  • Resilient Positioning, Navigation and Timing

    The Resilient Position, Navigation and Timing (PNT) research group focuses on a wide range of technologies that ensure safe and reliable use of PNT. The group utilizes unique features from Galileo (including PRS) and other GNSS signals, signals of opportunity, sensor fusion, and other alternative methods to develop solutions for resilient PNT.

Ongoing projects

  • GIMME

    One of the unique features of the Galileo satellite navigation system is its dedicated Public Regulated Service (PRS). The purpose of the PRS is to improve the resilience of authorized users against radio jamming and counterfeit signals (spoofing).

  • 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.

  • AIRING

    The project addresses resilience of aviation operations to GNSS frequency jamming and cyber (i.e. spoofing or meaconing attacks done via a GNSS signal generator) threats. The project shall assess the threats on GNSS signals and resulting risks for civilian flights. It shall develop possible monitoring techniques to detect and localise threats. The project shall also assess possible technical and operational mitigation techniques to reduce the impact of such threats on the aviation operations.

  • GNSS signal quality monitoring in Finland (FinSig)

    FinSig will use the Finnish National GNSS network ‘FinnRef’ in first-hand monitoring of the status of GNSS signal quality over Finland. A service architecture design will be developed and demonstrated, including a list of hardware, software, inter-modular communication, and system integration needs.

  • GNSS-Finland Service

    GNSS-Finland Service project will offer signal quality information in multiple frequencies for all four Global constellations, i.e., GPS, Galileo, GLONASS and BeiDou. In addition, it will offer alert messages to Traficom in case of detection of any predefined signal anomalies. Anomalies could be among other things interference on GNSS signal. This project is the successor of the project GNSS-Finland (GNSS Signal Quality Monitoring in Finland - FinSig) that ended in June 2019.
