A graphics workstation field artillery forward observer simulation trainer

Abstract

Today's forward observers need a low cost, realistic training system that fully prepares them for operations in any area of potential conflict. We present a graphics workstation method of training Field Artillery forward observers to call for and adjust indirect fire. Our system uses the dynamics and flexibility of computer graphics to simulate mobile observers and targets operating in a three dimensional environment. We produce three dimensional terrain from Defense Mapping Agency (DMA) Level 1 Digital Terrain Elevation data (DTED). The program depicts a functionally accurate, on screen Digital Message Device (DMD), the same device forward observers use to input missions. To allow field use in Field Artillery operations, we convert the DMA terrain files from geographic coordinates to the Military Grid Reference System (MGRS). We describe our simulator, the Forward Observer Simulation Trainer (FOST), listing its capabilities and features.
