It is becoming more and more difficult to install satellite navigation antennas, electronic compasses, omnidirectional obstacle avoidance sensors and various communication detection antennas. The traditional remote arrangement of sensors can no longer meet the requirements. Traditional satellite antenna installation requires no obstruction and away from electromagnetic interference. Medium and large UAVs and electric vertical take-off and landing aircraft can only be installed on the top of the fuselage, but this will affect and interfere with other sensors or communication antennas, and cannot achieve a good use effect; the electronic compass needs to be installed in a location away from various strong electric and strong magnetic fields, while medium and large UAVs and electric vertical take-off and landing aircraft generally use high voltage power supply and large strong magnetic motors, and the external electromagnetic field radiation is relatively serious, so it is difficult to find a good installation location; the omnidirectional obstacle avoidance sensor requires that the detection window is as free of interfering objects as possible, while medium and large UAVs and electric vertical take-off and landing aircraft generally use distributed electric propulsion solutions, and multiple propellers are installed on each edge of the UAV. The installation of the omnidirectional obstacle avoidance sensor will interfere, and the cables are long and easily interfered with, and the cables are not conducive to layout; the communication antenna requires that the installation area is open and unobstructed.

The LED indicator light is controlled by the flight control and can display the current status. The light can emit red, blue, yellow, green, purple, and multiple colors, plus fast and slow flashing modes to indicate multiple states of the drone. For example, green slow flashing means that the self-check is normal and can take off, green fast flashing means that high-precision positioning can take off, red is an error, and yellow is to start fault protection.
