Analysis of Navigation Satellite System based on the Ground Control Points (GCP) at Universiti Kebangsaan Malaysia

Abstract

This study presents data measurements to identify the best navigation system in terms of its positioning accuracy. The data global positioning system measurements is done using a GPS South device measured in four locations which are one random point and three different places based on the Ground Control Points (GCP) in Universiti Kebangsaan Malaysia (UKM). The coordinates of these locations are already in the Cassini Soldner Selangor Coordinate system. The results and analysis of signal noise to ratio (SNR) and path loss is discussed to indicate the performance of positioning accuracy among the four existing Global Navigation Satellite System (GNSS). The Global Positioning System (GPS) signal is dominant in location A and China’s BeiDou Navigation Satellite System (BDS) signal is also dominant for other three locations. In general, the BDS signal had the highest number of signals detected in this experiment which is total of 57 signals in four locations. By evaluating the positioning accuracy can improve the environmental studies such as tracking, monitoring, surveying, and mapping of climate change.
