6 g6 (see Figure 1).
IV.3 ROVINS Center of Measurements
The ROVINS center of measurement P is the intersection of the three ROVINS reference
axis X1, X2 and X3 defined in Inertial Products - Principle & Conventions (Ref.: MU-
INS&AHRS-AN-003) . It lies inside ROVINS, and its exact position is reported on Figure 2.
The ROVINS center of measurements P is the reference point for the determination of
ROVINS and external sensor lever arms (Refer to the document Inertial Product -
