Communication is extremely important in the technological world for fast and accurate exchange of information in real time. In the military in particular, this is important for the ability to make quick decisions and to allow constant monitoring of the situation by the commander who manages the communication. A communication module that would allow a commander to monitor his unit in real time via a mobile device (which we all own today) would make a significant contribution to modernizing communication in the military system. The communication module would not only provide information on the current location of the unit (in the form of geographical coordinates), but would also measure the speed of its movement. This communication module could be constantly upgraded to give the commander all the information he needs in a particular command role, and that is what the military equipment system strives for, modernization and constant progress. The aim of this final work is to create exactly this communication module, which would allow information to be exchanged between a mobile phone and a system that runs a map of space with geodata (via QGIS). Communication needs to be established regardless of whether the server and the client are on the same network. Realizing server-client communication, where the server would be a mobile device and the client a computer system on which the QGIS application is running, would enable the option of tracking unit movements. This communication module could, if its software is correct and functional, start to be used in the civil and military world for monitoring. It offers numerous possibilities that lead to technological progress.
