KESALAHAN POSISI (DISPLACEMENT) DATA HASIL PENGUKURAN ALAT GPS GARMIN 78s TERHADAP DATA PENGUKURAN ALAT TOTAL STATION PADA TITIK - ITIK TOWER SUTT 150 KV AMUNTAI - TAMIANG LAYANG

The government has committed to build a power plant of 35,000 Megawatts (MW) in stages by providing infrastructure the form transmission, substations and generating sources. One transmissions that can function distribute from generator source load centers is 150 kV High Voltage Air Line (SUTT) transmission. purpose this study was analyze Displacement generated Garmin 78s GPS Tool against Total Station Measurement Data. SUTT Amuntai - Tamiang Layang consists 120 tower points along transmission line using determine position data. Position errors search for occur, so analysis method uses descriptive statistics find out real error on average two coordinate GPS. tool used project points. Based results study, 427.57 meters calibration 0.23 (23%) weighted 3.56 meters.Keywords: displacement; total station; 78s.
