Abstract: With the corrections transmitted through its E6 signal, Galileo High Accuracy Service (HAS) provides the information required to run a standalone Precise Point Positioning (PPP) algorithm in real-time. The corrections currently cover the satellites orbits, clocks and code biases for both the Galileo and GPS constellations and are provided free of charge. The service, once fully operational, is targeting an accuracy of 20 and 40 cm (at the 95%) in the horizontal and vertical channels, respectively. Most of the state of the art literatures are dedicated to the analysis of the HAS performance in static conditions and in open-sky signal reception scenarios. On the other hand, this work focuses on the presentation of the results concerning a set of tests in static and dynamic conditions including open-sky and urban canyon scenarios. The tests have been performed using different grades of Global Navigation Satellite System (GNSS) receivers from low cost to high hand devices. The analyses performed show that the introduction of the HAS corrections leads to a sensible reduction of the positioning error in all the different environments. Interesting results regarding the HAS message availability are also presented, especially for the harsh environments scenario.
