Estudio de los criterios y desafíos de interoperabilidad de SBAS a nivel mundial

Abstract

[ES] Los Sistemas de Aumentación Basados en Satélites actuales se basan en la corrección del posicionamiento obtenido mediante satélites GPS. Sin embargo, con el creciente desarrollo de nuevos SBAS basados en correcciones de señales de otras constelaciones GNSS, se plantea un problema de interoperabilidad entre los SBAS actuales y futuros. Este estudio trata de asentar los aspectos técnicos y las normativas actuales para asegurar la interoperabilidad de los SBAS actuales, así como de plantear los problemas que pueden surgir en este ámbito con la implementación futura de SBAS basados en constelaciones GNSS como GLONASS o BEIDOU.

[EN] This final degree project, A Study of the Criteria and Challenges of SBAS for Global Interoperability, presents an analysis of how interoperability has developed over the years. The current rapid growth of Satellite-Based Augmentation Systems (SBAS) is undeniable. Judging solely by the testing and certification processes of SBAS systems under development, the number of these systems in operation is expected to double in the next five years, significantly increasing the precision, integrity, continuity and availability of the underlying operations related to air navigation (and even other associated applications, such as the field of geodesy, for example). On the one hand, the project examines the implementation of the SBAS systems that are currently operational to offer services in the area of air navigation. Studying their implementation, at both the technical and the operational level, will throw light on the reasons why they can be said to be interoperable with each other. On the other hand, it comments on the current lines of research both on the implementation of new SBAS systems and on improving the performance of current systems. It will also show that these improvements will be included in the SBAS systems that are not currently operational, and SBAS will therefore have a uniform level of technological complexity and operational performance. The intention is to observe the efforts made over the years to maintain an apparently imperceptible interoperability between current and future SBAS systems.
