With over 10 years of experience in high-precision receiver design, Ashtech has developed an OEM GPS +SBASTM receiver explicitly for the aviation industry. The SkyNavTM GG12WTM is ideally suited for 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 SkyNav GG12W design team has adhered to all FAA/RTCA design criteria.
The SkyNav GG12W software has been developed in accordance with the requirements for RTCA DO-178B Level 'B' (Software Considerations in Airborne Systems and Equipment Certification). The hardware and software have been developed to conform to the RTCA DO-208 (MOPS for Airborne Supplemental Navigation Equipment Using GPS) and RTCA DO-229D (MOPS for GPS/WAAS Airborne Equipment) requirements. The receiver capably operates in autonomous or SBAS differential mode, making it ideal for all phases of flight, including precision approach. It also provides code and carrier data for ground reference station operation.

The SkyNav GG12W receiver features extensive anti-jamming capabilities in the RF hardware.
The receiver meets the CWI (Continuous Wave Interference) specification from RTCA DO-208 and DO-229D (WAAS MOPS).
The SkyNav GG12W GPS board incorporates all-in-view tracking of up to 12 satellites plus 2 SBAS satellites with a loss of lock re-acquisition time of less than 3 seconds.
EvaluateTM software is available with the SkyNav GG12W and provides visual displays of satellite information, receiver position and velocity, as well as data logging and analysis. It also allows direct communication with the receiver. Compatible with most Magellan professional receivers, the software runs on Windows® version 3.x Windows 95/98 and Windows NT, 2000 and XP platforms.
