ABSTRACT:
An altitude dead reckoning system using a measured forward speed and a measured forward-looking acceleration in a dead reckoning (DR) altitude calculator to calculate an altitude change. The DR altitude calculator may also use a measured yaw angle rate to provide compensation to improve the accuracy of the altitude change calculation.
