Galileo High Accuracy Service: an automotive test

Abstract

The Galileo High Accuracy Service (HAS) is currently operational providing free-of-charge, Precise Point Positioning (PPP) corrections worldwide both through the Galileo signal in space and via the internet. The service increases the positioning accuracy up to few centimeters in nominal conditions. This is a key enabler for several applications including surveying, agriculture and automotive. In order to assess the positioning performance obtainable using HAS corrections an automotive test, carried out by the Joint Research Centre (JRC), has been performed. The test setup includes the HAS User Terminal (HAS UT) and different grade Global Navigation Satellite Systems (GNSSs) receivers. The performance of the HAS UT is compared with respect to PPP solutions obtained with and without HAS corrections. The performance is assessed in terms of solution availability and position accuracy for both horizontal and vertical channels. From the analysed test, it emerged that HAS UT performance is close to the PPP solutions using final precise products.
