Abstract
A system for measuring the earth's magnetic field includes a magnetometer and apparatus for maintaining a predetermined magnetometer tilt in the magnetic meridional plane regardless of changes in vehicle heading. The magnetometer is of the type whose optimum measurement sensitivity is defined by a cone of predetermined angle that is symmetric about its optical axis. It is engaged to a planar platform by gimbal apparatus forming orthogonal axes of rotation that cooperates with a rotatable hemispherical strip to allow the magnetometer to be continuously repointed during changes in the heading of a carrier vehicle so that it is maintained in the magnetic meridional plane at a predetermined tilt angle.
