Galileo High Accuracy Service

The Galileo High Accuracy Service (HAS) is a component of the Galileo system, which is the European Union’s Global Navigation Satellite System (GNSS). HAS aims to deliver high accuracy positioning and timing information globally. It is designed to support a wide range of applications requiring high precision, such as autonomous driving, precision farming, and drone navigation.
Key features of Galileo HAS include:
Free of Charge: The service is provided free of charge, making high accuracy corrections accessible to users worldwide.
High Accuracy Corrections: HAS offers corrections for orbits, clocks, and signal biases for each satellite, enhancing the precision of positioning services. In its full service, it will also include atmospheric corrections.
Two Dissemination Channels: The corrections are accessible through two main channels – the E6-B Signal in Space (SiS) and the Internet, ensuring wide availability and flexibility in usage.
Galileo HAS represents a significant advancement in GNSS capabilities, providing enhanced services for both professional and commercial applications on a global scale.
