Orienting Your CS-3Figure 16 - Plot of tumble angle versus magnetic fieldinclination. Sensor inclination is 0°. Sensor azimuths are45, 135, 225 and 315 degrees.Recommended Survey OrientationsOnly two orientations are sufficient for surveying along two sets ofperpendicular lines over the entire Earth's surface:1. The orientation in Figure 11, with the sensor inclination 45° and azimuths45, 135, 225, 315 degrees, for polar and equatorial regions, and2. The orientation in Figure 7 on page 3-9 with sensor inclination 90 degrees,for the regions between polar and equatorial regions. These orientationsprovide enough overlap at both ends: regions with field inclinations N/Sfrom 53° to 75° and inclinations N/S from 10° to 22° could be surveyed byeither sensor orientation setting 1) or 2).3-18CS-3 Manual - part # 762701 Revision 2.0
In the overlap regions the tumble angle comes close to boundary of the deadzones. For a larger safety margin following alternate orientation is stronglyrecommended:3. The operation around the magnetic equator, extending well into the regionswith the magnetic field inclinations up to 45°, could be covered with thesensor inclination 0° and azimuths 45, 135, 225, 315 degrees (see Figure17).If the above three orientations are used in both Earth's magnetic hemispheresas follows:• the orientation a) for the field inclinations from 60° to 90°• the orientation b) for the field inclinations from 35° to 60°• the orientation c) for the field inclinations from 0° to 35°then:1. the minimum safety margin to the boundary of the operating range is 14°and it will occur for the field inclination 62°2. the safety margin less than 15° will occur only for the range of the fieldinclinations from 60° to 65°3. the safety margin less than 20° will occur for the range of the field inclinationsfrom 55° to 78°.Note:The additional allowance of 5° has been alreadysubtracted from the essential operating rangespecified by relationships (1) and (2) to arrive to thereduced operating range, relationships (4) and (5)for which the above analysis applies.Orientation3-19CS-3 Manual - part # 762701 Revision 2.0
