevant performance parameters, reliability lights and alerts. Most importantly, the antenna panel de-icer automatically activates when the roof temperature creates a freezing hazard.“
“All six new antennas are used to capture incoming signals.‘ said the Hiltron project manager. Guy Van Bambeke.Five of the reflectors are from General Dynamics, one 3 meters in diameter and four 3.7 meters in diameter. Sixth, he was a 2.7-meter laminus dish, which he equipped in orbit to simultaneously capture feeds from three positions, in this case 7 degrees east, 13 degrees east, and 19.2 degrees east.Each antenna is on a fixed mount. We have also refreshed the three existing antennas that act as both uplinks and downlinks. That part of the project included providing and integrating the Hiltron ACU Antenna Control Unit used to control the azimuth and elevation of the antenna. Each consists of a stand-alone unit contained in a weatherproof outdoor housing and operated remotely via an IP data stream from a standard PC. Once a satellite is selected, exact access parameters can be determined with the push of a single button. Finally, we integrated 13 Swedish microwave low noise block downconverters. These are high performance units that ensure the received data is fully compliant with broadcast specifications.“
