Analysis level of accuracy GNSS observation processing using u-blox as low-cost GPS and geodetic GPS (case study: M8T)

Abstract

The Global Positioning System (GPS) is a satellite navigation system and positioning that is owned and managed by the United States of America. This system is also designed to provide three-dimensional position and speed and information about time, continuously throughout the world without depending on time and weather, to many people simultaneously. The GPS module undergoes system expansion on low-cost devices by producing low-cost and energy-saving devices, including being able to provide L1 satellite data equivalent to geodetic GPS. This study shows whether low-cost U-Blox GPS can be equivalent to Hi-Target V60 geodetic GPS. The test was carried out by observing the four corners of the Geomatics Engineering volleyball field and PWK ITS using the RTK method. The results of GPS observations were carried out statistical tests to see if low-cost U-Blox GPS can be equivalent to GPS Geodetic Hi-Target V60.
