MARIN, L. E. et al. Comparison of elevation heights using a Differential Global Positioning System (DGPS) and a Total Station. Geofís. Intl [online]. 2008, vol.47, n.1, pp. 81-83. ISSN 0016-7169.

Differences in elevation for a set of 12 different points were determined using a Total Station and a DGPS three receivers with occupation times of 90 minutes per station). A comparison between both sets of elevation values shows differences of two to 36 millimeters for a maximum baseline of 2,420 meters. These results show that differential GPS surveys may be used to determine differences in elevation using the differential GPS technique.
