The employment of GNSS (Global Navigation Satellite System) services and positioning techniques in numerous fields such as maritime, aviation, terrestrial navigation and geodetic survey, have led to a continuous scientific research with the aim to improve the accuracy and precision of the positioning techniques. Currently, GNSSs are providing new services for enabling Precise Point Positioning worldwide. In this framework, the new Galileo High Accuracy Service (HAS) is a fundamental element. It provides to users orbit, clock and measurement correction leading to decimeter level positioning in real time application. This study focuses on the analysis of the benefits of HAS corrections application in different positioning models including code and carrier phase observables. The considered models exploit GPS data, and performance are assessed using dual frequency data collected by a low-cost receiver.

Abstract

The employment of GNSS (Global Navigation Satellite System) services and positioning techniques in numerous fields such as maritime, aviation, terrestrial navigation and geodetic survey, have led to a continuous scientific research with the aim to improve the accuracy and precision of the positioning techniques. Currently, GNSSs are providing new services for enabling Precise Point Positioning worldwide. In this framework, the new Galileo High Accuracy Service (HAS) is a fundamental element. It provides to users orbit, clock and measurement correction leading to decimeter level positioning in real time application. This study focuses on the analysis of the benefits of HAS corrections application in different positioning models including code and carrier phase observables. The considered models exploit GPS data, and performance are assessed using dual frequency data collected by a low-cost receiver. The obtained results show an enhanced navigation solution mainly in the vertical channel.
