TSC supports the National Missile Defense (NMD) program in the Verification Validation and Accreditation (VV&A) and Independent Verification and Validation (IV&V) activities related to NMD models and simulations.

As part of these efforts, TSC developed and is using a number of tools for analyzing NMD simulation results. One of these tools, the NMD Probability Analysis Tool (NPAT), employs probabilistic performance models of the various NMD elements. It is intended to permit rapid sanity checks on the outputs of the detailed “high fidelity” NMD simulations. Because it is very fast, this tool can also be an aid in planning scenarios for these simulations. This is important, because the latter simulations are inherently computationally intensive and, therefore, relatively slow. Developing the NPAT tool was greatly simplified TSC’s Simulation Framework (SF) software.

Among other things, the SF software includes coordinate conversion routines and graphical support, which make it easy to generate and visualize target trajectories in a world view context.
