Systems Tool Kit & StellarXplorers

STK is a software tool that allows engineers and scientists to design and develop complex dynamic simulations of real-world problems, especially those relating to satellites, spacecraft, and aircraft. Through CAP's partnership with Analytical Graphics, the makers of STK, cadets are invited to test-fly this state-of-the-art technology.

STK is a fantastic aerospace/STEM activity for cadets, students, and adults!


DID YOU KNOW that the Air Force Association (AFA) has an exciting and challenging national competition that involves the use of STK?  StellarXplorers is a dynamic program and competition available to ANY high school team from schools, youth organizations, JROTC, OR CAP!  Competition leads up to a national competition held each spring in CO Springs.
