General Description

The Evenlode Ground Data System is a modular system that complements the Evenlode Series of Airborne Data Terminals. The GDS is based on a half width 19” rack system that provides ground based equipment from test transmitters and receivers through to long range bidirectional tracking antenna fixed base stations.
 
The Evenlode GDS provides a suite of antenna options ranging from covert omnidirectional antennas to tracking antennas that can achieve ranges in excess of 200 nautical miles.
Enterprise Control Systems Ltd (ECS) provides the complete ‘turnkey’ ground solution including: antennas, cabling, lightning protection, receivers, transmitters, power supplies, test equipment, installation and training.
 
Equipment that is available in the Evenlode Ground Data Terminal
system:
 
- Rack Transceiver
- Rack Dual Receiver or X-Versity Receiver
- Antenna Control Unit (MSA5, 6, 9 and Steerable)
- Mast Mounted Power Amplifier and Power Supply
- Rack ASI/IP Decoder (Dual and Single)
- Mains or Battery Power Supplies
- Range of antenna solutions from omnidirectional to high gain tracking dish antennas

Technical Data

The Evenlode Rack Transceiver comprises of a COFDM diversity IF receiver and a COFDM IF transmitter. The front panel incorporates a 5” LCD video monitor and a 128x64 Dot Matrix display for local control and BIT status of the Transceiver.
 
The Transceiver transmits and receives Real Time Video (RTV), audio and telemetry data. In addition the unit acts as an Ethernet Bridge to a suitable Evenlode Air Data terminal (Evenlode III).
 
The Rack Transceiver can be programmed to decrypt the incoming stream or decryption can be removed for secure onward transmission of data over IP networks. This Transceiver can be used as part of a fixed ground station or as part of a portable ‘fly away’ system.
The unit is ‘network voting’ compatible.
