Tests run by the EU Agency for the Space Programme (EUSPA) have concluded that Galileo's High Accuracy Service (HAS) is suitable for precision agriculture, according to a report by GPS World.

The result matters for growers because Galileo HAS delivers high-accuracy corrections free of charge, a contrast with the subscription-based RTK and correction services that many European farmers currently pay for when running auto-steer, controlled-traffic and section-control equipment. If HAS corrections hold up at field-work accuracy levels, machinery guidance costs could fall without changing hardware.

HAS is a service of the Galileo satellite navigation system, operated under EUSPA's oversight, that broadcasts high-accuracy corrections to receivers across Europe. Its target performance sits at decimeter level, the accuracy band that precision-ag applications such as pass-to-pass autosteer and yield mapping require.

What did the EUSPA tests show?

The testing program assessed how HAS performs under the conditions precision-agriculture work imposes: moving machinery, varied terrain, and continuous receiver operation across long working days. According to GPS World, the tests demonstrated that the service meets the demands of agricultural use, marking HAS as a practical option for farm navigation rather than a laboratory capability.

For equipment makers, the finding opens a path to certify Galileo HAS as a correction source alongside cellular RTK and satellite-based augmentation systems already supported on tractors, sprayers and harvesters from major manufacturers.

Why does a free high-accuracy signal matter for farm margins?

Guidance and correction services are a recurring line in precision-ag budgets. Growers who rely on network RTK typically pay annual subscription fees per receiver, while satellite correction subscriptions add similar costs. A no-fee, publicly funded alternative from Galileo would change that arithmetic, particularly for farms operating multiple machines or working in regions with patchy cellular coverage where network RTK connections drop.

The EUSPA result also fits the EU's policy push to make European satellite infrastructure a working tool for the bloc's agricultural sector, alongside the Copernicus Earth-observation program that underpins the CAP's satellite-based area monitoring.

What comes next?

The test outcome positions Galileo HAS for wider rollout across agricultural equipment and receivers in Europe. Wider adoption will depend on receiver manufacturers integrating HAS support and on farmers verifying performance against the paid services they use today — but the EUSPA tests establish that the free signal can do the field work.
