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

印尼地区移动卫星信道特征的实证研究

在本研究中，我们测量和分析了GPS信号强度，利用软件进行数据检索、处理和测试GPS接收器，这些接收器具有在固定条件下(静态)确定用户位置的能力，并在地图上显示视觉显示。在印度尼西亚的三个地点，在一些航路点和2(2)种条件下观察到的实验位置。选择这些地点是为了代表印度尼西亚三个地点的LOS和NLOS的情况。选定的地点是坦格朗市、班贾巴鲁市和帕洛波市。本实验只关注用户(用户GPS接收机)的固定状态(静态)。对12个PRN输入的NMEA数据进行排序并绘制成图形。利用XGPS显示各PRN卫星信噪比的质量。根据实测结果表明，在Palopo市开放空间条件下，12个PRN处于主动状态，且每个PRN都具有良好的信号强度质量，获得的效果最好。在Palopo市开放空间条件下，从prn17接收到的信噪比值为49.12 dBHz，效果最佳
