The paper discusses the issue of relation between the accuracy and precision of GNSS/RTK measurements conducted at points with limited visibility of satellites. Field experiments were conducted from 2005 until 2010 on forest points characterised with different intensities of obstructions. The results of measurements obtained showed, which is characteristic for forest conditions, high precision but the accuracy of the results obtained ranged from under a centimetre to even a few metres. The analyses presented in this paper show that obtaining accurate coordinates from RTK positioning under forest conditions is possible but a method to eliminate gross errors must be developed.
