Uav image transmission equipment is a core component of UAV and its main function is to use appropriate video compression technology, signal processing technology, channel coding technology and modulation and demodulation technology, the video captured by the camera mounted on the scene UAV to wireless real-time transmission of a wireless electronic transmission equipment behind the distance. It is divided into two parts: transmitting and receiving.

At present, the system and resolution of full HD image transmission on the market are mainly 1080i and 1080p. Its commonly used frame rate can be divided into 25fps, 30fps, 50fps and 60fps four kinds, bandwidth is basically divided into 4MHz, 6MHz and 8MHz three kinds, the actual stream speed is from 2Mbps to 12Mbps, end-to-end transmission delay is basically between 400ms to 1200ms, 1W transmission power effective transmission Distances range from a few hundred meters to around 20km.
