Positioning with medium frequency R-Mode

Kurzfassung

R-Mode is a terrestrial navigation system under development for the maritime domain that provides backup in case of an GNSS outage. This paper describes the first test results for real-time positioning on board a ship using medium frequency R-Mode signals. The estimation and positioning algorithms used are described in detail and it is shown how they are integrated into the R-Mode receiver developed by the German Aerospace Center. Moreover, different scenarios are described that were tested during a measurement campaign in the Baltic Sea, where we were able to demonstrate for the first time that the R-Mode Baltic testbed for the medium frequencies is functional.
