Analisis Pengolahan Data GPS Menggunakan Perangkat Lunak Rtklib

Abstract

GPS (Global Positioning System) is a navigation and positioning system using satellites. One of accuration factors using GPS is data processing strategy. By following the GPS demands in human life, GPS observation data can be processed using a variety of the softwares. RTKLIB is one of the softwares using for GPS observations data processing.This research observation uses points observations using GPS Dual Frequency by static method so that it is known a characteristics and the result of software processing. This result is then analyzed using RTKLIB and Topcon Tools software. The result of those softwares then compares to the result of processing Bernesse scientific software.The results of this research show that there is a difference between the deviation standard value of RTKLIB software and the deviation standard value of Topcon Tools software, with the mean value of σN and σE amounting -0.0011 and -0.0026 m respectively. RTKLIB has a better deviation standard accuracy and closer to the value of secondary data, that is the result of Bernesse. According to statistical test with 95% confidence interval, it is concluded that there is no significant differences between the result of RTKLIB and Topcon Tools software
