Methods for Evaluating Dynamic Accuracy of Integrated DGPS/INS Algorithm Using Antenna Cluster with Network RTK and Post-processed Charier Phase DGPS

Abstract

In this paper, we propose the method to evaluate the dynamic accuracy for integrated GPS/INS algorithm in the marine environment. Most of previous works for evaluation of dynamics accuracy were suggested for test in land experiments. While, in land environment, the reference positions were mostly produced using a ground truth with the known position and the high resolution camera, the ground truth and the camera cannot applied in the marine environment. The evaluative methodto be proposed is to use antenna cluster including two precise positioning systems. One is Network RTK (NRTK) in Korea which is serviced by Korea National Institute. The other is the post-processed Carrier phase DGPS (CDGPS) with the localbase station. The sea trial is conducted in Korea to validate the proposed antenna cluster.
