Comparison of accuracy of GPS techniques

Accuracies of relative positioning techniques namely rapid static, pseudo-kinematic, kinematic, and real-time kinematic are investigated to determine their performances against static survey technique that yields the most precise results. Measurements are taken at seven National Geodetic Survey points along Road 714 in Florida using three sets of triple frequency Global Navigation Satellite System receivers. The data are processed using the software provided by the manufacturer. It turns out that pseudo-kinematic technique produces the closets results to static survey results.

► Pseudo-kinematic technique produces the closets results to static survey results.
► It turns out that RTK technique produces the worst results.
► In case, a radio is not available, rapid static and kinematic techniques yield good performance.
► Satellite configuration is more appropriate for horizontal coordinate determination.
