. Cameras on the satellite will be used to verify the data returned by the attitude sensors.
Satellite
Originally built as a backup to
CP3 CubeSat, while CP3 is considered an operational satellite by the PolySat team, unreliable radio issues have prevented full operation of the spacecraft's mission-required sensors. which was launched on 17 April 2007,
CP6 was modified after it was decided that it would no longer be needed for that role.
In addition to the attitude determination experiment, CP6 also planned to test a system to collect

Mission
Electrodynamic propulsion offers the prospects of enabling spacecraft to maneuver without the expenditure of conventional fuel, that is the possibility of propellant-less maneuvers. This experiment consists of three deployable devices, an electron emitter consisting of two thoriated

filaments which reside at the end of a rolled up steal tape and two electron collectors that are rolled up steel tapes, each long. The tapes and electronics of the experiment are housed in a high space on one side of a deployable door nestled around two cameras of the Cal Poly primary mission. The deployable door and rolled up tapes will be deployed at the conclusion of the Cal Poly primary mission and last for 3–6 months. The mission data will be downlinked to ground stations at the Naval Research Laboratory and Cal Poly.
