It look like something Doc Brown would be working on in his garage, but it is absolutely one of the most essential and sensitive technologies found on many military and some civilian aircraft today: ...

Even at sea, GPS signals are increasingly at risk of being disrupted by electronic warfare measures. To combat the problem, the Navy is upgrading its inertial gyrocompass navigation system for surface ...

CHARLES DRAPER, WHOSE EPONYMOUS LABORATORY developed the guidance systems for Apollo spacecraft, referred to inertial navigation as “astronomy in a closet.” It is based on a celestial reference system ...

A revolutionary new study led by Technical University of Munich and University of Bonn scientists has succeeded in measuring the subtle wobble of the Earth’s axis without using complex radio astronomy ...

After 30 years of painstaking development, researchers in Germany and New Zealand have unveiled a laser gyroscope that can track fluctuations in Earth’s rotation in near real time and accurate to ...
