 COFM video transmitter


ST6200BM is a cost-effective COFDM wireless transmission equipment specially designed for UAV(unmanned aerial vehicle) applications. It supports HD 720P(1280*720). Using COFDM modulation technology, frequency bandwidth is 6MHz with a very strong anti-multipath interference ability. Compare with traditional analog and modulation technology, this model is more suitable for complex environment. It own diffraction and mobile function by using low frequency. It can transmit HD HDMI video in high speed movement. Mini size, weight 120g, transmit power 400mw, it is easy to carry and often used in short distance on ground and long distance transmission from air to ground. As special transmission: used for image collection including light UAV machine, super light UAV machine, spin wing UAV, mini UAV, unmanned boat, unmanned car, airship, drone aircraft, USV and all driving device. On ground LOS distance: 1-2km, air to ground 1-5km.

4. Application Introduction

Mainly transfer way: UAV~Car control station~ Control center~Internet to different city control center.
UAV assemble mini devices, transfer air live video signal to the communications station, or a local command centre. Local display monitor, storage command center can direct send the audio and video to real-time monitoring, dispatch. Other video way directly through the metropolitan area network or Wan transfers to the provinces and command center; to access PC browsing management, videos and so on.
