Project History

CP6 development started when it was discovered that CP3 had low receive sensitivity issues. The backup flight unit of CP3 has since been modified with an LNA on the radio to increase uplink reliability, more robust software, and the addition of a secondary payload experiment built by NRL. The resulting satellite has been named CP6 and is now ready for launch.


The primary mission of CP6 is to implement an attitude control system using only magnetic torquers embedded within the side panels. Attitude determination is performed using two-axis magnetometers on each side panel as well as observation imagers on the payload face. Once the primary objectives have been met, a command will be sent to deploy the secondary payload that consists of a series of spring steel tapes. The data will be used to guide the future design of an electrodynamic tether.


CP6 has been launched. See NASA’s Tacsat-3 site for more information.
