Evaluative Devices for Dynamic Accuracy of GPS Receiver in Coastal Navigation Using Carrier Phase DGPS

Abstract

In this paper, the evaluative device for dynamics accuracy is suggested for experiments at coastal navigation by using carrier phase DGPS. The device consists of three antenna mounts. Two outside antennas are used for getting reference positions. One of them is for Network Real Time Kinematic (NRTK) positioning provided by Korea National Geographic Information Institute and another is for the post-processed CDGPS(Carrier phase Differential Global Positioning System) with thelocal base station. The centered antenna is used for test systems such as standard GNSS or DGNSS. Simply averaging the positions from two outside positioning systems can give the reference position for the test antenna. The suggested device for evaluation of dynamic accuracy is assessed by sea trial at the coastal area.
