METHOD TO DETECT ORIENTATION OF PILOT HELMET AND DEVICE FOR HELMET SYSTEM OF TARGET DESIGNATION AND INDICATION Russian patent published in 2014 - IPC F41G3/22 

FIELD: measurement equipment.

SUBSTANCE: inventions relate to the field of measurement equipment, in particular, to systems of orientation and navigation. Sensitive converters are installed on a pilot helmet and in an AC cabin, connected to a calculator. The sensitive converter on the pilot helmet is made in the form of a radio interface and a helmet MPIB rigidly fixed on the zone of its sighting device, comprising nanomechanical gyroscopes (NMG) with autoemission. The sensitive converter in the AC cabin is made in the form of a calculator arranged in the indicator block of its windscreen, representing a module comprising a microcontroller and a radio interface transceiver. For initial linkage of the system of coordinates of the micromechanical platform-free inertial block to the system of coordinates of the aircraft (AC), they determine angles of rotation of coordinate axes of the MPIB system of coordinates to their matching with axes of the AC system of coordinates, and values of these angles are recorded in the memory of the computer. Average values of angular speeds are calculated, as well as absolute and relative spatial position of the helmet. Data exchange between sensitive converters is carried out by means of a radio signal.

EFFECT: increased accuracy of measurement, flight safety and convenience of piloting.
