Satellite Scenario Basics

You can build a complete satellite scenario simulation by using the Satellite Communications Toolbox functions and objects. The workflow for satellite scenario simulation consists of these five main components:

  • The satelliteScenario object represents a 3-D arena consisting of satellites, ground stations, and the interactions between them. Use this object to model satellite constellations, model ground station networks, perform access analysis between the satellites and ground stations, and visualize the results.

  • The satellite function adds satellites to the scenario using two line element (TLE) files or orbital elements. For more details on orbital elements and TLE files, see Two Line Element (TLE) Files.

  • The platform function adds platforms to the scenario using trajectory data or position or velocity data.

  • The groundStation function adds ground stations to the scenario using default parameters or the specified latitude and longitude.

  • The satelliteScenarioViewer function creates a 3D viewer for the scenario.

  • The play function simulates the satellite scenario and plays the results in the visualization window specified by satelliteScenarioViewer.

In the above architecture, you can replace the Satellite object with Platform (Satellite Communications Toolbox) object. In this case, the path (Satellite Communications Toolbox) object function replaces the orbit (Satellite Communications Toolbox) object function.

This diagram shows the architecture of satellite scenario simulation. Some of the object in the simulation share object functions.
