Below is the mission description from ULA's web site.

"Mission Description: AFSPC-6 (Air Force Space Command 6) will deliver two Geosynchronous Space Situational Awareness Program (GSSAP) satellites to near-geo­synchronous orbit. The twin GSSAP spacecraft, built by Orbital ATK, will support U.S. Strategic Command space enhanced awareness operations. Data from GSSAP will uniquely contribute to timely and accurate orbital predictions, enhancing our knowledge of the geosynchronous orbit environment, and further enabling space flight safety to include satellite collision avoidance."

According to, the GSSAP project was classified until 2014, and details about the satellites and their activities remain elusive.
