In this study, we have organized a revival project for Time Synchronization and used a Raspberry PI & GPS Module to capture The GPS Signal and parsed the Signal for building NTP Server. After building NTP Server, we are going to make a GPS handset by adding touch screens to our Raspberry Pis and we're going to use this handset for locating the trees at the Kandilli Observatory and Earthquake Research Institute Campus. At the end, collected the data will be used at the free and open source web GIS software for our project.
