Combat Simulation Analysis Lab

Client: United Defense Limited Partnership (UDLP)


The completed CSAL built by CGSD for United Defense L.P.

An armored vehicle simulator was delivered to United Defense LP (UDLP), manufacturers of the Bradley fighting vehicle. CGSD integrated components including a Silicon Graphics Onyx/RealityEngine2 computer image generator, Gemini real time software and sound system, MaK Technologies network interface software, and Loral ADS ModSAF (computer simulated forces) and network gateway. The gateway will permit the simulator to participate in Distributed Interactive Simulation (DIS) exercises with other simulators in industry and government nationwide.

The system includes CGSD-designed multiple custom consoles, crewstation controls and touchscreen displays implemented on networked personal computers, and a video system providing ten out-the-window viewpoints. System costs were substantially reduced by using off-the-shelf hardware and software whenever possible. CGSD wrote all of the custom software required to integrate the system.

The configuration includes a three channel stealth console and crew stations for the commander, driver, and gunner. The stealth and each crew station includes a PC-compatible computer interfacing the controls to the Onyx via a local Ethernet, separate from the DIS ethernet. The system includes simulated controls and multichannel sound systems.

Gunner's station (near) and Commander's station use some actual Bradley controls.

Note the three narrow views, mimicking the vision blocks of an armored vehicle. The three views are generated one-above-another in one video channel; the identical video is then displayed on three monitors which are stepped on supports to align the views.

The "Stealth" station is for an oberver to view the simulation.

The Stealth console also contains the Modular Semi-Automated Forces (MODSAF) control computer. MODSAF is software that generates simulated friendly and opposing forces in the simulation. The operator supplies the overall tactical strategy for the forces, which the software then carries out in detail.

The system was delivered to UDLP's Santa Clara, CA, in early 1995, seven months after contract award. Since then it has been the focal point of many successful demonstrations by UDLP. The system meets a strong need to be able to first demonstrate by simulation proposed changes in weapons systems.

United Defense will use the simulator for armored vehicle research and engineering development. The multi-processing Onyx computer, initially configured with four processors, will permit accurate simulation of vehicle mechanics in real time, including engine and suspension models.
