Abstract
In this research we measured and analyzed GPS signal strength by utilizing software for data retrieval, processing and testing of GPS receivers with ability to determine user position on fixed conditions (static) with a visual display on the MAP. The location of experiment observed at three locations in Indonesian on some waypoints and 2 (two) conditions. The locations were selected to represent the condition of LOS and NLOS in three locations in Indonesia. The selected location are Tangerang City, Banjarbaru City and Palopo City. This experiment focused only with fix condition (static) of the user (the user GPS receiver). The inputted NMEA data from 12 PRN sorted and plotted in graphical form. The quality of each PRN satellite signal to noise ratio displayed using XGPS. Based on the result of field research shown that the best result obtained in Palopo city with open space condition which the 12 PRN is in active condition and each of them has a good quality of the signal strength. As for best result of signal to noise ratio value received from PRN 17 in open space condition in Palopo city which is 49.12 dBHz
