When using modem high-precision sensors used, in particular, on AHBS, the issue of the reliability of the readings and the detection of random errors arises. The accuracy of the readings of hydrometeorological factors measuring instruments today does not satisfy the increased requirements for navigation accuracy. Therefore, a new approach to determining errors, as well as a method for determining reliability, is required. The proposed method is based on the collection and analysis of data obtained from gauges correctly located according to the criteria described in the article. The accumulated large amount of measurement data is approximated and processed by the moving average method to obtain a predictive model. The results of the predictions, in turn, are processed by the Allan variation method. This approach provides the measurement of the noise component of the measurements. The experimental results revealed a measurement error below the declared accuracy of the gauge, which indicates the reliability of the readings.
