NovAtel’s next generation of WAAS receiver, the WAAS Reference Receiver G-II, benefits from NovAtel’s newest technology to provide exceptional tracking performance, advanced integrity monitoring, and improved multipath rejection for Satellite-Based Augmentation Systems (SBAS).


Product Datasheet

Superior tracking ability

Designed to meet demanding performance requirements, the WAAS G-II incorporates NovAtel’s patented Narrow Correlator® tracking technology. With low angle satellite tracking and fast reacquisition, Narrow Correlator® enhances the reception of satellite data for highly accurate range measurements. In addition, NovAtel’s patent-pending
SafeTrak™ algorithm increases reliability by detecting
and eliminating cross-correlation.

Improved multipath elimination

NovAtel’s WAAS reference receivers lead the world in multipath mitigation with our patented MEDLL® technology. Now, enhanced algorithms and increased RF bandwidth provide a 50 percent improvement in MEDLL performance. As a result, the WAAS G-II provides the most accurate reference signal measurements available.

Signal quality monitoring

The WAAS G-II also offers Signal Quality Monitoring (SQM) measurements to monitor the quality of the incoming signal and detect satellite failures. Multiple correlators provide real-time data to conduct satellite signal quality monitoring over the full ICAO threat space.

Exceptional interference rejection

The WAAS G-II incorporates nearly ten years of technical innovation developed for SBAS networks around the world. This research has resulted in superior protection against RF interference, which is often found in areas with high communication traffic such as air traffic control centers. This includes digital pulse blanking on the L2 signal to mitigate against in-band interference from radar and pulsed DMEs.

Future expandability

While providing today’s leading edge technology, the WAAS G-II has the added advantage of expandability for the future. With the capability to hold up to 12 Euro form factor cards in three independent receiver sections, the WAAS G-II is ready to support additional receiver cards for tracking such signals as GPS L5 and L2C, Galileo, and GLONASS. As a result, the WAAS G-II is ready for the future in the world’s wide area reference networks.
