Study Of Military Amphibious Vechicle Positioning And Directioning System

After comparing all kinds of vehicle navigation system , the thesis use dead reckoning as the way of military amphibious vechicle position and direction . The thesis analyse the error and the feasibility of the system . Because the precision of position and direction is related with the precision of the heading and the distance , the thesis discuss the method of obtaining the distance using milemeter, water milemeten engine's rotate speed and accelerometer , and the method of obtaining the heading using the combination of the gyrocompass and the digital compass . Then the thesis introduce the details of the system realization , include the hardware and the software . The thesis also discusses the computer simulative testing program . Kalman filter is used to deal with the accelerometer's output . Finally , the thesis gives the experimental data of the system and the conclusion of the research .
