There is a certain error in GPS positioning, but the time is synchronized and there will be no error.

GPS error of about 5 meters to 10 meters; GPS error**. In GPS satellite positioning measurements, the main errors** that affect the accuracy of observation measurements can generally be divided into three categories:Errors related to GPS satellites:

Satellite orbit error, satellite time table error. The reasons are; The ionosphere is refracted in the ionosphere between 50 and 100 km above the earth, and gas molecules are strongly ionized by various rays of the sun and other celestial bodies, forming a large number of free electrons and positive ions.

When a GPS signal passes through the ionosphere, like other electromagnetic waves, the path of the signal is bent and the propagation velocity changes, which skews the measured distance, an effect known as ionospheric refraction. There are three ways to attenuate the effect of ionospheric refraction: Using dual-frequency observations, a combination of observations at different frequencies can be used to correct the ionospheric extension.

Not very accurate.
