Abstract. The article is devoted to the issues of assessing the evenness of airfield pavements. The authors present a developed methodology for determining long-wave irregularities in airfield pavements using the universal road curvimeter «Rovnost» (Evenness), which ensures an increase in the accuracy of measurement work. Measuring the evenness of runways by geometric leveling with a survey step of 0,5 meters or using a three-meter straightedge is a labor-intensive process. The use of the «Rovnost» curvimeter for determining pavement evenness allows for the automation of the measurement and survey data processing process. However, when surveying long-wave irregularities from 50 to 100 meters, shortcomings related to the influence of gyroscope axis drift on the accuracy of determining the irregularity amplitude have been identified. To improve the accuracy of measuring the amplitudes of long-wave irregularities, the authors propose a methodology that includes an additional measurement of the elevation mark by the «Rovnost» curvimeter using a global navigation satellite system receiver synchronized with the gyroscopic system. The measurement error of satellite receivers, unlike a fiber-optic gyroscope, does not depend on time, which allows, during synchronous coordinate measurements, to determine the gyroscope axis drift and compensate for (minimize) its influence on accuracy, thereby determining the differences in elevation marks, the deflection arrow, and corrections due to gyroscope axis drift. The use of satellite receivers in the proposed technical solution increases the cost of work, but this cost is significantly lower than the cost of instruments for determining the «evenness» indicator with laser gyroscopes or creating a reference elevation geodetic network using geometric leveling.
