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.

  • ESRIUM

    ESRIUM is a multi-national project with the common goal to set up a service to foster greener and smarter road usage, road maintenance, and to increase road safety. The key innovation will be formed by a homogeneous, accurate and recent digital map of road surface damage and road wear. ESRIUM’s core proposition is a data platform, which hosts highly detailed EGNSS-referenced map data of road damage and associated safety risks at centimeter-level resolution. Further addressed as “road wear map”, it will contain unique information, which is of value to multiple stakeholders: road operators will be able to lower the road maintenance effort by optimal planning.

  • 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 survey

    The project will carry out an investigation commissioned by the National Emergency Supply Agency (NESA), the final result of study will be a description of the provision and operation of GNSS services. The study surveys the supply of GNSS services and operators both in Finland and abroad and provides a description of the overall situation.

  • 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.

  • REASON

    Satellite navigation (GNSS) signals provide accurate and continuous position, navigation, and timing (PNT) services to citizens. These services are necessary to critical infrastructures, such as accurate timing for stock market, electricity transmission, banking and security information systems, reliable positioning for aviation, wireless communications, accurate localization for emergency (112) personnel and logistic chains, and transport.
