METHOD FOR DETERMINING A COEFFICIENT OF REDUCING A PRIORI ESTIMATION OF ACCURACY OF DETERMINING AZIMUTH WITH A GYROTHEODOLITE SET Russian patent published in 2019 - IPC G01C1/02

Abstract RU 2696808 C1

FIELD: instrument engineering.

SUBSTANCE: invention relates to the field of navigational instrument-making, in particular to methods for increasing the accuracy of georotheodolite complexes, and can be used, for example, in systems for calibrating gyroscopic observations. Method includes: performing program of calibration (reference) of N gyrotheodolites (determining N by gyrotheodolites of azimuth value a₁ control direction); calculation of deviation (a₁-a₀) from a₀ – reference azimuth value for azimuths a₁, obtained by each gyrotheidolite; calculation of deviation (a₁-a_av) from average azimuth values for azimuths obtained by each gyrotheidolite; calculating coefficient value K_N for the gyrotheideolite set under study by formula

EFFECT: high reliability of a priori estimation of accuracy of determining azimuth with a gyrotheodolite set.
