Assembly

NominalSystems.Messages.dll

[Nominal] Message describing the current state of a spacecraft. This can define all parameters on the spacecraft at a point in time, relative to the body or inertial frame. The body frame (B) is the spacecraft's frame and the center of mass frame (C) is the center of mass of the spacecraft, including all components.
