On detecting and early-warning function simulation of STSS based on STK

Space Tracking and Surveillance System is the American new developing early-warning satellite system, which would have more perfect function compared with traditional ones. Based on the theories of detecting and early-warning, established some detecting and early-warning models, including location models, launch point, burnout point and fall point parameter forecast models. Moreover, the paper simulated the function of STSS based on STK, as a basement for the further research.
