Trait nyx_space::dynamics::thrustctrl::ThrustControl

pub trait ThrustControl: Send + Sync {
    fn direction(&self, state: &SpacecraftState) -> Vector3<f64>;
    fn throttle(&self, state: &SpacecraftState) -> f64;
    fn next(&self, state: &SpacecraftState) -> GuidanceMode;

    fn achieved(&self, _state: &SpacecraftState) -> Result<bool, NyxError> { ... }
}

The ThrustControl trait handles control laws, optimizations, and other such methods for controlling the overall thrust direction when tied to a Spacecraft. For delta V control, tie the DeltaVctrl to a MissionArc.

Required methods

fn direction(&self, state: &SpacecraftState) -> Vector3<f64>

Returns a unit vector corresponding to the thrust direction in the inertial frame.

fn throttle(&self, state: &SpacecraftState) -> f64

Returns a number between [0;1] corresponding to the engine throttle level. For example, 0 means coasting, i.e. no thrusting, and 1 means maximum thrusting.

fn next(&self, state: &SpacecraftState) -> GuidanceMode

Prepares the controller for the next maneuver by returning the next guidance mode.
