The GEO satellites broadcasting EGNOS messages are going to be changed.
On March 20, PRN 123 (now in test) will be introduced in the operational platform, and on March 21, PRN 136 will be moved from the operational platform to the test platform.
Users equipped with non-(E)TSO-certified SBAS receivers (such as those used in agriculture, surveying, mapping and maritime, but not in aviation), it is recommended that users reassess the equipment configuration after the change, to ensure that both operational EGNOS GEO satellites (PRN 120 and PRN 123) are configured in the equipment.
More details on this change are available in the official Service Notice #15.
Depending on the receiver, users can check equipment manuals or contact product manufacturer/dealer. Guidance is provided on the EGNOS website on how to configure an EGNOS receiver for some of the most common equipment used in agriculture.
