Introduction
There are two sets of International Standards which SBAS’s shall be compliant in order to be used by Civil Aviation Authorities:
- The Standards and Recommended Practices (SARPS) Standard for SBAS systems established and controlled by the International Civil Aviation Organization (ICAO)[1] and which provides Standards regarding the type and content of data which must be generated and transmitted by an SBAS system. In general, the SBAS provider shall broadcast a SBAS Signal in Space (SIS) compliant to this standard in terms of radio-frequency characteristics, and data content and format.
- The Minimum Operational Performance Standard (MOPS) DO229 established and controlled by the US Radio Technical Commission for Aeronautics (RTCA)[2] and which provides standards for SBAS receiver equipment.
For the aeronautical user international community, the documents listed in the following table constitute the current version of the core set of documents to be used for the development of a new system devoted to provide services to these users or for the development of aeronautical user terminals.
