Mark I Video Payload System
This is my first attempt at creating a video system for a model rocket. The payload captures both video and audio of a launch through a Sony KX-131 color CCD camera and microphone and then transmits the data back to a receiving station positioned at the launch site. From there, video is recorded via a digital video recorder. The wireless link operates at 2.4GHz and the signal is FM modulated. Output power of the transmitter is approximately 500mW.
The rocket itself is a stock Aerotech HV Arcus. Simulations were performed in Rocksim to determine and maximize stability with the addition of the Video payload system. The mechanical models below were created with UGS Solid Edge V18.

At the left end of the unit is the transmitting planar antenna. It connects via a 50 ohm coaxial line to the 500mW transmitting amplifier. The KX-131 CCD color camera is secured using stand-offs and compressible foam. On the underside in blue is the Lithium battery, and not shown are the microphone, voltage regulation circuits, and safety key switch. The entire frame is made of Balsa wood and measures about six inches in length.
