Rapid Bacteriological Water Test

Because of GPS outages, supplemental positioning capabilities are required tomaintain a robust position location for vehicles. Existing inertial systems aretoo expensive for use on all but the highest value military vehicles. Eventhough civilian vehicle navigation systems use map matching, military vehiclesare often not constrained to established roads making map matching not feasiblein many circumstances. This project will establish new methods of using lowcost sensors, such as MEMS gyros and accelerometers to provide vehicularpositioning and navigation capabilities at low cost for light military vehiclessuch as the HMMWV. The various classes of sensors in many cases havecomplementary strengths and weaknesses allowing valuable synergy to be gainedthrough integration. Mathematical models for the sensors will be developed andincorporated into a computer simulation. The sensors will provide input to avehicle dead reckoning navigation algorithm. The simulation will be used topredict accuracy and performance under varying conditions and to develop aKalman Filter algorithm that will blend data from motion and directional sensorswith position data from GPS. A prototype navigation systems will be designed built,tested and delivered.
