We provide cutting-edge satellite simulators to support the design, analysis, and optimization of NGSO & GSO satellite constellations – including LEO, MEO, and GEO systems.
As satellite networks become larger, more dynamic, and more complex, accurate system simulation and performance evaluation are more critical than ever.
Satellite simulation allows you to explore and test key parameters, conditions, and features before committing to costly hardware, satellite technologies, or deployment.
Explore satellite constellation features like Inter-Satellite Links, coverage, capacity, and resource allocation algorithms.
By simulating early in the planning phase, you reduce technical risk, avoid unnecessary costs, and make informed, data-driven decisions.
Identify and address communication bottlenecks and issues early, before physically building the system.
The number of satellites in orbit has more than doubled in the past five years. SatComs have increasingly shifted from Geostationary Orbit (GEO) to Non-Geostationary Orbit (NGSO) constellations, especially those in Low Earth Orbit (LEO).
LEO constellations offer lower latency and faster data transmission, enabling high-speed internet connectivity. However, global coverage requires deploying hundreds or even thousands of satellites.
Designing these constellations is a complex task, involving careful planning around gateway routing, Inter-Satellite Links, spectrum management, and performance optimization.
Simulation is a beneficial tool across all stages of constellation design. From the first stages of planning to post-launch refinement, it helps evaluate various design options, detect issues early, and ensure that the system meets evolving technical standards and user demands.
Our satellite constellation design service leverages the C-DReAM simulator, enabling precise modeling of satellite constellation performance.
C-DReAM is capable of modeling LEO, MEO and GEO satellite constellations of various sizes.
Evaluate satellite system capacity, optimize constellation parameters, analyze the coexistence of satellite and terrestrial systems – and more.
C-DReAM is highly configurable, with support for customer and project specific modifications.
In the NTN-CPD project, we’re designing and validating 5G NR control plane procedures for NTN using the Nova satellite simulator. Nova enables detailed evaluation of dynamic NGSO constellations, supporting both standardization and industrial applications.
By simulating features like Inter-Satellite Links, mobility management, and UE measurements, Nova helps uncover optimization opportunities and implementation challenges for future 5G-compliant satellite networks.
This growth of LEO satellite constellations is reshaping the future of SatCom by enabling global, low-latency connectivity. However, this also demands advanced system design.
At Magister, we are always on the lookout for new and better uses of technology for optimizing NGSO constellations.

What are LEO, MEO, and GEO satellites / satellite constellations?
Low Earth orbit (LEO) satellites orbit the Earth at an altitude between approximately 160 and 2000 km. They are typically used for purposes such as providing low latency internet connection around the world, and Earth observation.
Medium Earth orbit (MEO) satellites typically operate between 2000 to 35,786 km above the Earth’s surface. They are commonly utilized for GPS and navigation purposes, as well as communication.
Geostationary (GEO) satellites are located precisely at 35,786 km above the Earth. This unique position allows them to remain in a fixed position relative to the Earth’s surface. Therefore they’re able to continuously communicate with the same geographic area. GEO satellites are used for different applications, including telecommunications, broadcasting, and navigation.
What are the benefits of satellite networks?
Satellites and satellite networks provide key benefits such as global internet access, GPS navigation, TV and radio broadcasting, surveillance, and environmental monitoring.
They also contribute to scientific research and play a vital role in public safety and disaster management by enabling rapid information sharing.
For example, during natural disasters – when terrestrial networks may be damaged – satellite networks can continue to operate and provide critical communication.
What is satellite internet?
Satellite internet means internet access delivered via communication satellites, using signals transmitted between satellites in orbit and ground stations on Earth.
This enhances global connectivity by extending internet access to rural, remote and hard-to-reach areas.
What is the role of satellites in 5G?
Satellites play a complementary role in 5G by bridging coverage gaps of terrestrial networks. They extend connectivity to remote, rural and hard-to-reach areas, where traditional terrestrial networks are unavailable.
