The experimental results of the RTK GPS measurement using 3G mobile network and internet

Abstract

This paper presents the experimental results of the RTK GPS established by the authors with different distance measurements. With a 5km baseline, the RMS of RTK solution is 2.8 cm and ratio of fix solution is approximately 90%. With these results, this RTK GPS system meets the requirements of large scale topographic and cadastral mapping, hydrographics surveying, especially the work of layout works and high accuracy RTK for ITS (Intelligent Transportation Systems). The equipment used in this RTK system available on the market, the system easy to replace, compact, low cost, capable of measuring continuous RTK in one day and especially allows using of many rover receiver simultaneously .
