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 situ¬ational 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.
Cubicle Warrior’s Note: AFSPC-4 will launch to the east at 1900 EDT to super-GEO and do a seven-hour circularization maneuver before final separation of secondary payloads at near-GEO over optimum conditions for lighting, as well as command and control.
