Abstract
A system and method for dead reckoning for marine positioning applications is provided. After INS mechanization, an exponential moving average (EMA) is calculated that is used to generate an update for a Kalman filter. The use of the EMA allows the system to limit position error in a linear fashion while being self-contained.
