SBASs: Working together

WAAS, EGNOS, GAGAN, MSAS, SDCM, K-SBAS …

All SBASs are regional systems.

The need of a seamless transition between SBAS service areas

Not only underlines the importance of adequate cooperation

But also makes issues of compatibility and interoperability critical.

The endeavors by the ICAO and SBASs

To target the development of dual frequency multi constellation SBAS by 2018

Not only may help address the ionospheric issues

But will also lead to a robust infrastructure

Enabling proper service delivery to end users and maximizing the benefits.
