"The question remains; how would the multi-rotor or ANY drone which uses a magnetometer for yaw control be affected by close proximity to the magnetic pole(s), and whether or not that is an issue. Multi-rotors use the compass for the yaw sensor; yaw…"
"Does a compass work at the poles? Is the magnetic field too strong and out of range of a typical 5883 clone mag chip? Is it affected in real-time by the charged particles from the Sun (auroras [north pole])? Drones typically use a compass ( HMC5883…"
"Additionally, if you are using the AK8963 (which is also embedded in some Invensense chips), you might want to switch to a 5883 clone component. I have used this part in my drone for YEARS with no problems. Note it is critical to not have any stray…"
Technical note regarding compass chips (magnetometers); most drones are using magneto-resistive magnetometers like the Honeywell 5883/5983, and not Hall effect sensors. One of the most common Hall sensors, the AK8963, has been…"
