I am trying to reconstruct the trajectory of an object with an strapped down IMU on board to do dead reckoning. A Kalman filter seems to be in order. But the Kalman filter seems to be oriented toward real time updates of position. However I have the luxury of not having to figure out the position of the object while it is moving. At the end of the path I will have all the data(gyros and accelerometers and maybe magnetometers) I can use to calculate the path. Is there something better than Kalman that can be used?
Right now I have a superficial understanding of the Kalman filter so forgive me if this question is a little dumb. I did not want to get involved with the Kalman filter if it is sub optimal.
