A Fundamental Study on the Characteristics of Rover Tracking using RTK-GPS

Abstract

RTK-GPS is one of the GPS positioning methods which enables real-time and high accurate positioning and is applied in surveying, machine control and so on. But the characteristics of RTK-GPS were mainly inspected on the observation with fixed antenna, and not with roving antenna. The authors have inspected the accuracy and initialization time of RTK positioning with roving antenna comparing with fixed antenna, and showed that the accuracy and initialization time did not differ with roving antenna and with fixed antenna. Also it was shown that the accuracy of north-southward is less than that of east-westward both with fixed antenna and roving antenna due to the geometrical allocation of satellites.
