Verocel to develop safety computer for Wide Area Augmentation System
WESTFORD, Mass., 27 June 2012. Verocel Inc., an independent software verification company, has received a $6.2 million single-source contract from the Federal Aviation Administration (FAA) to develop the next-generation safety computer for use in the Wide Area Augmentation System (WAAS).
-- WAAS upgrades get STC for Cessna Citation Ultras and Encores
-- Gulfstream receives certification to install WAAS on G150 aircraft
-- WAAS LPV from Universal Avionics installed on Falcon 2000 aircraft
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.
