Abstract:
A method of performing a navigation calculation on the basis of a hybrid inertial navigation system on board a vehicle, the method comprising the steps of: performing a hybrid first navigation calculation and an inertial second navigation calculation; calculating in real time a difference between the first navigation calculation and the second navigation calculation, and subjecting the difference to lowpass filtering having a convergence time longer than a period of the Kalman filter and shorter than the Schuler period; and using the filtered difference to correct the second navigation calculation.

Claim (Index 2):
A method of pointing an aiming device on board a vehicle provided with a hybrid inertial navigation system performing the method of  claim 1 , wherein the corrected second navigation calculation is used for pointing the aiming device.
