Orienting Sensor Inclination 0° The orientation below is not acceptable, as the tie lines are in dead zones. 4—15 Figure 15 - Plot of tumble angle versus magnetic field inclination. Sensor inclination is 0°. Sensor azimuths are 0, 90, 180 and 270 degrees. The orientation shown below has the advantage of covering the entire Earth except the polar regions. For large area, up to the field inclination of +/-45°, the sensor operates far from the dead zones, but the sensor operating hemisphere has to be changed when the flight direction is reversed.

Orienting 4—16 Figure 16 - Plot of tumble angle versus magnetic field inclination. Sensor inclination is 0°. Sensor azimuths are 45, 135, 225 and 315 degrees. Recommended Survey Orientations Only two orientations are sufficient for surveying along two sets of perpendicular lines over the entire Earth's surface: 1. The orientation in Figure 11, with the sensor inclination 45° and azimuths 45, 135, 225, 315 degrees, for polar and equatorial regions, and 2. The orientation in Figure 7 with sensor inclination 90 degrees, for the regions between polar and equatorial regions. These orientations provide enough overlap at both ends: regions with field inclinations N/S from 53° to 75° and inclinations N/S from 10° to 22° could be surveyed by either sensor orientation setting 1) or 2). In the overlap regions the tumble angle comes close to boundary of the dead zones. For a larger safety margin following alternate orientation is strongly recommended: 3. The operation around the magnetic equator, extending well into the regions with the magnetic field inclinations up to 45°, could be covered with the sensor inclination 0° and azimuths 45, 135, 225, 315 degrees (see Figure 16). If the above three orientations are used in both Earth's magnetic hemispheres as follows: • the orientation a) for the field inclinations from 60° to 90° • the orientation b) for the field inclinations from 35° to 60° P/N 763701 Rev. 1
