The first results in the design of an automatic DIM are presented. This instrument should be completely operational in 3 years. By associating it with other instruments which are already automatic, like variometers and proton magnetometers, it will be possible to install absolute magnetic observatories, all around the Earth, even in inaccessible places like on islands and on the ocean floor, since there is no need for an operator or maintenance. Automation is difficult because several key components generate considerable magnetic disturbances. Solutions to carry out the operations of rotation of the sensor, precision reading of the angles, and the pointing of an azimuth reference without disturbing the magnetic field, are proposed
