Specifically, NAVISAS is devoted to combine multiple GNSS constellations (GLONASS, GPS and Galileo) and a novel concept of atomic micro-gyroscope based on atomic spin and nuclear magnetic moment
precessions, and to assess the improvements in performance and security.
Every proton, by virtue of charge and spin, exhibits a small nuclear magnetic moment
([mu]) and begins to precess at a frequency referred to as the Larmor frequency ([omega]).
The sample is then subjected to electromagnetic radiation, usually in the radio frequency portion of the spectrum, at the frequency at which the nuclear magnetic moments
undergo transitions from being aligned with the field to against the field.
