STK 12.2 introduces the Satellite Collection object — available in preview — for modeling large constellations. You can use a satellite collection to represent an entire constellation of satellites (we’ve tested 450,000!) as a single object in STK to provide basic visualization, a minimal memory footprint, and efficient save and load operations. You can use the object to analyze:

  • Sensor coverage
  • Visibility intervals
  • Orbital conjunctions
  • Communications interference

If you're an STK 12.2 user, you can request a 30-day preview license today. Once your preview has concluded, we'll send you a short survey about your experience. Your feedback will help us improve this new feature.
