Insight
Magnetometers flying today are usually corrected by compensation models fitted to each vehicle, a method with a long record in airborne survey.
We add a second line of defence: a sensor designed to reject the platform's own magnetic field on board, so that less is left for the model to correct.
Insight
Magnetic navigation has already flown. The next step is an instrument that tells the vehicle, at every instant, how wrong its position can be.
Insight
Jamming and spoofing of satellite positioning are part of everyday flight operations in several regions. The figures, with their sources, and what they mean for navigation.
Insight
Satellite navigation is increasingly jammed, spoofed and denied. A passive magnetic reference adds a layer that does not depend on satellites.
