Patent number: 11662207Abstract: Inertial measurement apparatus arranged to be carried by a carrier vehicle include a chassis, a turntable mounted on the chassis, a first inertial measurement unit mounted on the turntable and connected to an electronic control unit connected to a motor for controlling turning of the turntable, and a second inertial measurement unit secured to the chassis. The control unit turns the turntable through one revolution with periodic alternating motion from a fixed initial angular position of the turntable. The control unit calculates the acceleration of the carrier vehicle from measuring the first inertial measurement unit while the turntable is stationary and from measuring the second inertial measurement unit while the turntable is moving. The control unit reconstitutes an inertial reference frame for each inertial measurement unit and compares the two inertial reference frames to determine a difference and takes account of this difference when calculating the acceleration.Type: GrantFiled: November 20, 2019Date of Patent: May 30, 2023Assignee: SAFRAN ELECTRONICS & DEFENSEInventors: Christian Lignon, Philippe Elie, Sylvain Faure
