These products are built for any mission in any phase of the life-cycle. From concept through operations, our space tools can help with system architecture, trajectory design, orbit determination, subsystem analysis and much more. These tools have been used by thousands of engineers and operators on hundreds of successful satellite programs. Fly your satellites with the same software used to design and test them.

Systems Tool Kit (STK)

STK provides an inclusive modeling environment used worldwide by public and private sector organizations to model complex land, sea, air, or space systems and evaluate their performance in real or simulated time. STK supports timely decision-making in a mission context about complex, inter-related systems; and can be applied at any stage in their lifecycle: from planning and design to training and operations.
