The integration of Global Positioning System (GPS) and real-time kinematics (RTK) has been widely used in many applications, such as mobile mapping and autonomous vehicle control. Such applications require high-accuracy position information. However, continuous and reliable high-accuracy positioning is still challenging for GPS integration in urban environments because of the limited satellite visibility, increasing multi-path, and frequent signal blockages. Low cost GPS module has been widely used in various applications in the last few years. Low cost GPS module offers various features of global positioning system, including Standard Positioning Service (SPS), static post processed positioning and Real Time Kinematic (RTK) GPS. This project highlights the application of external low cost and high accuracy RTK GPS module for precise geo-tagging using smartphone. The Application Created by Ionic 4 and build by Android Studio. Using this Application Accurate Latitude and Longitude can be observed.
