This research aims to identify the manner in which orographically factors influence the horizontal precision of GPS coordinates. The study area is a mountainous region in the Bran locality, mainly covered with spruce forests. Data was collected using the Stop&Go method with post-processing, using two GPS receivers (Trimble Pro XH and Pro XT). Data was stratified considering the following criteria: orography (valley, slope, crest) and aspect (S-N, E-V). Field data was post-processed and the resulting precisions were analysed using the Statistica software. The influencing factors were analysed individually, but also in different combinations. The best accuracy was obtained for points located on crests, followed by points on slopes (which had a good precision) and finally points in valleys (which had acceptable or low precision).
