Design and operate satellite systems with specialized propagators, attitude profiles, and satellite engineering tools.

STK's SatPro capability extends STK into the realm of high fidelity satellite systems modeling and analysis. The propagators included in SatPro can incorporate numerical integration and differential equations of motion, compute ephemeris for months and years, and integrate specialized propagation methods. SatPro also transforms attitude analysis for designers and operators with attitude spheres, attitude coverage, and tailored profiles and constraints. Finally, SatPro provides you with a collection of satellite engineering tools that model a satellite's surface area, mass, solar panel configuration, and more.
