  /**
   * Robustly estimates gyroscope cross couplings and scaling factors
   * along with G-dependent cross biases introduced on the gyroscope by the
   * specific forces sensed by the accelerometer using a PROSAC algorithm to discard
   * outliers.
   * This estimator assumes that biases are known.
   * <p>
   * To use this calibrator at least 6 measurements at different known frames must
   * be provided. In other words, accelerometer and gyroscope (i.e. body kinematics)
   * samples must be obtained at 6 different positions, orientations and velocities
   * (although typically velocities are always zero).
   * <p>
   * Measured gyroscope angular rates is assumed to follow the model shown below:
   * <pre>
   *     Ωmeas = bg + (I + Mg) * Ωtrue + Gg * ftrue + w
   * </pre>
   * Where:
   * - Ωmeas is the measured gyroscope angular rates. This is a 3x1 vector.
   * - bg is the gyroscope bias. Ideally, on a perfect gyroscope, this should be a
   * 3x1 zero vector.
   * - I is the 3x3 identity matrix.
   * - Mg is the 3x3 matrix containing cross-couplings and scaling factors. Ideally, on
   * a perfect gyroscope, this should be a 3x3 zero matrix.
   * - Ωtrue is ground-truth gyroscope angular rates.
   * - Gg is the G-dependent cross biases introduced by the specific forces sensed
   * by the accelerometer. Ideally, on a perfect gyroscope, this should be a 3x3
   * zero matrix.
   * - ftrue is ground-truth specific force. This is a 3x1 vector.
   * - w is measurement noise. This is a 3x1 vector.
