METHOD OF FORMING BARINERTIAL HEIGHT AND VERTICAL SPEED Russian patent published in 2020 - IPC G01C23/00 

FIELD: aviation.

SUBSTANCE: invention relates to measurement information systems and systems of combat aircraft. Proposed method of forming barinertial height and vertical speed consists in using vertical channel signal of inertial navigation system implemented in accordance with discrete Kalman filtering and identification procedure, method includes parallel integration of a signal measured by a vertical accelerometer and comparison of integration results with provision of rough formation of vertical velocity, and calculation is performed in inertial-Doppler correction mode. At that at formation of measurement signals and observation matrix kinematic relations of communication of errors of measurement of angles of evolution of object and errors of calculation of the main three of navigation parameters are used with small angles of mismatch of real and reference trihedrons of gyroplatforms of inertial navigation system (INS).

EFFECT: development of high-precision, suitable for wide industrial application of method for formation of barinertial height and vertical speed, synthesized based on optimal integration of bar altimeter made from air signal system and vertical channel of INS operating in its inertial-Doppler estimation and correction mode.
