TTA UAVs are Chinese UAV developed by Beijing (Northern) Tian-Tu (meaning Sky Way) Aviation Technology Development Co., Ltd. (TTA, 北方天途航空技术发展有限公司). Majority of the TTA products are unmanned helicopters, but there are also fixe-wing UAV as well. Most UAV developed by TTA utilizes commercial off-the-shelf (COTS) airframes integrated with flight control systems indigenously developed by TTA.
