Researchers at the University of Minnesota are taking a fresh look at the Falcon Gold data using some innovative analysis tools. In this quarter’s Innovation column, researchers at the University tell us about their work and its potential benefit.
How carrier-phase measurements combined with those from an inertial measurement unit can guard against a deliberate attack on an automated ground vehicle.
Mode N could meet the need for a reliable alternative PNT system for aircraft navigation. It builds on aspects of existing navigation systems and aviation-certified signals not originally intended for navigation, including some used for communications and surveillance. In this article, a team of researchers from the German Aerospace Center describe Mode N, looking at its signal format, required ground infrastructure, aircraft avionics and the potential position accuracy this system could offer.

Getting the Best in Both WorldsGPS alone won’t cut it. Thankfully, other navigation sensors can be used to supplement or replace GNSS when the going gets tough for GPS alone.
When GPS World published its first issue in January 1990, only 15 GPS satellites had been launched, including […]
Making It BetterReal-world tests show improved single-frequency GNSS positioning in urban environments using GLONASS alongside GPS, as well as the effect of different antennas and adaptive weighting of observations. Results? Single-frequency accuracies below one meter.
