Systems Tool Kit (formerly Satellite Tool Kit), often referred to by its initials STK, is a physics-based software package from Analytical Graphics, Inc. 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. |
