INTEGRATED INERTIAL-SATELLITE SYSTEMS OF ORIENTATION AND NAVIGATION Russian patent published in 2017 - IPC G01S19/47 

FIELD: physics.

SUBSTANCE: system is proposed comprising an antenna module of the receiving equipment of a satellite navigation system, comprising, for example, two receiving antennas spaced at a distance less than the wavelength of the carrier frequency, is fixed rigidly in the axes of the measuring unit of the inertial module in the plane of the object deck; the measuring unit of the inertial module together with the antenna module of the receiving equipment of the satellite navigation system is mounted on a rotating base equipped with a drive to provide modulation rotation relative to the body of the non-carded inertial measurement module about an axis orthogonal to the deck; the drive is provided with an angle sensor measuring the rotation anglevalues of the measuring unit with the antenna module with respect to the body of the non-carded inertial measurement module tied to the axes of the object.

EFFECT: increasing the accuracy of generating object orientation parameters while reducing the length of the antenna base to the level of the carrier frequency wavelength of the satellite signal, expanding the possibilities for calibrating zero accelerometer and gyroscope offsets on the mobile object.
