The aviation research and development focused NELI research unit at South-Eastern Finland University of Applied Sciences (Xamk), is establishiFinlandPyhtää and Mikkeli. The core of these test environment consists of two ADS-B UAT ground stations. A ground station includes an ADS-B UAT transmitter and receiver unit, as well as a separate receiving antenna capable of receiving location data from various systems (ADS-B, MLAT, Remote-ID, and FLARM-like protocols on 868 MHz).
It is the first system which, along with it’s FIS-B and TIS-B services is available for installation to any European location with FIS-B information covered by Eurocontrol, as if the radio permit for the station at 978 MHz could be approved. From that point of view this is a historical moment. Even more historical this will become when in the coming week a similar system purchased by the Norwegian CAA will be installed near Oslo.
What is UAT?
Read this Wikipedia article for the ADS-B-In modes ES and UAT. UAT expands the possibilities for ground based stations providing more types of data especially for low altitude traffic including UAVs. To de-congest the ADBS-ES on 1098 MHz, UAT operates on 978 MHz which is not yet allocated in parts of Europe.
