Magnetometers Calibrations and the Inertial Labs INS-P

Magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. Though phonetically complex, magnetometers can be common devices used in everyday life such as compasses and metal detectors. In general, there are two basic types of survey magnetometers: vector and scalar magnetometers. Vector magnetometers measure magnitude and direction of a magnetic field. Alternatively, scalar magnetometers measure the absolute or vector magnetic field, using an internal calibration or known physical constants of the magnetic sensor.
