Paired navigation altimeter and method for dead reckoning height measurement

摘要

A deadweight navigation altimeter comprising: a speedometer configured to determine a forward speed, an accelerometer configured to measure forward acceleration, a yaw rate sensor configured to measure a yaw angular velocity, a yaw compensator configured to compensate the measured acceleration according to the yaw angular velocity to determine a compensated acceleration; DR height calculator configured to calculate a height change based on the measured velocity and the compensated acceleration.
