Abstract
The analysis of the instrumentally observed variations in the error of determining coordinates by the GPS navigation satellite system, performed at the Mikhnevo Geophysical Observatory of Sadovsky Institute of Geosphere Dynamics of Russian Academy of Sciences, during periods of magnetic storms, is carried out. Using a sample of 50 events that occurred in the period 2016–2019, it is shown that magnetic storms (geomagnetic activity index Kр ≥ 5) cause a noticeable increase in the GPS positioning error. The data obtained suggests that positioning error can be used as an indicator of the disturbed state of the ionosphere and atmosphere during magnetic storms, as well as a parameter that characterizes the degree of disturbance of the environment and the conditions for the propagation of GPS signals.

Estimation of coordinates by code pseudo-ranges without using using phase counts.
In this work, we used the complex Morlet wavelet.
