Abstract

This article presents the results of studies concerning the designation of accuracy in aircraft navigation positioning by means of the SPP and the SBAS code methods. The examination of the aircraft positioning accuracy was made in the aspect of the use of tropospheric correction in observation equations of the SPP and the SBAS positioning methods. The accuracy of the coordinates of the aircraft in the SPP and the SBAS solutions was referenced to the DGPS reference solution. The investigations were conducted on raw observation data and GPS navigation data in an air test in Dęblin. Based on the conducted calculations, it was proved that the lack of use of tropospheric correction in the SPP method causes an error in an aircraft position up to 18.5 m, and in the SBAS method up to 23.2 m. In addition, the statistical measure of RMS accuracy in the absence of applying the tropospheric correction in the SPP method results in an accuracy decrease to 8.6 m, and in the SBAS method to 12.2 m, accordingly.

Highlights

Along with the use of GPS satellite technology in aviation, there has been a rapid increase in the methods of aircraft precise positioning in the area of air navigation
The position of the aircraft will be determined based on the SPP code method in the GPS system, the SBAS method for EGNOS corrections, and the DGPS differential method
This paper demonstrates the results of research into the aircraft positioning accuracy by means of the SPP, SBAS and DGPS methods
