Service Notices

A Service Notice to Galileo Users (SNGU) is a temporal amendment to the applicable Galileo Service Definition Document. Therefore, the Service Notices are notifications published whenever there is any complementary information that could have a relevant impact in any of the Galileo Service Definition Documents’ (SDD) contents.

The classification of the Galileo Service Notices based on their corresponding status is as follows:

• IN FORCE: The Service Notice is currently in force. That means the information presented in the Service Notice is relevant and valid. Then, the Service Notice shall be used as a complement to the corresponding in-force SDD.
• SUPERSEDED: The information of the Service Notice is already included in the corresponding in-force SDD. So, although the information of the Service Notice is still valid, the Service Notice itself does not complement the in-force SDD.
• EXPIRED: The information of the Service Notice is not valid anymore. That means the information presented in the Service Notice is currently lapsed or obsolete and consequently, the Service Notice shall not be used anymore.
