Catalco GTK-R07 Aeronautical Geophysical Industry Solution
The optically pumped magnetometer is a magnetometer based on the Zeeman splits generated by helium and other gases and atoms of alkali metals such as potassium, rubidium, and cesium in the external magnetic field, and developed using optical pumping and magnetic resonance technology. The optically pumped magnetometer is the most accurate magnetometer among mature commercial general field magnetometers. In order to be suitable for drone flight,GTK-R07Rubidium optical pump aeromagnetic measurement systemA chip-level atomic optical pump magnetometer implemented using micro-electromechanical technology integrates a high-precision fluxgate three-component magnetometer,GPS, laser altimeter, 9-axis attitude sensor, barometric altimeter, use the industry's mature fixed-wing aeromagnetic compensation technology, real-time or post-flight compensation methods to eliminate the interference caused by the aircraft to the magnetometer probe during maneuvering flight using software compensation method. This system is currently the lightest vertical-fixed-wing drone optical pumping aeromagnetic compensation system known commercially.
