The Impact of Troposphere Correction for Designation of the Ellipsoidal Height of Aircraft at Approach to Landing Procedure

The paper reports on research into the effect of the troposphere correction on the accuracy of the vertical component determination of an aircraft’s flight as it approaches landing at Deblin Airport. The article presents ellipsoidal height value of the aircraft when the troposphere correction is considered in navigational calculations and when it is not taken into account. Accuracy of the aircraft positioning in the vertical plane using the SPP method is determined. The study shows that application of the troposphere correction in navigational calculations increases the accuracy of the vertical component determination by 25%–32%. The article and the study may serve as a valuable source of information for pilots, flight instructors and aircraft crews during training in operation and implementation of GNSS in aviation.
