Popis:	An experimental type of an airborne magnetometer is described using three mutually perpendicular saturable‐core magnetometers. Signals from two of these magnetometers are used to precess an air‐driven gyroscope so as to align its spin axis along the earth's total magnetic intensity, thus providing stabilization for the third magnetometer which can then measure anomalies of a few gammas along the line of flight. This method of stabilization permits the use of the magnetometer in vehicles subjected to the most violent angular accelerations. It can also be made smaller than non‐gyroscopically stabilized airborne magnetometers.
