Penentuan Posisi Stasiun Gnss Cors Undip Pada Tahun 2013 Dan 2014 Menggunakan Software Gamit

Station CORS GNSS (Global Navigation Satellite System) is a station that can measure the current position of a station point continuously for 24 hours. This station is a technology that developed and used by the department of defense and transportation, USA. GNSS CORS station of UNDIP began operating in December 2012, on the Geodesy major, Faculty of Engineering, Diponegoro University. This installation is based on the requirements of satellite-based navigation. This study focuses on determining the speed of GNSS CORS station UNDIP position in the year 2013 until 2014. The station CORS positioning needs to be done to estimate the movement of the point defining the coordinates of each year, continuously and periodically. The data used in this study include GPS observations in the year 2013 until 2014. This research project consists of udp1, udp2, udp3, and udp4 total using 14 observations stations, the stations is cnmr, coco, cusv, darw, dgar, Guam, iisc, karr, kunm, ntus, pbr2, pimo, sey1, and udip. Processing is done by using a scientific software, GAMIT.This study resulted the value of the position in 2013 and 2014 on udp1 observation strategy that has value -0.01217 m/year ± 2.24 mm for the X component, 0.02201 m/year ± 7.05 mm for the Y component, -0.01550 m/year ± 1.59 mm for the Z component. The value that resulted by the observation strategy udp 2 is -0.01133 m/year ± 2.00 mm for the X component, 0.02469 m/year ± 5.86 mm for component Y, -0.00005 m/year ± 1.37 mm for the Z component. The value that resulted by the observation strategy udp3 is -0.01188 m/year ± 2.27 mm for the X component, 0.02419 m/year ± 7.04 mm for the Y component, -0.01773 m/year ± 1.59 mm for the component Z. The value that resulted by the observation strategy udp4 is -0.01180 m/year ± 2.09 mm for the X component, 0.02487 m/year ± 5.91 mm for the Y component, -0.00004 m/year ± 1.39 mm for the component Z
