forest area, where the study has been performed, is coniferous. This brings an advantage with respect to transmission of the GPS signals to the receiver antenna. This is a significant feature for GPS surveying where conducted around the forest environment. Because, the characteristic features of the tree species may affect the accuracy of the point positioning with respect to sky visibility, cycle slip and multipath. For this experimental study, two test stations, which one (TP01) is near the border of forest area and the other (TP02) is in the forest area, have been established as seen in Figure 2. The detailed description of the location of points established may be seen in Figure 3a and 3b.
