Abstract:	The development and deployment of a SBAS system in any region of the world is not a simple task. The development of the current operational SBAS systems has required significant time and effort. Besides, each region may have different characteristics and requirements. The ionosphere behavior is, for instance, a key issue for implementation of an SBAS in some regions. It is usual that SBAS development plans envisage the deployment of SBAS testbeds (e.g.; WAAS NSTB, EGNOS ESTB) and pre-operational, non-certified, services in parallel to the operational system development. Testbeds provide the system developers with powerful platforms to validate architecture, design and performance assumptions. Testbeds also permit users to benefit from early SBAS services, representative of the final augmented performance and useful in many applications (e.g.; precision agriculture) which do not require a formal certification process. Even for aviation users, which required a certified system, a testbed is a very useful tool to better understand and demonstrate to the relevant communities the operational benefits of the SBAS solution. However, despite the numerous advantages, the development of an SBAS testbed is also a complex task which has taken years in the case of WAAS and EGNOS. This paper presents the current status and performance of magicSBAS, a SBAS operational testbed developed by GMV that permits to deploy a pre-operational SBAS service and experimentation platform anywhere in a very short time frame and with a reduced cost. magicSBASincorporates all the experience gained by GMV in the development of EGNOS and other SBAS in different regions.
