DAVE is a 1U CubeSat spacecraft, measuring approximately 10x10x11cm. The spacecraft was integrated into a PPOD (Poly
Picosatellite Orbital Deployer) alongside the University of Central Florida's SurfSat. Fixed solar panels on the sides of the spacecraft provide power to the avionics and transmitter.

As the satellite's experiment is contained entirely within the spacecraft and does not require any external influence (other than the existence of the low-Earth orbit environment), DAVE contains no attitude control system. A deployable UHF dipole antenna was used to provide fairly omnidirectional

element over a range of frequencies. The data from the vibration payload can be used to potentially develop systems to dampen out harmful vibrations on future spacecraft. Payload data is downlinked from the spacecraft and processed on the ground.
