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.

The article describes the possible disturbance of the Earth’s dynamic balance due to climate changes throughout the last 150 years and technogenic impact. An accident occurred on an oil platform in the Gulf of Mexico on April 20, 2010 is taken as an example of such impact. It is assumed that the accident may have accelerated the slowdown of the Gulf Stream and changed its path, which led to a change in temperature, salinity and density of significant ocean masses. Variations of ocean mass density in some areas could cause a shift of the Earth’s center of mass by 10–5 m and a deviation of its rotation axis by 2.9∙10–6 arcsec. It is shown that the process of disturbance of the Earth’s dynamic balance can be accompanied by an increase in the number of relatively weak earthquakes (in a range of magnitudes 4.2–4.8 by 41.5%) and the intensity of seismic noise (tremor), as shown by broadband seismic networks and satellite GPS navigation data.
