  • SYSTEM AND METHOD FOR HEADING ERROR CORRECTION IN A PULSED RB-87 MAGNETOMETER AT GEOMAGNETIC FIELDS
    Publication number: 20220221277
    Abstract: According to various embodiments, a method for reducing heading error in a magnetometer that uses Rb-87 atoms is disclosed. The method includes varying a direction and magnitude of a magnetic field at different spin polarization regimes. According to various embodiments, a magnetometer adapted for reduced heading error is disclosed. The magnetometer includes a multipass cell containing Rb-87 vapor, a pump laser operated in a pulse mode that is synchronous with a Larmor frequency, and two orthogonal probe lasers configured to rotate to vary a direction and magnitude of a magnetic field at different spin polarization regimes.
