ForewordForewordThe CS-3 is an optically pumped cesium vapor magnetometer sensor used forscalar measurement of the Earth's magnetic field. As shown below, the CS-3sensor consists of a sensor head with cable and sensor electronics.Figure 1: CS-3 Magnetometer SensorThe system excels in a variety of applications (ex. airborne, satellite, marineand ground magnetometry or gradiometry, base station magnetometry andferrous ordnance location) due to its:• high sensitivity• high cycling rates• excellent gradient tolerance• continuous output• automatic hemisphere switchingCS-3 <strong>Manual</strong> - part # 762701 Revision 1.0i
