WAAS uses a network of ground-based reference stations to measure variations in the GPS satellites' signals in the western hemisphere. Measurements from the reference stations are routed to master stations and send the correction messages to geostationary WAAS satellites. Those satellites broadcast the correction messages back to Earth, where WAAS-enabled GPS receivers use the corrections while computing their positions to improve accuracy.
The new safety computers will become part of the WAAS operational baseline; replacing the existing safety computers and providing the resource capacity necessary to perform the safety computer functions allocated in the WAAS architecture, now and in the future. Verocel has prior experience in developing the certification materials for the existing WAAS safety computer, and is also the sole developer of DO-178B certification packages for the operating system (Wind River VxWorks) currently used in WAAS.
