Satellite Communications Toolbox provides standards-based tools for designing, simulating, and verifying satellite communications systems and links. The toolbox enables you to model and visualize satellite orbits and perform link analysis and access calculations. You can also design physical layer algorithms together with RF components and ground station receivers, generate test waveforms, and perform golden reference design verification.
With the toolbox you can configure, simulate, measure, and analyze end-to-end satellite communications links. You can also create and reuse tests to verify that your designs, prototypes, and implementations comply with satellite communications and navigations standards, DVB-S2X, DVB-S2, CCSDS, and GPS.
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.
