The Galileo High Accuracy Service (HAS) Reference Algorithm Technical Note is now available. It provides the definition of the soon to be published Galileo HAS Reference User Algorithm, aiming at supporting users in developing and testing its implementation.
Are you a current or future user of the Galileo High Accuracy Service (HAS)? We´ve got great news for you!
To support the implementation and/or testing of Galileo HAS corrections at receiver level and the development of applications – whether based on the Internet Data Distribution (IDD) or E6B Signal-In-Space (SIS) –, the Galileo HAS Reference User Algorithm Technical Note is now available. It includes the algorithm description, assumptions and mathematical formulation to facilitate the algorithm use and implementation.
The Technical Note serves as a helpful tool for users interested in implementing the Galileo HAS Reference User Algorithm. EUSPA remains available through the GSC helpdesk to address any questions or suggestions which will be gathered over the coming months to further improve the practical application of the Galileo HAS Reference User Algorithm in the future.
The Galileo HAS Reference User Algorithm software will enable a real implementation of the formulation provided in the Technical Note and will soon be available on the GSC website. It is a real-time PPP algorithm that exploits the HAS corrections to generate a Position, Velocity, Time (PVT) solution in line with HAS Minimum Performance Levels (MPLs) and typical positioning performance specified in the HAS Service Definition Document (SDD). It is intended to assist each HAS user interested in implementing or using the HAS User Algorithm to obtain a HAS PVT but alternative algorithms based on the same principles could be used.
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.
