WAAS-GII GNSS Reference Receiver

End of Life Notice: For more information, click here

The WAAS G-II provides the most accurate reference signal measurements available. 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, SafeTrak™ algorithm increases reliability by detecting and eliminating cross-correlation.

Features

  • Signal Quality Monitoring (SQM) measurements using multiple correlators
  • Includes RFI improvements developed for the US WAAS network
  • Tracks and decodes SBAS signals
  • SafeTrak cross-correlation verification algorithm
  • Digital pulse blanking on the L2 signal for mitigation against interference from radar and pulsed DMEs
  • Built-in forced-air cooling

Benefits

  • 50% improvement in MEDLL performance
  • Narrow Correlator® provides superior tracking
  • Wide range of flexible controls and configurable outputs for maximum access to satellite data
  • Expandability for future signals, such as L5, L2C, Galileo and GLONASS

Improved multipath elimination

NovAtel's WAAS reference receivers lead the world in multipath mitigation with our patented MEDLL® technology. Enhanced algorithms and increased RF bandwidth provide a 50 percent improvement in MEDLL performance.

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.
