Maritime AI-NAV

Maritime transport currently faces significant challenges, including increases in transport volumes and more stringent environmental requirements. Shortage of skilled workers at sea is also a possible threat for the future. Artificial Intelligence / Machine Learning Sensor Fusion for Autonomous Vessel Navigation (Maritime AI-NAV) will see how these challenges are to be answered by technology.

INCUBATE - Indoor navigations from cubesat technology

LEO small satellites are cost-effective which will make it possible to provide PNT services to new user groups that cannot be reached by traditional GNSS services, while creating new types of commercial opportunities. Technology related to small satellites enable creating new business models when development is done together with companies. INCUBATE -project aims to enhance these types of activities. We intend to investigate how PNT (positioning, navigation, and timing) operations based on LEO satellites can be used in indoor environment. In addition, and partly together with companies, we will explore the commercial potential and prospective revenue streams generated by the solution. The satellite signal and its reception has to be optimized for us to be able to determine a sufficient performance of satellite signal for accurate PNT indoor service. In addition, we are developing the utilization of existing small satellites and designing a new satellite, FinnPNTSat, for positioning. We are also developing a new payload, i.e. equipment and software carried by the satellite.
