SES: BAE Systems - Brunei Offshore Patrol Vessel Programme

Under subcontract to BAE Systems Marine, as part of the Brunei OPV Programme, SES developed several distinct systems for supporting the installation and setting to work of the Ship's Data Distribution System, T1007 Radar and AWS9 Radar Driver, for the Royal Brunei Navy.

Navigation Radar Simulator Driver

The driver is capable of presenting up to 50 targets detected by the navigation radar to the Command and Control System of a military naval vessel. Under subcontract to BAE SYSTEMS Marine, SES developed a software-based real-time simulation driver for a Navigation Radar. The driver runs as a service under Windows NT and was written in Visual C++.

The driver provides data filtering, bandwidth limiting, and plot reporting operations on data that is produced by a Scenario Generator, and then delivers the processed data, with millisecond accuracy to a Radar Video Generator.

The driver is used in the Land-Based Integration Facility (LBIF) for the offshore patrol vessels (OPV) that have been delivered to the Royal Brunei Navy.

Ships Data Distribution System Simulator

For BAE Systems Marine, SES have developed a stimulator capable of simulating 18 different navigation sensors and concurrently stimulating a Command and Control System and other data users with sub-millisecond accuracy.

As part of the Brunei Frigates programme, SES developed a stimulation system capable of driving the main Ship's Data Distribution System for the vessel, with multiple inputs simulating multiple real world systems. The stimulation is carried out in real-time with a single equipment simulating GPS, Echo Sounder, EM Speed Log and the Ships Gyroscope. The stimulator has been developed in Visual C++, as a service running under Windows NT and makes use of numerous hardware interface cards to provide the special interfaces that are used to communicate with the ships data distribution system.

The SDDS Stimulator receives ownship positional data representing GPS, Echo Sounder, EM Speed Log and Gyro information over an Ethernet connection which it processes, performing necessary interpolation/extrapolation, then outputs the reformatted data over various interfaces which consist of:

• 7 RS422 serial links
• 14 Synchro links
• 3 Volt-free contacts

The stimulator works as part of a coordinated realtime simulation, "deceiving" the ship's command and control system into believeing that it is at sea, providing realistic stimulation of all required interfaces.

Weapon Radar Emulator Driver

The Weapon Radar Driver is part of the Brunei OPV LBIF programme. Its function is to process platform data broadcast over the Simulation Highway by the Scenario Generator, and transmit Plot Manoeuvre Messages and Azimuth Change Pulse Messages to the Weapon Radar Emulator over an Ethernet link with millisecond accuracy.

The system provides data filtering, extrapolation and Azimuth Change Pulse (ACP) allocation operations on data that is produced by a Scenario Generator, and then delivers the processed data , with millisecond accuracy to a Weapons System Radar Emulator.

The driver is used in the Land-Based Integration Facility (LBIF) for the Off-shore patrol vessels that are to be delivered to the Royal Brunei Navy.

The driver works as part of a coordinated real-time simulation, "deceiveing" the Command and Control System into believing that it is at sea and simulates radar contacts with synthetic targets, thus allowing the systems developers to investigate the extremes of performance of the real system. The radar simulator is able to maintain output information on up to 80 tracks, representing any combinations of ships, static targets, aircraft and missiles.
