Abstract:	Augmentation Systems providing Integrity and Continuity services have to ensure that any user within the service area will be warn in due-time of any Misleading Information which could represent a threat for its operation. To ensure that unreliable information reach the user, integrity barriers are therefore implemented. The objective of this paper is to present a methodology for the design of such integrity barriers by consolidating and extending existing approaches. The main advantage of this method is a straight forward derivation of the minimal metric sensitivity required to fulfill the integrity and continuity requirements allocated to the barriers. An example based on the Signal Deformation Monitoring (SDM) applied in the context of Satellite Based Augmentation Systems (SBAS) is presented at the end to illustrate the proposed approach. It must be however highlighted, that this methodology is not restricted to the design of integrity barriers for SBAS systems but can be applied for other GNSS systems providing integrity services.
