Modeling a GNSS Satellite Constellation
Propagate a constellation of satellites in Simulink® using the Orbit Propagator block in Aerospace Blockset™ and load the logged ephemeris data into a satelliteScenario object for access analysis. The satelliteScenario object in Aerospace Toolbox lets you load previously generated, time-stamped ephemeris data into a scenario from a timeseries or timetable object. Data is interpolated in the scenario object to align with the scenario time steps, allowing you to incorporate data generated from a Simulink model into either a new or existing satellite scenario object. The satellite constellation can then be visualized using the Satellite Scenario Viewer. In the viewer, a line is drawn between each ground station and satellite during their corresponding access intervals.
