Graphical simulator in MATLAB® that aims to assist in the design of a multibeam satellite communications system to provide broadband fixed-satellite service in Europe.
mfs3 can generate relevant graphical presentations of system parameters on a map of a defined geographical region of interest.

| Frequency/polarization reuse plan. | Attenuation due to rainfall in Ka band. |
Different maps related to the architecture and frequency plan of the communications system can be produced, including the following:
- Coverage region and user beam center locations.
- Gateway ground station locations.
- Allocation of user beams to gateway stations.
- Frequency/polarization reuse plan across user beams.
The simulator can also perform link budget calculations on a large coordinate grid. Maps can be generated for different magnitudes involved in the budget, such as:
- Attenuation (due to free-space path loss, rainfall, clouds/fog and atmospheric gases).
- Co-channel interference levels in user beams.
- Carrier to noise (C/N), interference (C/I) and intermodulation (C/IM) ratios.
Some example scripts are provided that demonstrate the different functions supported by the simulator.
This software was developed as part of a course in Satellite Communications at the Polytechnic University of Madrid, for a project titled “Design of a multibeam satellite for Europe (FSS): Comparison of performance with Ka vs Q/V feeder links”.
The objective was to compare the impact of using Ka band or Q/V band feeder links in the throughput, transponder achitecture and ground segment of a multibeam fixed-satellite service. A graphical simulator was to be developed to assist in the preliminary design of the system in both scenarios.
