A Characterisation of GNSS Positioning Error Vector Bearing During the Intense Space Weather Disturbance

Satellite navigation is enabled technology for a growing number of technology and socio- econimic applications. A roburst and accurate assessment of the GNSS positioning performance is required in order to assist the definition of Quality of Service for GNSS-based applications, and to allow for the identification of GNSS positioning performance deterioration. Here the Positioning Error Vector Bearing (PEVB) is introduced as a new indicator of GNSS positioning performance is proposed, that efficiently and accurately indicates GPS positioning performance deterioration due to geomagnetic effects.
