Astrodynamics Support Workstation (ASW)

The Astrodynamics Support Workstation (ASW), first adopted as an operational system in 1998, was the first mission system to produce full Special Perturbation (SP) Satellite Catalog and provide full SP Conjunction Assessment (CA) screenings. It is tuned to the unique Space Surveillance Network (SSN) data attributes and Air Force Space Command (AFSPC) mission requirements. Its state-of-the-art functionality has expanded and algorithms have continually improved based on operational experience, studies, and innovation. The new capabilities have been developed under AFSPC sponsored Space Situational Awareness (SSA) initiatives and have been numerically validated by AFSPC at each stage of development and reviewed operationally by the JSpOC and various user agencies (NRO, 50th Space Wing, and NASA).

ASW is the primary operational ground system in the JSpOC providing:

  • First and only AF certified Special Perturbations (SP) space catalog
  • Unique satellite drag modeling
  • Satellite Maneuver Processing
  • Sensor Tasking
  • SP Observation Association
  • Conjunction Assessment (on-orbit, launch, hyperbolic fly-bys)
  • Performance Metrics
  • Ephemerides Generation
  • Reentry assessment support (used for Phobos-Grunt and Brunt Frost)
  • Sensor Calibration
  • AF compliant Training
