Orienting Your CS-3Sensor Inclination 67.5°Sensor azimuth values used in Figure 8 are 0, 90, 180 and 270 degrees.Please note, that the sensor azimuth may differ from the flight directionazimuth, as the sensor axis may have to be set out of the airplane axis. Forexample, if the line (flight) direction is NE, and the sensor azimuth is to be90°, then the sensor axis is to be rotated by 45° clockwise from the airplaneaxis. The particular sensor orientation shown in Figure 8 does not offer anyadvantages.Figure 8 - Plot of tumble angle versus magnetic fieldinclination. Sensor inclination is 67.5°. Sensor azimuths are0, 90, 180 and 270 degrees.A more advantageous orientation is one with the same sensor inclination, butdifferent azimuths, Figure 9. Large areas extending from either pole down tothe field inclination of 25° could be surveyed using this orientation.However, the operation is at the edge of the active zone for the magnetic fieldinclinations around +/-75°.3-10CS-3 Manual - part # 762701 Revision 2.0
