Your Partner in Orbital Engineering and Space Simulation
Driving Innovation Across Launch, Satellite & Deep-Space Vehicles
Getting hardware to orbit (and keeping it there) means mastering extreme temperatures, vacuum, radiation, and dynamic loads that no terrestrial product ever sees. Ansys’ digital engineering platform unifies propulsion CFD, structural and thermal FEA, guidance & control analysis, antenna/RF modelling, and real-time mission simulation so your teams can design, verify, and operate confidently from concept to constellation.
Space Systems Engineering Challenges
- Launch and Vibration Loads
Extreme acoustic and vibrational forces during launch can damage sensitive spacecraft systems. Multiphysics simulation predicts structural response, modal behavior, and fatigue risk to ensure survivability from liftoff through orbital deployment. - Orbital Thermal Extremes
Spacecraft experience rapid transitions between intense solar heating and deep cold in eclipse. Simulation models thermal gradients and heat transfer to protect electronics, maintain stability, and ensure reliable performance in orbit.
- RF and Antenna Performance in Vacuum
Spacecraft antennas must operate reliably despite thermal distortion and structural deformation. Electromagnetic simulation predicts radiation patterns, coupling, and signal integrity to ensure dependable communications throughout the mission. - Space Environment Material Stress
Vacuum conditions, radiation exposure, thermal cycling, and mechanical loads affect the durability of spacecraft, habitats, suits, and mission-critical materials. Predict deformation, thermal expansion, and long-term structural behavior to ensure reliability across all space-exposed systems with the help of multiphysics simulation.
