Geometry

Body frame vectors and surfaces are fundamental to building up a physical model of your satellite.

Body Frame Vectors

Body frame vectors are used to drive pointing modes, define the orientation of sensor boresights and comm antennas, and to describe exterior geometry. They are defined in the spacecraft body-frame by either a vector or polar coordinates.

Note: Take care when establishing your principal directions and origin. If you have a CAD model of your satellite, align your Sedaro Satellite body frame with the coordinate system in the CAD model - this will make extracting key vectors straightforward.

Surfaces

Surfaces are used as the mounting location for solar panels and will eventually be used to compute atmospheric drag, radiative heat transfer, and solar radiation pressure perturbations.
