An update of the Galileo HAS Info note has been published, introducing information regarding the ongoing enhancements aimed at enabling HAS Full Service Declaration in 2027.
The European Union Agency for the Space Programme (EUSPA) has published an updated Galileo HAS Info Note. The document provides an overview of the Galileo High Accuracy Service (HAS), covering its main characteristics and features such as service levels and target performance.
The main scope of this update is the inclusion of information about the HAS Phase 2, an on-going effort ultimately targeting the declaration of the Galileo HAS Full Service during 2027.
The Full Service envisages the provision of Service Level 1 and Service Level 2 in compliance with target performances (e.g. 20 cm horizontal positioning accuracy). To enable those, Galileo will transmit additional data with respect to current’s Initial Service, amongst others phase biases and ionospheric corrections. In addition, the service is planned to be enhanced with the provision of high-accuracy data authentication capabilities.
These and other technical details will be made available to users via the HAS Service documentation (e.g. updated ICD or user reference algorithm) that will be published on the GSC website in a timely manner, synchronized with the Full Service Declaration.
Finally, updates on the most relevant markets and applications that can benefit from Galileo HAS have been incorporated based on the lessons learnt gathered by EUSPA since the Initial Service.
About Galileo
Galileo, the EU´s Global Navigation Satellite System (GNSS), provides improved navigation, positioning and timing information. More than 4 billion users are already benefitting from Galileo.
The Galileo Programme is owned by the EU. The European Commission, as the Programme Manager, oversees the implementation of all activities. EUSPA is responsible for the operational management of the services, ensuring that they are delivered with the defined performance and without interruption. Galileo's system design and system evolution are entrusted by EUSPA to ESA.
