The Ashtech SkyNav GG12W is an OEM GPS and GPS+SBAS™ receiver explicitly for the aviation industry. It is ideally suited to integration within Technical Standard Order (TSO) Flight Management Systems (FMS), ground-based reference stations for GPS aircraft landing systems (SCAT I and LAAS) and other avionics. In addition to traditional GPS receiver design and ISO 9001 engineering practices, the GG12W design team adhered to FAA/RTCA design criteria.
