Product Description

The Evenlode Ground Data Terminal provides decoding and monitoring of all signals contained within an ECS COFDM Evenlode downlink. The downlink may consist of up to two high definition video channels, two audio channels, GPS position of the Air Data Terminal, telemetry data and, bidirectional Internet Protocol (IP) Data. COFDM downlink parameter matching is automatic. The Ground Data Terminal may be used to transmit data in IP and serial formats to the Air Data Terminal. This uplink data could be used for remote control of sensors, selecting sensors or be used to control and monitor downlink parameters by remotely accessing the Air Data Terminal. Local and remote control are provided by Graphical User Interfaces (GUI).

GPS information from the aircraft transmitter is fed to the ACU to select the link-facing sector within each MSA. This provides high gain performance with an excellent range. Using an omnidirectional receive antenna in diversity improves downlink resilience: the highest quality COFDM signal is chosen from the two antenna inputs on a carrier-by-carrier basis and in real time.

The Evenlode Ground Data Terminal has been designed to be portable, lightweight and rugged whilst maintaining full functionality of an Evenlode 19’’ rack static system.
