Geoscience Australia, Lockheed collaborate on multi-GNSS SBAS research

February 13, 2017By
To improve precision navigation, a second-generation SBAS will use signals from both GPS and Galileo, and dual frequencies, to achieve even greater GNSS integrity and accuracy.

Geoscience Australia, an agency of the Commonwealth of Australia, and Lockheed Martin have entered into a collaborative research project to show how augmenting signals from multiple GNSS constellations can enhance positioning, navigation and timing for a range of applications. Other partners are Inmarsat and GMV. The research project aims to demonstrate how a second-generation Satellite-Based Augmentation System (SBAS) testbed can... read more

Tracking RFI: Interference localization using a CRPA

Eurocontrol-airtrafficcontroller-airlines-O

A controlled radiation-pattern antenna can preserve GNSS positioning while providing at least an azimuth angle towards an interference source. If integrated with an attitude and heading reference system, only a few lines of position pointing towards the RFI source could provide a fast indication of the probable ground location. read more

Interference mitigated with CRP and dual-polarized antennas: Free webinar

January 30, 2017By
February cover story.

Two new topic areas and presentations have been added to this Thursday’s free webinar on Signal Interference: Detection and Mitigation. The speakers will explore anti-jamming protection with controlled radiation pattern antennas (CRPAs) and with dual-polarized antennas. The latter topic is also the cover story for the February issue, which demonstrated a significant improvement in positioning accuracy and robustness against interference... read more
