  25. UCT Processing Critical to SSA • Need to quickly restore order after fragmentation event – Iridium-Cosmos collision • Must reduce the number of unknown objects – Easier to spot new objects – Easier to regain custody of lost objects ~110k LEO Objects , ~20k Near GEO Objects in NASA 2030 Debris Catalog! Is it a known or unknown object? 25 DISTRIBUTION STATEMENT A – Unclassified, Unlimited Distribution

  26. Space Fence Radar Data • Problem has N 2 complexity 2 observations, but which two? – Must test all possible observation pairs ? ? ? ? UCTs are a difficult manual process: Resolving thousands of new objects can • ? ? take months Need for parallel processing • High capacity required (> 100,000 • observations) Full automation (catalog re-build) • Operational need drove R&D effort on UCT resolution 2 observations ( x y z v x v y v z ) 6 scalars 6 scalars 26 DISTRIBUTION STATEMENT A – Unclassified, Unlimited Distribution
