Module: THRSimConfig

struct THRSimConfig

#include <THRSimConfig.h>

Container for overall thruster configuration data for single thruster.

This structure is used to define the overall configuration of an entire thruster. It holds the current operational data for the thruster, the ramp/max/min configuration data, and the physical location/orientation data for a thruster.
