Abstract:	The main objective of this paper is to present the Galileo Ground Mission Segment (GMS) integrity algorithms, taking into account those aspects directly related to the Galileo user integrity concept. It includes: - Implementation of the Galileo overbounding concept at algorithmic level including the underlying processing; - Analysis of the main assumptions and hypothesis considered in the proposed algorithmic strategy; - Impact of the implementation of the safety requirements in the algorithm development; - Expected performance based on analysis, simulations and processing of real GPS data; - Impact on the algorithmic design coming from the threat models considered at System level. Details of the key design and performance drivers are provided, together with the identification of the main areas in which improvements are still expected.
