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.
Highlights
Geodetic network can be defined as a form of geometry that consists of three or more points geodetic measurements, which measurement consists of a horizontal distance measurement, the azimuth angle, etc. [2]
Measurement of geodetic control points with high accuracy are conducted in SMK 1 Kedungwuni Pekalongan
The location was choosen because it has curriculum of geomatics competence and as a form of institutional cooperation between research institutions with schools as partner in helping to provide learning media and training in the use of geodetic GPS equipment
Summary
The method of determining the position of a point by means of terrestrial is done based on measurements and observations of the earth. While the method of extra-terrestrial, positioning is performed by measurement or observation to the object / celestial bodies, whether natural (such as the moon, stars and squar) and man-made such as satellites. In the development of extra-terrestrial survey, the use of GPS surveys are often used to determine the geodetic control points, both horizontal control points and vertical control points, where to take measurements control framework is not independent of geodetic network. Geodetic network can be defined as a form of geometry that consists of three or more points geodetic measurements, which measurement consists of a horizontal distance measurement, the azimuth angle, etc. Geodetic network can be defined as a form of geometry that consists of three or more points geodetic measurements, which measurement consists of a horizontal distance measurement, the azimuth angle, etc. [2]
