Plate.ActiveFace Property

Top

Description

Specifies which side of the Plate is active. The active side of the plate generates an SRP (solar radiation pressure) force when the Spacecraft's ForceModel is configured with ForceModel.SRP = 1 and ForceModel.SRPForceGeometry = 1. The inactive side of the plate is transparent to SRP, and therefore generates no SRP force.

The nominally active face is determined by the order that the vertices are specified: the right-hand rule is applied to the first three vertices to determine the direction of the normal vector for the plate. You can reverse the normal vector direction and change the active face for the plate by setting ActiveFace to 1, or by changing the order that the vertices are specified.
