GPS is nowadays the most important GNSS and the only one fully operational. Nowadays, this navigation system is becoming omnipresent in our society. Cars, vessels and airplanes include a GPS receiver to travel. The GPS receivers are also found on cellular phones and laptop computers. The IT GPS monitoring station is continuingly receiving data from GPS system. All this received data is acquired with the aim of being used to support the research and development of navigation algorithms. This data includes, among others, the orbital parameters (ephemerides), the GPS almanac and the satellite status. However, the monitoring station does not store permanently this data. The aim of this project is to implement a database application to store all these values. This database uses the MySQL technology. Firstly, a reader programs are create to read these parameters and send it to the database. Users can access to the database using a website. Using it, users can create and send queries to the database. The results of these queries are shown on the website or it can be downloaded on a file. Furthermore, the application supports the real-time upload of the database as well as the download of data. A backup system is implemented to protect the data. This system creates each week a file that contains all received data. The project involves the integration of several navigation, communication and computing equipment. The first part of this report includes a study of GPS to understand this navigation system and the parameters that are used. After this study, all the parts that compose this project are presented. These parts are: the data acquisition, the database and the website.
