Abstract:	SACCSA project Phase III’s (Soluci_n de Aumentaci_n para Caribe, Centro y Sudamérica) objective is to study the improvement of the Air Navigation Environment in the Caribbean and South America (CAR/SAM) Regions with a SBAS solution. The project is managed and internationally coordinated by ICAO (International Civil Aviation Organization) on behalf of the Participants/Member States and International Organizations that are the founders of the SACCSA Project. Phase III of the project has recently started with GMV as Prime Contractor. The main objective of this phase of the project is to perform a detailed technical feasibility analysis of the SBAS solution. For doing this, two main guidelines will be followed: on one hand a detailed study will be done to cover aspects like performances, ionosphere, communications, network topology, and on the other hand a SBAS prototype will be developed and operated aimed at complementing the analysis. This paper describes the SACCSA project phase III, and the obtained performance analysis is also shown. At equatorial latitudes, the ionospheric activity can become a significant problem on GNSS, and a critical and complete analysis will be performed focused on the impact of this atmospheric effect on SBAS systems. GPS real data will be analysed completing the study performed in the previous phase of the project, and the main preliminary results are presented in this paper. Additionally, SACCSA performances will be analyzed through simulated data tuned with real ionospheric data in the CAR/SAM Regions to obtain the expected performance of the SACCSA system in a controlled, complete and realistic environment. Ionospheric data (simulated data based on real data) will feed the EETES Simulator (End to End Egnos Simulator) to obtain a set of RINEX data for different scenarios that will be the input for SACCSA UCP prototype (Unidad Central de Proceso) that is the computational heart of a SBAS System. SACCSA prototype will be based on magicSBAS, a Flexible GMV proprietary product that includes the algorithmic SBAS and Ionosphere experience of GMV. Main available results will be presented in the paper. magicSBAS product will also be used as the core product for a SACCSA prototype (with real data) that will be operated in the region over 6 months.
