Precise positioning with SSR Galileo High Accuracy Service

This study evaluates the positioning performance of Galileo High Accuracy Service (HAS), focusing on its compliance with Service Level 1 (SL1) accuracy and convergence time requirements. The results show that all three processing centres (Centre for Orbit Determination in Europe (CODE), Centre Natio...
