Pesticides and fertilisers can be important tools in modern farming. When used correctly, fertilisers provide essential nutrients for crop growth, while pesticides can help protect those crops from harmful pests and diseases.

The Galileo Open Service (OS) and the Enhanced Search and Rescue (SAR)/Galileo Service Performance Reports of the third quarter of 2022 (covering July, August, and September) are now available.

The Galileo High Accuracy Service (HAS) is now operational offering unprecedented accuracy for positioning.

The Galileo OSNMA SIS ICD and the Galileo OSNMA Receiver Guidelines have been published. They specify the baseline applicable to the OSNMA service provision phase that will start after the OSNMA Service Declaration. Its publication allows the OSNMA user community to prepare for the OSNMA service provision phase in advance of the OSNMA Service Declaration.

The Galileo Open Service (OS) is being upgraded with three new features being added to the I/NAV message, which is one of four message types broadcast by Galileo satellites. Collectively referred to simply as I/NAV improvements, these features will be available free of charge to all Open Service users.

The Galileo Open Service (OS) and the Enhanced Search and Rescue (SAR)/Galileo Service Performance Reports of the second quarter of 2022 (covering April, May, and June 2022) are available at the Electronic Library of the European GNSS Service Centre web portal.
