Plan, design, build, and operate multi-faceted space missions.

One thing we all know — space systems are exceptionally complex and dynamic. To design and execute a successful mission, you need to integrate information and models from all domains and then simulate and analyze their performance in the variable conditions that can occur in space, on land, and everywhere in between. With so many complications in the mission environment, you need a software solution that's simple — a single platform to analyze and manage all your challenges.

Before the mission begins, you need to test designs early and often with digital prototypes. Reduce costs and accelerate your schedule by learning about problems that could be before they become problems that are.

After launch, you need to detect and diagnose anomalies quickly. The same analytical and visualization platform that supported your mission through planning and design extends to its operational phase. Maintain safe operations and maximize the return from your mission with accurate analytical modeling.

At AGI, we understand these needs and the stakes involved in meeting them. Ansys software can help you significantly streamline processes and mitigate risks throughout your system’s life cycle. From a single satellite to a large constellation, a simple orbit to a maneuvering trajectory, a basic signal relay to an EOIR sensor – when it comes to space, Ansys software has a long history of helping you plan your future.

Design trajectories

Use STK's Astrogator capability to design trajectories, including nominal maneuvers and station-keeping strategies.

Estimate orbits and update maneuver planning

Use ODTK to estimate orbits based on observations. You can use the updated orbit estimates in STK's Astrogator capability to re-plan station-keeping or other maneuvers.

Update planned maneuvers

Uplink maneuvers from STK's Astrogator capability to the spacecraft and use them in ODTK to prepare for the next orbit determination run.

Update mission planning data

Use your latest orbit solution from ODTK to update mission-planning products like ground-site acquisition times, eclipse predicts, payload access times to the areas of interest on the ground, and communication link margin analysis.

Fill in the gaps

Use STK Components to fill information gaps and generate data products that you can use in other software tools or operational status displays.
