A real time directional orientation apparatus is disclosed for use in a four pi (4 pi ) geometry. The apparatus is to be affixed to an object which translates in space. A source emitter means, which may be radioactive, is suspended in a fluid in concert with a magnet. A bank of emission detectors registers the orientation of the source emitter or emitters against a known starting value. As the object translates in space, so does its position and orientation, thus causing the magnet to adjust its position in reference to an external magnetic field, such as, but not limited to, the earth's magnetic field. The motion of the magnet causes the emitter or emitters orientation to change which is sensed by the emission detectors as both a change in intensity and position. This data is processed by a computer and with ancillary data provided by other sensors provides real time position, path and other navigational, directional and positional data, such as pitch, yaw, attitude and roll.
