UAV Mounted Fluxgate Magnetometer
The fluxgate magnetometer mounted on UAV (hereinafter referred to as drone magnetometer) is a series of weak magnetic measurement products integrating GPS information acquisition, attitude information acquisition, temperature information acquisition and other functions, which has the characteristics of high measurement accuracy, simple operation and convenient carrying.
The fluxgate magnetometer is composed of fluxgate magnetic sensor, data acquisition module, GPS module, attitude sensor, temperature sensor, etc. The whole set is powered by DC 7.2V/12V power supply.
Basic testing principle of magnetometer system: The fluxgate sensor converts the magnetic field signal of the area to be tested into voltage signal, and then realizes digitization through 24bit AD chip; The attitude sensor is integrated in the fluxgate sensor, and the attitude information is sent out through the serial port; The temperature sensor is integrated in the data acquisition module; The GPS module collects the GPS information of the current position and sends it through the serial port (TTL). ARM chip processes four kinds of data and communicates with the outside world through internal recording.
