Determination and Measurement of Horizontal Control Points 2nd Order

Since 2015 Politeknik Negeri Batam (Polibatam) Established Geomatics Engineering Program Study. As a Higher education vocational in Batam wich orientation to train student practical ability and skill especially in Geomatics Engineering Science need some infrastructure like campus building, Practical training instruments and Horizontal Control Point with high accuracy. Since the establishment of Polibatam, there has been no Horizontal Control Point making, so it is necessary to establish a Horizontal Control Point in Polibatam. High accuracy Horizontal Control Point from this research can support Land Surveying Practical, Global Navigation Satellite System (GNSS) Surveying Practical and Final Project/Thesis about that scope. Determination and measurement Horizontal Control Point in this research was performed by pulling Control Coordinate from Badan Informasi Geospasial Geodetic Control Net 1st order at Hang Nadim Batam Airport then the measurement using Relative Static Method. Results from this research are 7 Benchmark (BM) Point 2nd order in Polibatam has been Built. Determination of point Coordinates BM 1-4 and 6-7 second order has been measured with 2 hours observation, while the determination of point Coordinates BM 5 has been measured with 20 minutes observation. The biggest standard deviation is 0.007560 on the Z axis on BM 5 this happens because it is measured by observations of 20 minutes or in other words the observation is not long enough. The results from this Horizontal Control Point can support the practicum of the Land Surveying, the Global Navigation Satellite System Survey and the final project on the problem.
