Generally, RTK single base observation can produce a high precision if the rover within 20 kilometers coverage from used CORS base staion. RTK NTRIP observation needs internet connection to send correction data. Internet connection in RTK observation provide by five providers in Indonesia that is Telkomsel, Indosat, XL, Three, dan Axis. The longer range rover from base station in RTK observation reduce the value of precision. Precision in point positioning of RTK NTRIP observation affect by distance rover-base and also strengthness provider�s network. Therefore, was required the mapping of precision of RTK�s NTRIP CORS GMU1 observation from each telecommunication providers up to 20 km from CORS GMU1. The purpose of this project is to make comparison of the precision level from RTK�s NTRIP observations with CORS GMU1 as a base station using five providers. RTK NTRIP observation was done by using Leica Viva GS08 receiver. The observation sample is 64 points, the points distributed eight bearing direction in 20 kilometers radius from CORS GMU1. Every bearing direction consist of eight observations with 2,5 kilometers interval. Each observation point measured by five seconds recording interval in five minutes total measuring time, which use each five different providers (Telkomsel, Indosat, XL, Three, and Axis). Data analyst is by compare the precision value observation of RTK NTRIP from each providers. The result from the comparison indicate that Telkomsel, Indosat, and XL network�s provider is available in all observation locations, meanwhile Three and Axis provider only available in certain observation locations. The highest horizontal precision value in all RTK NTRIP single base CORS GMU1 observation locations produced by Axis with 0,003 m and the lowest horizontal precision produced by Telkomsel with 0,418 m. The average of highest horizontal precision produced by Three and Axis with 0,035 m. In available network condition, the observation of RTK NTRIP CORS GMU1 using Axis provider has result higher precision than the other providers. The horizontal precision inversely with the distance range from CORS GMU1 base station. The longer distance between rover from base station, the lower horizontal precision value result.
