Abstract
In the first part of the article, the author proposed a modified method for confirming the ADS-B data, which estimates and compares the aircraft flight altitude: barometric altitude (received from a barometric pressure altimeter) and geometric altitude (received from a GNSS receiver). In the presented work, application of the modified technique for confirming the ADS-B geometric altitude data is simulated. When simulating, real data were used which were received from the ADS-B ground station located at the Mezen aerodrome. Real values of pressure and temperature were used. The methodology takes into account the values of quality indicators of ADS-B data. For one flight on local airlines, an excess of the permissible interval was shown (GNSS data, according to the methodology, are not confirmed). The result obtained is consistent with the geometric vertical accuracy parameter GVA. To verify the modified method of the temperature determination according to geometric and barometric altitude, the obtained temperature data are compared with the values of the ECMWF forecasting model. The average RMSE value for 11 flights was 1.58 ºС. For climbing aircraft the maximum RMSE value was 1.93 ºС, for landing aircraft, maximum RMSE = 2.7°C.
