Interference Mitigation

NovAtel receivers track GPS, GLONASS, BeiDou and Galileo on several frequencies in order to achieve the precision and performance we are known for. Other devices operating in the increasing crowded radio frequency spectrum can routinely cause unintentional interference within the GNSS signal bands. To combat interference NovAtel has developed the Interference Toolkit for our receivers to measure the RF spectrum levels and apply mitigation tools to protect the GNSS measurement quality. This maintains high-quality multi-frequency multi-constellation positioning performance even in challenging RF environments. 

Highlights

  • Easy to monitor, quantify and remove interference sources impacting receiver performance
  • Manually implement and manage digital filters to remove interference
  • Use automatic mode for intelligent interference detection and mitigation
  • Before/after performance indicators show digital filter effectiveness
  • Included on all OEM7® platforms
