C-DReAM

laptop with satellite constellation simulation

Simulator for satellite constellation design

C-DReAM is a Python implemented simulator with the capability to simulate various sized NGSO and GSO satellite constellations. It’s a link budget / capacity level simulator that operates on a configurable time resolution.

With C-DReAM, you can 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.

- Evaluate 5G NR-NTN usability for NGSO satellite constellation systems.
Perform coverage and geospatial analysis
- E.g. hyperspectral camera and SAR satellite constellations
- Thermal, radiation and energy analyses assisted with orbit simulations
- Calculate spatial relationships between non-terrestrial and terrestrial objects
Analyze interference and coexistence
- E.g. between satellite systems or between satellite and terrestrial systems

Comparing DVB-S2X/RCS2 and 5G NR-NTN

Forsway: Comparison project of DVB-S2X/RCS2 and 5G NR-NTN technologies

Magister executed a DVB-S2X/RCS2 and 5G NR-NTN comparison project for Forsway in a geostationary satellite broadband scenario.

During the project, we conducted theoretical comparisons and utilized C-DReAM for link level evaluations and capacity-level system simulations.

The project provided Forsway with valuable insights into the performance differences of 5G NR and traditional DVB for SatCom.

Researching 5G-Advanced and 6G NTN technologies

EAGER: Researching future 5G-Advanced and 6G NTN technologies

The ESA-funded EAGER project explored future 5G-Advanced and 6G NTN technologies to pave the way for new use cases and support 3GPP standardization.

Magister led the simulative analysis, enhancing the C-DReAM and ALIX simulators to evaluate future NTN technologies.

“We researched various potential technologies in this project and tested them through simulations. These techniques may very well be the basis for future 5G-Advanced and 6G standards.”

Exploring SatCom systems for UAV terminals

UAV-3S: Exploring possibilities of using SatCom systems for UAV terminals

The objective of the UAV-3S project is to develop and test an end-to-end system simulator that provides performance indicators for the development of UAV satellite terminals.

Magister is using the C-DReAM simulator as a baseline for UAV-3S, further enhancing it towards the UAV SatCom use case.

The simulator will implement UAV logistics use cases, such as realistic UAV path and attitude traces and channel models.
