For a detailed description of SBAS Messages, see article EGNOS Messages. This articles follows the standard described in RTCA MOPS DO-229-C “Minimum Operational Performance Standards for Global Positioning System/Wide Area Augmentation System airborne equipment” (particularly in its Appendix A “Signal characteristics and format”), applicable for every Satellite Based Augmentation Systems (SBAS). In the article, SBAS Message specification is also compliant with the ICAO SARPs “Standards and Recommended Practices”, Appendix B “Detailed technical specifications for the Global Navigation Satellite System (GNSS)”. These two standards are nearly aligned in what regards to the SBAS SiS specification, but the augmentation of GLONASS or other constellations except for GPS are not specified in MOPS, as WAAS does not provides augmentation to GLONASS satellites.
