DETERMINATION DE PARAMETRES DE NAVIGATION INERTIELLE D'UN PORTEUR

The invention relates to a method for determining navigation parameters for a carrier of an inertial navigation system, wherein computer processing means (3) of said inertial navigation system (1):- determine at least two sets of parameters (Vi) each representative of the navigation of said carrier from navigation measurements and at least two sets of information, said at least two sets of information each being updated at different calibration moments using reference information (REF) communicated to the carrier, - determining the navigation parameters (PN) of the carrier by adding said at least two sets of parameters (Vi) with weight coefficients (αi) that vary periodically, each weight coefficient (αi) being zero at the calibration moment of the set of information using which the set of parameters (Vi) to which said weight coefficient (αi) applies is determined.
