The fact that all parcels of land have not been registered in the territory of Indonesia has made the Government, in this case the Ministry of Agrarian Affairs and Spatial Planning, use RTK type GNSS measuring tools such as Comnav T300 and South G1 to accelerate land registration through land measurement and mapping. For this reason, it is necessary to know how the accuracy of the measurement results of the two types of GNSS tools uses the RTK-NTRIP method and how the tolerance of measurement results to the provisions of PMNA / KBPN Number 3 of 1997.

This study uses a comparative experiment method with a quantitative approach, which compares the measurement results of the RTK-NTRIP method NTRIP against static methods at variations in the distance of 1.5 km, 5 km, 10 km and 15 km ,. Researchers conducted an analysis using the Chi Square and Anova statistical tests on the value of lateral differences (dLi). The results of the study: first, the measurement results of the two tools using the RTK-NTRIP method showed good accuracy even though there were significant differences in the values of the coordinate differences as the base station distance to the rover increased. Secondly, the accuracy test meets the requirements of PMNA / KBPN Number 3 of 1997, so that measurements on the GNSS Comnav T300 and South G1 using the RTK-NTRIP method can still be used up to a radius of 15 km.
