Contribution of BeiDou Positioning System for Accuracy Improvement: A Perspective from Bandung, Indonesia

Currently, BeiDou Navigation Satellite System (BDS) has been operating in Asia-Pacific especially in Indonesia Region. BDS is expected to enhance the accuracy of positioning, include for static survey. Aim of this research is to estimate the positioning accuracy improvement for static survey in Bandung Indonesia. The methodology applied in this research are the GNSS data collecting using COMNAV T300 GNSS receivers from 13 GPS stations using network design, data processing by using GPS only and combined used of GPS and BeiDou data, and analyzing of accuracy improvement. The result indicates that the combination of BDS data (B1 and B2) with GPS (L1 and L2), compared with GPS (L1 and L2) only, provides a better accuracy by 31.3% in easting, 49.9% in northing and 13.6% in height components, and in precision by 20.1% in easting, 30.7% in northing and 32.7% in height. Finally, it can be expected to improve positioning accuracy by using BeiDou system for static survey in Bandung region.
