Quality control of GNSS RTK positioning using mobile devices for its application on location apps

The main purpose of this project is to improve the positioning behaviour of the Android smartphones, using them as station of Global Navigation Satellite System (GNSS). Focusing on the main errors that occurs by different factors and affect on the phone location and applying solutions, to achieve the understanding of the behaviour of the devices under different situations. For the Rinex data collection the app Geo++ Rinex Logger has been the main support, different Android smartphones has been checked during the process and, furthermore, an u-blox device is involved in this project. The collected data, is processed with RTKLib software, which allow to perform a post-processing and a real time study. Obviously, this project has many applications in an industrialized world, but it is focused on the usage of a better location service of smartphones on apps, to ensure that a non-desired failure cause an undesired performance, ending with unsatisfied clients.
