Understand System Behavior Before Deployment

The space landscape is evolving, and growing more complex by the day.

With thousands of satellites already in orbit and tens of thousands more on the way, optimizing these intricate systems is more critical than ever.

At the same time, the rise of non-terrestrial networks – including 5G and 6G NTN – is reshaping global connectivity. Satellite networks are integrating with terrestrial ones, bridging coverage gaps and extending connectivity to new, underserved regions.

This growing complexity requires deep understanding of these systems, their coexistence, and behaviour – before and after deployment.

Why Is Simulation Essential for Space System Design?

System-level simulation means creating digital models of real-world systems to understand and predict their behavior, performance, and interactions. It’s a powerful tool for optimizing complex systems before building them physically.

Simulation also helps refine the system once it’s operational. Real-world data of the system can improve accuracy, as evolving use cases, user needs, or gateway locations can require adjustments – including the need for additional satellites.

In the space sector, simulation is especially valuable because of:

  • System complexity – Involving the space environment, spacecraft, ground systems, and support systems
  • High risks – Including technical, operational and environmental uncertainties
  • Significant costs – From design and manufacturing to launch and potential technical challenges/failures
  • Long development cycles – Requiring early validation to avoid costly redesigns later

Explore Solutions Cost-Effectively

Accelerate tech development & innovation


Simulation is faster and simpler than physical field tests, allowing rapid testing of multiple scenarios, parameters, conditions, and systems.

Innovate and develop new features more quickly.

Optimize performance


Simulation gives deep insights into system behavior, letting you optimize performance in controlled environments before and after deployment.

Cut development costs


Test in realistic conditions without the high costs of real-world trials.

Reduce costs in the planning phase of the mission – before investing in e.g. satellite technologies.

Test limitlessly


Run countless simulations across different circumstances to identify issues early.

Explore and test a wide range of potential solutions.

From Concept to Orbit

Support before and after launch

The value of simulation doesn’t end with the first launch. You can optimize your system before deployment  – and continue refining it as it operates in the real world.

After launch, our system simulation software helps you:

  • Explore the need for additional satellites
  • Adjust the system to evolving industry standards. Our software is regularly updated with new standards, improved algorithms, new bandwidth specifications, etc.
  • Adapt the system to changing use cases, user needs, terminals, and gateway locations & numbers
  • Refine the system using real-world data
  • Model real-world problems to deepen understanding of the system

With Simulation

Without Simulation

Run an unlimited amount of tests virtually  – faster and cheaper.

Detect and resolve issues early before committing to expensive hardware.

Simulate and iterate faster. Explore freely with new technologies and features, like hybrid networks or beam hopping.

Test complex scenarios with different parameters, conditions and circumstances to observe system behavior.

Physical testing can be expensive, time-consuming, and limited.

Issues and bottlenecks may be discovered too late, when they’re expensive to fix.

Development cycles are long and costly.

 Complex space scenarios are difficult to recreate in real-world settings, such as satellite network behavior and performance.
