FIELD: aviation.
SUBSTANCE: invention relates to aviation equipment and can be used in air traffic management system under conditions of reduced vertical separation intervals. Way to increase the reliability of monitoring systematic errors in measuring the barometric elevation on airplanes is to allocate the area of space from the aircraft for monitoring. Data on horizontal coordinates, geometric and barometric elevations, as well as data on the vector of ground speed, heading and air speed is broadcast, the transmitted information is received by a terrestrial radio station. Entire volume of data obtained in the selected area of space is divided into observation sessions, each of which is defined in space and time. For terrestrial data processing, the difference between the geometric and barometric elevations and the averaged value of the wind speed are determined for each aircraft using a computational complex. If an increased wind speed is detected as a sign of the atmospheric front entering the observation zone, the data of the corresponding session is excluded from further consideration. Further, statistical processing of the obtained data is carried out and the error in measuring the barometric elevation on the aircraft is determined. For each aircraft, sessions with its participation are selected and, according to the results of statistical processing, a systematic component of the measurement error of the barometric elevation is allocated, which is compared with a given threshold. Aircrafts, for which the specified error threshold is exceeded, are recognized as aircrafts that failed to pass the verification.
EFFECT: increase in the reliability of the results of monitoring systematic errors in the measurement of the barometric elevation by eliminating unreliable measurements due to the influence of the atmospheric front from statistical processing.
