Analysis on the Accuracy of a Network Real Time Kinematic GPS Using the Steel Tape and Triangulation

Abstract:

The purpose of this Study is to analyze the accuracy of a network RTK GPS, by performing taping, triangulation & Network RTK (Real Time Kinematic) GPS observation on certain measuring points and comparing all locational data based on the calculational & geometric solution method. The deviation in the measured length & coordinate between the steel tape and the Network RTK GPS was within 2cm while the deviation in the measured coordinate between the triangulation and the Network RTK GPS was within 3cm. With the fact that the performance of the taping or the triangulation is less sensitive to its surroundings taken into consideration, it could be concluded that an average locational accuracy of most Network RTK GPS processes in Korea was within 3cm.
