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 bysatelliteScenarioViewer
.
This diagram shows the architecture of satellite scenario simulation. Some of the object in the simulation share object functions.
The
Satellite
,GroundStation
, andConicalSensor
objects share theaccess
object function.The
Satellite
,GroundStation
,GroundTrack
, andAccess
objects share theshow
andhide
object functions.The
Satellite
,GroundStation
, andGimbal
objects share theconicalSensor
object function.The
Satellite
andGroundStation
objects share thetransmitter
andreceiver
object functions.The
Transmitter
andReceiver
objects share thelink
object function.
In the above architecture, you can replace the Satellite
object with Platform
object. In this case, the path
object function replaces the orbit
object function.
