How can aerial drones avoid aircraft loss and take home

Now UAV aerial photography is becoming more and more popular, many friends around have played aerial photography, but there are also a lot of problems when UAV aerial photography is inevitable, the most important problem is UAV flight loss, Today, talk about the common reasons for UAV flight loss?

1. Reentry Point Setting:

 There are many pilots in the UAV return orders, but the UAV does not know where to go. In fact, this kind of problem is caused by taking off without waiting for the prompt return point to be refreshed before taking off. Therefore, before each aerial photograph, we should confirm that the return point is recorded and then take off. When the flying hand needs to leave the return point due to the shooting demand, it should also set up a new return point position in time. During the return of the UAV, we should look at the map of the APP. If the aircraft does not fly to its own place when it returns, cancel it at the first time and reset its position as the return point.

 2. Electricity issues:

 Dajiang and other manufacturers promote UAV life, the premise is the ideal environment. In fact, because of wind and resistance problems, it is possible to fly short time. Therefore, to prevent the loss of power: watch the electricity, do not fly too far. The aircraft will calculate its own electricity, if the electricity is very low, the aircraft to a certain amount of electricity will be forced to drop. Prompt the return to return in time.

 3. Impact during filming:

 Hit an obstacle while shooting left or right or rear. to prevent this situation. Try to fly higher and observe the altitude before flying. 2 is to rotate a circle in the horizontal flight front on the map to see the height. If you exceed the horizon, try to get the aircraft moving forward. Don't fly too fast, otherwise it's too late to avoid the line.

 4. Backward impact:

 If the aircraft loses the signal behind the building or mountain, the aircraft triggers the return, and the altitude of the return does not exceed the height of the obstacle, and the aircraft will hit when it returns. In this case, most of them fly around the back of the building, the map is lost, the remote control signal is lost, and the altitude of the aircraft is not enough. Therefore, in flight, it is best to look at the flying environment first. If there are tall buildings or mountains, it is recommended that the altitude of return should be set higher, P4 there are obstacles to avoid. But can not avoid small objects and buildings above restricted altitude at night.

5. wind blows:

 Generally, because of the high wind speed weather, in the process of returning, because of the headwind flight, the UAV flight speed will be particularly slow, power consumption will also increase, resulting in unable to fly back to the return point. Therefore, in aerial photography flight, we must pay attention to the APP on the wind speed tips, if too large, should try to avoid flying or should not fly too far, and reserve sufficient electricity to return.

6. through bridges or other narrow spaces:

 This is a dead rhythm for some people, because if you cross the bridge, the bridge will block the signal, and even if you operate on the bridge, the bridge deck will block the remote control signal. Generally speaking, there are three situations: loss of GPS signal, loss of remote control signal and loss of map transmission signal. If only one is lost, such as a map transmission signal or a missing GPS signal, then this is saved and can fly over the bridge, but if the remote control signal is lost and the GPS signal is lost, the aircraft will fall directly to the water. Therefore, prevention, do not wear the bridge, even if the bridge, must ensure that the aircraft to the bottom of the bridge is not blocked remote control signal!
