Abstract. A variant of constructing a strapdown inertial vertical gyro with the use of correction for the indicated speed and barometric altitude is studied. Integration is performed on the basis of an extended Kalman filter for an aircraft of the airplane scheme. The pitch and roll angles are used as parameters of the local vertical direction. Mathematical modeling is carried out.
