New GNSS signal quality monitoring service for safer Finland is under development

Researchers are creating a GNSS signal quality monitoring service. It is tailored to meet the requirements from Finnish Transport Safety Agency (Traficom) as the target stakeholder of the offered service. With the service, it will be easier to monitor interferences in GNSS signals.

Alert messages in case of signal anomalies

‘The main objective is to offer a nation-wide 24/7 GNSS signal quality monitoring service by utilizing the national FinnRef reference stations,’ says Research Manager Zahidul Bhuiyan from the Finnish Geospatial Research Institute.  

The service is implemented in the frame of a new project entitled ‘Implementation of GNSS-Finland service (GNSS-Finland Service)’. It 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. 

A prototype already made

This new project is the successor of the project ‘GNSS-Finland (GNSS Signal Quality Monitoring in Finland)’ that ended in June 2019. 

‘In the “GNSS-Finland” project, we built a prototype software that shows the true potential of a nation-wide service in terms of monitoring GNSS signal quality data as perceived by the national FinnRef reference stations,’ says Dr. Zahidul Bhuiyan.

The “GNSS-Finland” project demonstrated that the service once offered to the general public will encourage the uptake of European GNSS (EGNSS), foster business in this domain, and offer first-hand monitoring status of GNSS over Finland. 

The new project is funded by Traficom. It started in November 2019 and it will end in October 2020.
