What will be tested?
The SBAS test-bed will assess three specific technologies:
Single frequency service SBAS, which is equivalent to WAAS (USA SBAS) and EGNOS (Europe SBAS). This technology will improve positioning of stand-alone GPS from 5 metre accuracy to better than 1 metre accuracy.
Dual frequency/Multiple Constellation SBAS. This is the so-called next generation SBAS and will exploit the recent development of a civil frequency, known as L5 for GPS and E5a for Galileo. This capability will demonstrate significant performance improvements over single frequency SBAS, particularly in regions with dynamic ionosphere.
Precise Point Positioning (PPP). PPP is a method that provides highly accurately position solutions with accuracy better than 10 centimetres.

Will the SBAS test-bed be certified for aviation?
... IFR SBAS capable avionics will ignore the test-bed signal.
