TLDR
In this paper, a servo control device (A) is provided for the data from the inertial unit of the carrier (CNp) of a missile and a Kalman filter is provided, mounted in parallel on the said servo controller device, intended to identify the harmonisation errors between the two inertial units.Abstract:
System permitting, for example, initialisation of the inertial unit (CNm) of a missile from the inertial unit (CNp) of the carrier of this missile. According to the invention, a servo control device (A) is provided for the data from the inertial unit of the carrier (CNp) in the inertial unit (CNm) of the missile and a Kalman filter (K) is provided, mounted in parallel on the said servo control device (A) and intended to identify the harmonisation errors between the two inertial units.read more

Arrangement for determining the time-variant position and the errors of a repeater navigation system relatively to a master system
TL;DR: In this paper, the time-variant position of a repeater navigation system relative to a master navigation system (10) is determined by using a Kalman filter (18) for which the measured angular velocities and the difference ( DELTA a) of measured accelerations are connected.

Arrangement for initializing and/or recalibrating a repeating inertial navigator.
TL;DR: In this paper, a model which simulates the mutual relationship between a main and a repeating inertial navigator is proposed. But the model is limited to the case of a single main and an RIN.
