General Description

Evenlode is a series of equipment providing capability for a range of Information Exchange Requirements; equipment may be deployed for air, ground and maritime applications. Evenlode is offered at three levels of complexity with a defined upgrade path. Upgrading from Evenlode I to Evenlode II to Evenlode III uses the previously installed hardware. Following initial deployment of technology, further capability may be added should the Concept of Operations be developed or changed. Equipment is offered as:
Evenlode I Video Transmitter/Receiver. An Evenlode I air transmitter and Evenlode I ground receiver may be used to downlink dual High Definition video, audio, GPS data and telemetry data from the air platform to the ground.
Evenlode II Video Transceiver. Evenlode II air equipment may be used to extend the range of a downlink via a relay system. An Evenlode II air transceiver and Evenlode II ground transceiver provides optional two-way video, audio, GPS and serial telemetry data capability.
Evenlode III Data Terminal. Evenlode III has the data exchange capability of Evenlode II. In addition, air and ground equipment may be deployed to extend the full range of Internet Protocol (IP) services to the air platform; these include internet in the air, remote sensor control form the ground, remote access to databases, augmented reality and shared white-boarding applications. The link between a pair of Evenlode III terminals behaves, in networking terms, as an Ethernet cable with a maximum data rate defined by the radio link parameters.
Air equipment is provided with omnidirectional antennas for point-to-multipoint video exchange. Ground equipment can be offered with a range of omnidirectional and position-steered antenna systems. The complexity of the antenna is dependent upon range and deployment requirements. Static ground equipment may be deployed across a wide area and networked to provide extended coverage.
ECS supplies an extensive range of ground receiving systems and transceivers capable of integrating with Evenlode. These include fixed, vehicle-borne, briefcase and handheld receivers and transceivers. ECS is able to provide omnidirectional, diversity, sector tracking, multi-input diversity and high-gain GPS tracking ground station options.
