Establishment of Taiwan's standard operating procedure for network-based RTK in cadastral surveying

Taiwan completed construction of GNSS reference stations for the network-based RTK system in 2007. The legal mode of operation used in Taiwan requires that each point be repeatedly observed for at least two observation sets separated by 60 min. This study presents a simplified field operating procedure, which measures 10 epochs of fixed solutions during each observation set and reinitializes observations 10 times. In addition, the national and local network-based RTK system were used. The average horizontal positioning accuracies were 1-3. Finally, a workflow is presented for using the network-based RTK to measure the control points in cadastral surveys.
