As Baltic Sea is known for frequent shipping accidents like groundings, collisions and other types of accidents, the challenge was to prevent and minimise the accidents´ frequency. The causes of the accidents are partly related to human-driven failures and partly to technical inefficiencies. The maritime users expressed their needs in more optimal solutions to ensure more accurate positioning, navigation and time information.
While navigating, the ships need to ensure safety when the established Global Navigation Satellite Systems (GNSS) fail due to interference or jamming. A technical system that would allow for safe ship navigation under these conditions was lacking. Signal disturbances would cause wrong positioning or temporary outages of the GNSS positioning equipment.
The project R-Mode Baltic intended to tackle the challenges related to disturbances and develop a new independent of GNSS system that would allow a safe and more accurate positioning.

The R-Mode Baltic project as a forerunner
The R-Mode Baltic project became a forerunner for the implementation of the maritime terrestrial navigation system. The system is called R(anging)-Mode and enables to increase the safety of maritime transport. The project brought together research institutions, national maritime service providers and industry partners. The partners further developed the R-Mode technology and verified R-Mode as a suitable approach for coastal navigation.
Furthermore, the project started the standardisation process of R-Mode for maritime infrastructure. The first guideline for R-Mode on very high frequencies was finished. Further guidelines, recommendations and performance standards are under development. Additionally, the project introduced ship and shore site R-Mode prototypes.
The first worldwide large-scale R-Mode testbed introduced
The project set up the first worldwide large-scale R-Mode testbed. With its transnational character, the testbed brings Germany, Poland, Sweden, and Denmark together in their efforts to protect the environment and prosperity of the Baltic Sea region by reducing the threat of shipping accidents. The testbed provided a platform for a variety of tests and further development of the navigational system. Furthermore, it can be used for training, demonstration and gathering experience from system operation.
Supporting material developed
Besides the R-Mode system applied in the southern Baltic, the project generated the material which includes R-Mode signal design for two communication systems, the approaches for digital signal processing and methods for positioning with the help of R-Mode signals. The Interreg project R-Mode Baltic used EUR 3.1 million from the European Union to improve maritime safety, prevent the increasing number of shipping accidents, to test the alternative technical solutions, and make available the documented work for broader use.
