The increase in the complexity of facilities entails the requirements increasing for the accuracy of geodetic measurements and the need to revise some existing techniques for accounting of factors’ variety that affect the measurements results of urban development. Such factors include the Moon influence on the magnitude and direction of gravity. In order to determine the need for adjusting the methods of accounting for the effects of the moon on the geodetic measurements results, an assessment was made of their maximum influence on the value of the earth’s gravity force and the deviation of plumb lines. The results of a computational experiment for estimating the extreme values of the variation in the plumb lines’ deviations (up to 1 “), the oscillations of the measured exceedances (up to 0.5 mm per 100 m) and variations in the gravity (up to 5.44 × 10-5 μg / s2) are sufficient grounds for correcting existing methods of precision leveling and gravimetric measurements.
