Satellite Communications Toolbox


Satellite Communications Toolbox

Simulate, analyze, and test satellite communications systems and links

Orbit Propagation and Visualization

Model satellites with two-body, SGP4, or SDP4 orbit propagators. Visualize 2D and 3D satellite orbits including field of view, ground tracks, and sky plots for navigation. Generate satellite constellations from TLE files or ephemeris data.

Access and Link Analysis

Analyze line-of-sight access. Compute link closures from satellites to ground stations or between satellites. Simulate multihop communications links between ground stations.

Link Budget Analysis

Configure, analyze, and visualize link budgets for satellite communications. Analyze availability with the ITU P.618 propagation loss model. Analyze sensitivity with custom line and contour visualizations.

Waveform Generation

Generate standard-based waveforms for satellite communications (DVB-S2/S2X/RCS2 and CCSDS TC/TM) and navigation (GPS). Use waveforms as golden references for your design.

Channel Modeling

Use the ITU-R P.618 propagation loss model to design Earth-space links. Analyze space-based 5G links with the 5G non-terrestrial network (NTN) channel. Configure a deep space optical link with a Poisson channel.

Link-Level Simulation

Simulate satellite communications links using DVB-S2/S2X/RCS2, GPS, and CCSDS waveforms. Use receivers built with open MATLAB code to perform all synchronization operations. Analyze link performance by computing bit error rate (BER) and packet error rate (PER) metrics.
