Abstract
A strapped-down intertial system for a vehicle including computational means and a sensor package. The sensor package includes a first part (1) fixedly mounted on the vehicle, and a second part (5) which is rotatable about a first axis (Z). On the second part (5) are fixedly mounted gyroscopic means (13, 15) responsive to rotation about two axes, one of which is the first axis (Z), and accelerometer means (9, 11) responsive to acceleration along two axes, one of which is not the same as either of the two axes of the gyroscopic means (13, 15). The computational means is arranged to calculate the heading of the vehicle from the outputs of the gyroscopic means and accelerometer means taken with the first part (1) stationary, and the second part (5) successively in at least three different angular positions about the first axis (Z).
