Abstract
The paper presents results from a comparative study on the GPS performance based on experiments carried out in Copenhagen, Denmark in both 2003 and 2008. GPS data from 40 vehicles were collected to re-evaluate the GPS performance in a Danish environment and thereby assess the level of performance improvement obtainable after 5 years. The performance assessment addresses the subjects of satellite visibility and positioning quality and results from the two experiments are compared respectively. The results of this assessment show that the satellite visibility and positioning quality have improved significantly in Copenhagen during the 5 years from 2003 to 2008.
