High Accuracy Geodetic Control Point Measurement Using GPS Geodetic With Static Methods

Abstract

Abstract. The quality of the coordinates of the points in a generally horizontal control network will be influenced by many factors, such as the system equipment used for measuring / observation, the network geometry, measurement strategies / observation, as well as data processing strategy implemented. Using development of the GPS satellite system, since 1989, the network provision of horizontal control points in Indonesia generally relies on the GPS satellite observations. One way of measuring geodetic control points with high accuracy is using geodetic GPS. Measurement of geodetic control points required as a control in the execution of the work and as a correction coordinate measurement of the position of a measurement object with a high degree of accuracy (± 1 cm). How many measurement methods that can be done. This research conducted measurement using static method. Static surveys are used to determine the coordinates of the control points are relatively distant from each other as well as order accuracy requires relatively higher. The measurement results obtained coordinate data for point 1 is 6 ° 57 '31.92207 "LS; 109 ° 38 '32.25194 "BT; high (ellipsoid) 34 320 m and point 2 is 6 ° 57 '33.59086 "LS; 109 ° 38 '37.87710 "BT; high (ellipsoid) 36 235 m.

Accuracy of marine gravimetric measurements in terms of geodetic coordinates of land reference benchmark

“…The locations of points in global geodetic coordinates were obtained in post-processing using Leica Geo Office v8.4 and proprietary scripts. The calculation process also used data obtained from observations made at points of known locations (GBAS) [36].…”

Koreksi Titik Reference Dengan Metode Statik Pada Pengukuran Mikro-Topografi Pada Perkebunan Kelapa Sawit

“…Jaring kontrol geodesi (JKG) yang mempunyai ketiga nilai (horisontal, vertical, dan gaya berat) hanya berjumlah 317 titik (BIG, 2019), sehingga masih sangat terbatas terutama pada areal-areal remote seperti perkebunan kelapa sawit. Penentuan titik reference dengan metode static merupakan cara yang efisien dan relatif mudah dilakukan (Correa-Muños & Cerón-Calderón, 2018;Julianto et al, 2018;Santoso, 2014). Pada pengukuran elevasi terdapat beberapa jenis elevasi yaitu elevasi ellipsoid, geoid, dan ortometrik (Gambar 1).…”

Uji Presisi dari Nonholonomic Mobile Robot pada Rancang Bangun Sistem Navigasi

“…Perkembangan tingkat akurasi GPS sudah mulai meningkat, bahkan dengan geodetic GPS akurasi yang didapatka sampai 1cm [4]. Namun dengan akurasi tersebut hanya berupa data, sehingga perlu sensor tambahan.…”
