GNSS II: Imperative for Galileo-GPS Rationalization and Harmonization

R.W. Skinner

Abstract:	The European Union has set a course for the development of a European Space-based Navigation System called Galileo. Protracted government-to-government negotiations have failed to reach agreement on an objective level of interoperability between the existing Global Positioning System and Galileo. Despite a longstanding declaration of civil focus and control, Galileo has even suggested co-mingling some of its services in that portion of the radio spectrum proposed for GPS military operations. Such a decision would almost certainly complicate the U.S. approach to meeting its policy on Navigation Warfare and could even in the end mean interference to both GPS and Galileo services in some operating scenarios. The paper examines both Galileo and GPS programs and proposes the minimal set of conditions for harmonization. The paper also suggests increased levels of harmonization that could result in combined GPS and Galileo operations at higher levels of performance than either single constellation could attain.
