摘要：
In one embodiment, a system and method of dead reckoning navigation for a vehicle uses a set of accelerometers. Sensed accelerometers from the set are converted into a vehicle body frame of reference set of accelerations. The resulting converted accelerations are then used to determine a dead-reckoning longitudinal acceleration for the vehicle. By integrating the longitudinal acceleration along a heading for the vehicle, a dead-reckoning-determined location for the vehicle is provided.
