AGI STK is a physics-based software package that allows engineers and scientists to perform complex analyses of ground, sea, air, and space assets, and share results in one integrated solution. At the core of STK is a geometry engine for determining the time-dynamic position and attitude of assets, and the spatial relationships among the objects under consideration including their relationships or accesses given a number of complex, simultaneous constraining conditions. STK has been developed since 1989 as a commercial off the shelf software tool. Originally created to solve problems involving Earth-orbiting satellites, it is now used in both the aerospace and defense communities for many other applications. AGI states that STK has more than 40,000 installations at more than 800 global organizations such as NASA, ESA, CNES, DLR, Boeing, JAXA, ISRO, Lockheed Martin, Northrop Grumman, EADS, DOD, and Civil Air Patrol.
