A Report on GPS and Galileo Time Offset Coordination Efforts

Abstract
Precise timing is an inherent part of radio navigation systems like GPS and Galileo. This paper update progress on cooperative efforts between the GPS system and the Galileo system to harmonize the underlying Navigation time scales of both systems to better facilitate a combined GPS/Galileo navigation solution. This paper also outline cooperative experimentation and demonstration that will be conducted during the Galileo development phase.
