Galileo High Accuracy Service Information Note is now available
The European GNSS Agency (GSA) and the European Commission (EC) have published the Galileo High Accuracy Service (HAS) Information Note, providing an overview of the Galileo HAS service, covering characteristics and features such as service levels, target performance, implementation roadmap, milestones, and an overview of addressable markets.
Galileo HAS is a free of charge, high-accuracy Precise Point Positioning (PPP) correctional service in the Galileo E6-B data component, providing improved real-time user positioning performance with a positional error of less than two decimetres in nominal conditions.
HAS is one of the four high-performance services provided worldwide by Galileo alongside the Galileo Open Service (OS), the Public Regulated Service (PRS), and the Search and Rescue Service (SAR). Galileo HAS provides an additional navigation signal and added-value services in a different frequency band. The HAS signal can be encrypted in order to control access to the Galileo HAS services.
The HAS information note covers the type, format, and dissemination of corrections, supported constellations and frequencies, horizontal and vertical accuracy, the availability, and even the user helpdesk availability for both global, service level one, and the European Coverage Area, service level two.
Following the definition of the characteristics, the information note provides an overview of the high-level architecture, the roadmap to the full service, and it provides information to further information such as the E6-B/C technical notes, helpdesks, market reports, and much more.
