Evenlode Lite is the latest offering in the Evenlode Video and Data downlink family. The system offers an entry level end-to-end video downlink solution for aircraft Integrators requiring a video downlink for ISR aircraft upgrades or capability uplifts. Evenlode Lite retains all of the reliability and performance expected from the Evenlode ISR video downlink family.

Evenlode Lite retains all of the reliability and performance expected from the Evenlode ISR video downlink family. An Evenlode lite, consists of an Air Data Terminal (ADT) used to downlink a single video, audio, GPS, KVL metadata*** and telemetry data from the air platform to the Ground Data Terminal (GDT).

Evenlode Lite is a series of equipment from the Evenlode Data Link range providing capability for a range of Information Exchange Requirements; equipment may be deployed for police, border guard and search and rescue applications. 

Evenlode Lite has a defined upgrade path; from Evenlode Lite to Evenlode I, II and Evenlode III as user requirements develop building on previously installed hardware. Operating on several fixed frequency bands, utilising Coded Orthogonal Frequency Division Multiplexing (COFDM) technology with enhanced modulation techniques. COFDM has been chosen for this Digital Video Broadcasting (DVB) system because of its broadcast quality capability and tolerance to multi-signal paths.

Evenlode Lite utilises the latest H.265 ECS video/audio & data encoder and decoder offering multiple video formats and resolutions across an ultra-low latency link securely with sub-cipher or full AES-256** encryption.
The ADT equipment is DO-160G certified and may be installed as a fixed stackable unit or as individual modules in the aircraft, employing a single 2dBi transmit antenna. Evenlode Lite Ground Data Equipment is delivered in a single softcase enclosure employing a single 7/8dBi* receive antenna. Declaration Design Performance and Interconnecting Diagrams along with user and installation manuals are also included in this solution.

Designed for the storage and loading of encryption keys into ECS COFDM equipment. The KFD uses three standard AA batteries and has low current draw even in full operational mode. The battery compartment has a coin release cover. The KFD can be used to either upload or zeroise the encryption key data contained within an ECS COFDM product. It is constructed of a robust aluminum housing and contains security enforcing features which reduce the likelihood of the stored data becoming compromised. The KFD is PIN protected.

It has been shock and vibration tested, is IP67 sealed which protects the device against dust and temporary immersion in water to a depth of 150 mm. The Encryption keys are generated by a Key Fill Interface Graphical User Interface (GUI) and transferred by USB to the KFD for storage and loading. The KFD is supplied in a Pelicase which also houses the connecting cables.
