GNSS specialists

The Finnish Geospatial Research Institute (FGI) is the leading specialist organisation on GNSS in Finland.

A Global Navigation Satellite System (GNSS) offers an easy way to determine place, speed and time. Today, satellite positioning is used in many everyday functions. The development has been rapid during the past few years: old systems are being renewed and many new systems, such as the European Galileo, are about to be completed. The development of receivers has also been fast, from small chips to large base station receivers. Smart traffic and the Internet of Things have for their part advanced and accelerated the development.

Applications of satellite positioning include:

  • Traffic and logistics on land, at sea and in the air
  • Time and the synchronisation of time
  • Internet of Things (IoT)
  • Land surveying and mapping
  • Coordinate systems
  • Spatial data
  • Recreation (e.g. exercise, hiking, games, finding targets)

The Finnish Geospatial Research Institute’s researchers have expertise in all areas of satellite positioning from signal processing and navigation to extremely precise coordinate determination.  

Our goals are:

  • Conducting scientific research in the different areas of satellite positioning
  • Producing independent data on satellite positioning and its possibilities for the society and companies
  • Supporting companies and the society and collaborating in questions related to satellite positioning
  • Awareness of the coordinate systems of different positioning systems and those used in Finland
  • Sharing information


This project will identify and analyse the role of Aurora SNOWBOX as a key infrastructure in the Nordic Hub of the Arctic PNT Innovation Platform, especially with regards to positioning and navigation needs for autonomous driving in Arctic conditions.

Establishment of a Framework Partnership Agreement for the Galileo Reference Centre support from Member States (GSA/GRANT/04/2016)

For the integrated Galileo performance monitoring and analysis activity, the consortium makes a coordinated effort to measure the Signal in Space (SiS) of individual Galileo satellites at Radio Frequency (RF) level, using a 25m radio-telescope operated by ASTRON and in parallel using a 25m radio-telescope operated by OSO, allowing for detailed interferometric analysis of the SiS, resulting in accurate localization of the phase center of the transmit antennae of the satellites.

GNSS signal quality monitoring in Finland (GNSS-Finland)

GNSS-Finland (Global Navigation Satellite System signal quality monitoring in Finland) will use the Finnish National GNSS network ‘FinnRef’ in first-hand monitoring of the status of GNSS signal quality over Finland. A prototype information infrastructure will be developed for interference monitoring capability based on recorded FinnRef data, in order to offer near real-time information of the perceived GNSS signal quality in Finland.

The Finnish Geodetic Institute studies crustal deformations at the candidate sites for final disposal of spent nuclear fuel. The project started when the research networks were founded in Olkiluoto, Kivetty and Romuvaara in 1994-1995.  The networks consist of concrete observation pillars used for periodical GPS campaign measurements of coordinates.

Finalising surveys for the Baltic motorways of the sea (FAMOS Odin)

Reliable surveyed shipping routes are a major pillar of the marine transport infrastructure and a precondition for the safety of navigation at sea. The FAMOS project aims to improve the safety of marine transport by improving the depth data in the Baltic Sea. With improved bathymetry information transport routes can be better optimized for fuel efficiency. Under Keel Clearance awareness is improved by more reliable depth calculations.

Standardisation of GNSS Threat reporting and Receiver testing through International Knowledge Exchange, Experimentation and Exploitation STRIKE3

GNSS is being used for an ever increasing range of safety, security, business and policy critical applications. GNSS functionality is also being embedded into many parts of critical infrastructures. At the same time, GNSS vulnerabilities are being exposed and threats to denial of GNSS service are increasing.
