Abstract : A gyro platform assembly for determining a drift rate of a sensing axis of a first gyro, the sensing axis being fixedly aligned to a carrousel axis. The first gyro is on a plane of a first platform. The first platform is connected to a vehicle along the carrousel axis. The first platform has the plane and an opening. A second platform is connected to the first platform within the opening. The second gyro is on a surface of the second platform. The second platform is carrouselable around a carrousel axis that is perpendicular to the carrousel axis of the first platform. The second gyro has a sensing axis that is adjustibly aligned with the sensing axis of the first gyro. When the vehicle rotates, each sensing axis experiences the same rotation rate. Each sensing axis produces a signal that is the result of the rotation rate of the vehicle, and a sensing axis drift rate. The second platform is carrouseled 180 degrees and the sensing axis of its gyro produces another signal. The drift rate of the sensing axis of the first gyro is determined from the three produced signals.
