Fly your drone safe and avoid flyaway!
The GPS module in drones has a built-in magnetic
field sensor for measuring the geomagnetic field, which is not the same in all
areas. The GPS module will not work unless the Compass Module has been
‘Flyaway’ can be avoided if you care your drone
well. Just do the ‘geomagnetic calibration/compass calibration’ before each
flight especially if you are flying in a different area. To keep the compass
module away from magnetic objects, you MUST do the compass calibration. Otherwise,
it may damage the compass module and lead the aircraft to work abnormally or
even be out of control. Make sure to keep away from other electronic equipment
when calibrating and flying. If calibration failures continue, it might suggest
that there is magnetic interference or material in the area and you should
consider avoiding flying in that area.
If your drone is hovering in a circular pattern or
flies to the left when attempting to fly straight forward, or to the right if
you are trying to fly backward, then you have a clear sign to re-calibrate the
Avoid flying near high-tension
power lines, cell phone antennas or microwave antennas.
They are known to interfere with communication between the transmitter and
receiver which may make your drone sick and flyaway!
Fly with GPS
GPS is used by your drone to fly autonomous missions with the mobile app
such as way point mode, orbit mode, follow me mode and to know its position in
space. If you do not reach the minimum amount of GPS signals required to take
off, you will not be able to take off and start the mission. GPS signals can be
disrupted by many things such as mountains, foliage, cloud cover, etc. The GPS
also communicates with the compass. The compass allows the drone to know its
heading or direction in space. If the compass has not been calibrated, the GPS
will not allow the drone to initiate a mission. The compass has an internal
magnetometer that can be affected by things like reinforced concrete,
buildings, and antennas. These are all considerations to take into account when
choosing a place to plan a mission, and more importantly where to start the
