Project History

Project development began in 2007, and has been through several revisions and worked on by various teams. The final team completed development in December 2011 to prepare for integration on the ELaNa-6 mission. The program was extended well-beyond its desired completion date, as with most projects. However, the team envisions a successful sail deployment and de-orbit of the spacecraft after deployment from NROL-36.

Operations and Tracking

CP5 is ground-operated with a software TNC known as MixW (more information can be found at the “Earth Station” link at the top of the page), and Yaesu FT-847 and ICOM IC-910 radios. Additionally, a Python-based decoder is used as the primary operations application on the ground station, which is GUI based and can support data acquisition from multiple ground stations. If you’re interested in helping to track and acquire data from CP5, more information can be found on our MoreDBs page.


Current TLE for CP5 is available here.
