    What Is Satellite Communications Toolbox?

    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, 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.

    Satellite Communications Toolbox enables you to simulate, analyze, and test satellite communications systems and links. With the toolbox, generate, propagate, and visualize satellite orbits with a variety of propagators. Generate 2D and 3D orbit animations that show ground tracks and fields of view. Perform dynamic visibility analyzes on satellites and ground stations. Perform dynamic communications link analyzes on those same assets.

    Model satellites, aircraft, and other mobile platforms in the same scenario. Create and visualize antenna patterns from single antennas or electronically steered arrays. Use an app to analyze satellite link budgets for up, down, and cross-links. Include an annualized availability analysis based on the ITU P.618 recommendation. Generate Matlab code from the app to get started on parametric trade studies for your link budgets.

    Analyze an optical link budget while accounting for atmospheric absorption and scattering. Use an app to generate waveforms based on satellite standards, like DVB-S2, S2X, or RCS2. Generate legacy GPS waveforms with C/A and P spreading codes and modernized L1C waveforms. Also generate L5, S, and L1 NaviC waveforms. Model losses due to gas, clouds, rain, and tropospheric scintillation, based on the ITU P.618 recommendation.

    Model an optical Poisson channel, useful for pulse position modulated systems. Model a 5G non-terrestrial or NTN channel. This includes a narrowband frequency flat channel and a tapped delay line frequency selective channel. Simulate point-to-point links for systems like DVB-S2, S2X and RCS2 and CCSDS telecommand and telemetry. Create and correct for impairments, like phase noise, carrier frequency offsets, and symbol timing offsets.

    Perform a 5G NTN downlink simulation that includes the effect of satellite motion, inducing time varying Doppler and delay. Model power amplifiers with and without memory. Calculate throughput as a percentage of packets that are received error free.
