Enterprise Control Systems Ltd Launch new Diversity Soft Case Receiver System

Posted 2015-09-16

Enterprise Control Systems Ltd (ECS) have recently unveiled the new Coded Orthogonal Frequency Division Multiplexing (COFDM) Diversity Soft Case Receiver System (High Definition) which consists of all the components of the new ECS ground station system and will be showcased at the forthcoming DSEI and Helitech 2015 exhibitions. The system is housed in a 5U 19’’ rack fly away case for temporary and mobile use. 



External to the Soft Case Unit are three antennas and a Low Noise Block (LNB) downconverter. The antennas include an active switched Multiple Sector Antenna (MSA), an omnidirec­tional antenna and a Global Positioning System (GPS) antenna. All other components of the system are installed within the soft case: a Half Rack COFDM Video Link Diversity Receiver, an Half Rack Antenna Control Unit (ACU) and, a fold-out HD 17’’ rack monitor.

The Diversity Soft Case Receiver System (HD) provides de­coding and monitoring of all signals contained within an ECS COFDM HD downlink. All information within the ECS COFDM HD downlink is decoded within the Diversity Receiver. The downlink may consist of up to two video channels with associ­ated audio. GPS information is also multiplexed onto the MPEG Transport Stream of the aircraft transmitter. The Soft Case Receiver outputs the HD signal in DVI and HD-SDI format. If the transmitted signal is a Standard Definition (SD) video signal this will be output in composite (CVBS) format. GPS information from the aircraft transmitter is fed to the ACU to select the link-facing sector within the MSA. This provides high gain reception with an excellent range. Using an omnidi­rectional antenna in diversity improves link resilience: the highest quality COFDM signal is chosen from the two antenna inputs on a carrier-by carrier basis and in real time. The Diversity Soft Case Receiver System (HD) has been de­signed to be portable, lightweight and rugged whilst maintaining full functionality of static ECS receivers.

Please note:  the system described includes a High Definition Soft Case Receiver, a GPS active antenna, an external downconverter with an omnidirectional antenna and, a Multi-Sector Antenna.  Other arrangements of external components are available according to customer range and portability requirements.
