GNSS Weather Service for Satellite Navigation Quality Evaluation

Ministry of Transport and Communications has commissioned a preliminary study (GLAS project) which charted GNSS (Global navigation Satellite System) signal users' needs and expectations regarding the quality of the signals.

A roll-out version of the quality evaluation service was also developed in connection with the study. A full version will be published later. A service user can e.g. monitor the quality of the satellite navigation signals and encounter possible interference as well as get notifications for upcoming signal disruptions.

GNSS signals are utilized in many kinds of devices and applications in various fields. For example, in the development of mobility services satellite navigation has a key role. A GNSS signal combined with e.g. 5G-technology offers a reliable method of positioning in systems such as automated driving, eCall, smart tachographs, connected vehicles, and IoT (Internet of Things).

Monitoring the quality of satellite navigation signals is essential aid for GNSS signal utilizers in their business development efforts. Up-to-date information about signal qualities helps service providers plan their operations and deal with disruptions.

The GLAS project is linked to the Government's operational programme aiming for more effective utilization of satellite navigation. The operational programme is part of a Government key project on building a growth environment for digital business. The study was commissioned by Navigation and Positioning department of the Finnish Geospatial Research Institute.
