The article proposes a solution to the problem of operative data collection for correcting electronic chart data and ensuring safe navigation. A subsystem for obtaining cartographic data with the help of the Remotely Piloted Aircraft Systems (RPAS) has been developed. On the basis of data received from RPAs, it is possible to create a draw layer for an electronic chart with new coordinates of objects. Creation of such layers will make it possible to objectively evaluate the situation taking into account possible parameter changes for selected key objects. In case of continuous parameter change, for example, the change of shoreline coordinates, this layer is sent to a hydrographic service for introducing changes to the official electronic chart. When using the RPAS, the system will allow to track changes in real time, which at present is possible only with the help of space satellites. © Transport Means - Proceedings of the International Conference.
