A basic FPV system transmits videos from small CCD or CMOS cameras wirelessly to the display device on the ground. On the aircraft, the primary components are a camera, video transmitter, and custom antenna. On the ground, the video is received by an antenna hooked to a video receiver, which is either part of video glasses or feeds the video to a monitor. The video feed allows the “pilot” to see where they are flying while they use an RC transmitter to control the aircraft. Often flight controllers are used on the aircraft to offer everything from basic flight control and stabilization, all the way to fully autonomous flight.
