When planning and conducting space missions, scientists and engineers must account for a wide
range of unique challenges in flight dynamics and system performance. STK can be used to model
accurate trajectories and orbits with full-flight dynamics with respect to mission requirements,
leveraging user-definable force models, coordinate systems and attitude definitions. Users can
also conduct trade studies and parametric analyses to optimize trajectories, plan maneuvers
and evaluate spacecraft engine design.
Along with its proven capabilities as a complex spacecraft trajectory and maneuver modeling solution,
the STK software suite promotes the quick and easy configuration of work environments for on-demand,
high-fidelity analyses of space missions around any planetary body. With mission planning tools to
simulate critical system performance and operational tools to evaluate real-time system performance,
AGI technology supports the mission from design, to launch, through mission end-of-life.
