"This Is A Test" (TIAT) is the Yellow Jacket Space Program's avionics and controls testbed launch vehicle designed for at least 4 test flights. Each flight will verify and validate YJSP's flight avionics and software systems, and its ability to model, test and control aerodynamics of launch environments. Tests will involve, in increasing difficulty, control in sub- and supersonic flight conditions, with roll, pitch, and yaw control through canards.

TIAT is built in three sections, a Controls section, a Recovery section, and a Booster section.

The Control section houses the Canard Can, a densely packaged actuator-linkage assembly with servos to control the canards themselves. It also houses all test-critical avionics, including the TIAT Flight Computer, flight software, flight sensors, external interfaces, cabling, and much more! 


The Recovery section houses twice redundant dual deploy altimeters of the drogue and main parachutes, each equipped with over 25 feet of shock cord, in addition to GPS tracking and camera feeds of launch and pyro separations.

The Booster is designed to be a modular NAR L2 section that propels our control payload to flight test conditions. It's designed to accept several different commercial motors with no rework required to fly again.
