Satellite Mission Analysis

Model and visualize satellite scenarios using a satelliteScenario object; use functions to support Aerospace Blockset™ spacecraft

Generate satellite scenarios to model and visualize satellites in orbit and perform additional analyses, such as computing access with ground stations. You can directly call satelliteScenario and satellliteScenarioViewer objects. To create objects for other classes, use their object creation functions (for example, satellite for a Satellite object and groundStation for a GroundStation object).
