Note that the orientation zones show in Figures 6 through 9 overlap one another by 10º of
magnetic inclination. In these regions of overlap either of the recommend orientations
may be used. Also, note that in the equatorial region there are two different recommended
sensor orientations. In this region the magnetic field is nearly horizontal and there will be
some restrictions on the direction of flight. Choosing one of the two recommended
orientations will allow you to choose flight directions most suitable for your survey area.
Figure 7. Polar latitude zones.
The diagram to the left shows the
recommended sensor orientation for
operation in polar latitudes. This zone
is shown as the shaded regions above
and includes those areas where the
absolute inclination of the Earth’s
magnetic field is greater or equal to
65º. There are no restrictions on the
direction of travel when using this
sensor orientation.
