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

FIELD: measuring equipment.

SUBSTANCE: method for determining a coefficient of reducing the a priori assessment of the accuracy of determining azimuth with gyrotheodolite relates to geodesy, can be used in a priori calculations of the accuracy of determining azimuth with a gyrotheodolite or gyro-compass (hereinafter gyrotheodolite), as well as when designing and validating the observation technique by any gyrotheodolite. Disclosed method comprises performing a calibration program of n starts (determination of n azimuth values a gyrotheodolite a_i control direction), calculation of deviations (a_i-a₀) for azimuths a_i, obtained by gyrotheidolite from each start, a₀ – reference value of azimuth, calculation of deviations (a_i-a_av) from average azimuth values for azimuths obtained by gyrotheodolite from each start, and calculating values of coefficients K_n for analysed gyrotheodolite at each of n starts by formula:

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