Spacecraft

Model, simulate, and visualize the motion and dynamics of spacecraft

Use the spacecraft blocks, available in the Aerospace Blockset > Spacecraft sublibrary, to model, simulate, and visualize the dynamics of spacecraft.

Blocks

Attitude Dynamics	Model attitude dynamics of one or more spacecraft (Since R2023a)
Attitude Profile	Calculate shortest quaternion rotation (Since R2020b)
CubeSat Vehicle	Model CubeSat vehicle (Since R2019a)
Eclipse Shadow Model	Calculate fraction of solar disk visible at inertial positions (Since R2023b)
Orbit Propagator	Propagate orbit of one or more spacecraft (Since R2020b)
Spacecraft Dynamics	Model dynamics of one or more spacecraft (Since R2021b)

Lunar Mission Analysis with the Orbit Propagator Block

Compute and visualize access intervals between the Apollo Command and Service module and a rover on the lunar surface. The module's orbit is modeled using Reference Trajectory #2 from the NASA report Variations of the Lunar Orbital Parameters of the Apollo CSM-Module [2]. This is a lunar orbit studied by NASA for the Apollo program. The example uses:
