Verification of the precision of GSM and GPS signals available on mobile devices

The research work presents the study of the quality of telecommunications and satellite signals. For this purpose, a proprietary application for mobile devices has been designed, which allowed the collection data. The tests were performed on several models of cell phones and for different operators. The test checked the impact of such things as weather conditions, device architecture, device age, type of terrain. Based on the results, heat maps were created to visualize the research.
