Launch Notes: AFSPC-4 will be the 33rd ULA mission for the U.S. Air Force. It will be the eighth of 15 planned missions ULA is slated to launch in 2014, and ULA’s 85th since the company formed in 2006.

Mission Description: The AFSPC-4 mission will deliver two Geosynchronous Space Situational Awareness Program (GSSAP) satellites to near-geosyn¬chronous orbit and will also carry an Automated Navigation and Guidance Experiment for Local Space (ANGELS) satellite.

The twin GSSAP spacecraft will support U.S. Strategic Command space surveillance operations as a dedicated Space Surveillance Network (SSN) sensor. The GSSAP will also support Joint Functional Component Command for Space (JFCC SPACE) tasking to collect space situational awareness data, allowing for more accurate tracking and characterization of man-made orbiting objects.

The ANGELS satellite is managed by the Air Force Research Laboratory (AFRL) Space Vehicles Directorate. As part of AFRL’s research in advanced Space Situational Awareness (SSA), ANGELS examines techniques for providing a clearer picture of the environment surrounding our nation’s vital space assets.
