The COTS based design and architecture of the SES C3DU product range offers microprocessor based units that enable the operator to monitor and control connected systems. The design of the C3DU makes custom features easy to implement with minimal bespoke adjustment and modification of standard SES products. However when the requirements can only be achieved with a bespoke solution SES offers wide experience in design and manufacturing areas as demonstrated through diverse project examples, including:
BAE SYSTEMS contracted SES to supply a pilot's interface for the Harrier IWP2 and GR9 programmes. The interface was to provide display of instrumentation status and parameter information, selectable by a keypad to give the pilot control of the functions of a new instrumentation system. Two display units were provided based upon C3DU products, a HDD (Head Down Display) and the Remote Display Unit (RDU).
The RDU solution was a C3DU-M implemented as a Night Vision Goggle (NVG) compatible, sunlight readable alphanumeric display based upon a 12 character DIS 323 LED module. The display brightness is continuously variable to allow it to be easily read under all lighting conditions. A compact enclosure was developed to allow mounting in a head-up location and to meet the interface connector requirements. Specific functions were incorporated into the design to provide Pilot alerts of monitored instrumentation failures and enable their acknowledgement.
The HDD is a customisation of the generic control display unit designated C3DU-G, developed from an existing SES Ltd. solution and benefiting from the pedigree and proven performance of that product. The C3DU-G was tailored for the HIPI project with special-to-type software and some hardware modifications to meet specific space and positional constraints imposed by an existing cockpit design. The unit is compatible with lighting conditions of an aircraft cockpit and includes a high brightness Electro Luminescent, sunlight readable display and is NVG compatible.
The C3DU-T is the man-machine interface for a Raytheon Successor Identification, Friend or Foe (IFF) system and provides the control and display functions necessary for an IFF Interrogator. COTS modules and sub-assemblies have been tailored to meet the physical and environmental requirements without compromising the unit's overall reliability.
The display is an LED alpha numeric module with discrete back-lit annunciators and is daylight readable and NVG compatible. Rotary switch controls and toggle switches provide operator controls. The processing core is a Microcontroller, complete with re-programmable external Flash ROM and on-board CAN interface. The functionality of the design is provided by software written in the ANSI C.
A single circular military connector is mounted on the rear panel for 28 V dc power and I/O connections. The case is a two part Aluminium Alloy (L99) casting. The front casting accommodates the Illuminated Front Panel, the Display Module, switches and an interconnecting circuit board. The rear casting accommodates the main circuit boards, power supplies, I/O connector, and feedthrough filtering.
SES provides a family of control and display units to support the Successor IFF programme including the C3DU-T and a Versatile Console System (VCS) configuration for Naval application.
The Cockpit Control Unit (CCU) provides control and status display for a Synthetic Aperture Radar (SAR). SAR is used to produce ground images from a moving platform similar to a photograph but unlike optical photography it can be used at night and through cloud.
The CCU is COTS based and a derivative of the SES C3DU-T. It was chosen by Thales Defence Systems because of the ability to tailor the COTS based product quickly and cost effectively to meet specific requirements where an "off the shelf" solution could not be found.
