Abstract:	The design of the future Global Navigation Satellite Systems should be oriented to the mass market. Neither GPS nor Galileo will be able to satisfy requirements of users under stringent masking conditions (like users in urban environments) or very demanding integrity requirements without additional augmentation systems. This is a major drawback for each of the systems that will have to be overcome by using additional means and therefore increasing not only the cost of the system but also the cost of the user equipment. Another possibility will be to use simultaneously Galileo and GPS; this option will be investigated thoroughly in this paper. The major benefits of the integration of GPS and Galileo will be presented and supported by simulations.
