LEGAL BASIS Regulation (EU) No 1285/2013 of the European Parliament and of the Council of 11 December 2013 on the implementation and exploitation of European satellite navigation systems and repealing Council Regulation (EC) No 876/2002 and Regulation (EC) No 683/2008 of the European Parliament and of the Council.
Call for proposals:
- Integrity is one of the essential qualities of service to be provided by the Galileo safety of life service. Advanced (A) RAIM (Receiver Autonomous Integrity Monitoring) is a possible concept to which much effort is being devoted with the intention to provide a global integrity service based on multiple satellite constellations.
- In this respect, cooperation with the United States of America was formally established through the creation of a specific EU-US ARAIM Technical Sub-Group (TSG) in Working Group C of the EU-US cooperation agreement. The ARAIM TSG has been developing the concept with a focus on Civil Aviation, including possible architectures for its implementation as well as the reference user algorithm to be implemented at the airborne receivers.
- ARAIM has different characteristics compared to current SBAS such as: using of the dualfrequency ionosphere-free pseudorange combination, not using differential corrections, enabling the use of all GNSS constellations that provide a reliable and proven Integrity Support Message (ISM).
- Two constellations are compulsory to meet minimum availability requirements globally for LPV-200 using ARAIM, which is the initial target considered by the ARAIM TSG. In addition, the possibility to achieve a less stringent performance to support Horizontal navigation only, and which can be implemented in shorter term is also being analysed.
