The CW series Aeromagnetic Surveying System takes the lead in introducing the latest generation of high-precision micro-rubidium magnetometer, which integrates a high-precision fluxgate tri-axial magnetometer, GPS, laser altimeter, 9-axis attitude sensor, and barometric altimeter. Using self-developed patented fixed-wing aeromagnetic compensation technology, it eliminates the interference caused by the magnetometer probe during the maneuvering flight of the aircraft, obtaining high-precision magnetic total field and magnetic vector field data. In addition to the high-precision fluxgate magnetometer, the main total field magnetic sensor of this series of unmanned aerial magnetic equipment is a high-precision optically pumped magnetometer, which meets the requirements of aviation magnetic survey technical specifications.
