Constructor Details

AltitudeEventFunction

public AltitudeEventFunction(BodyShape body,
 double criticalAltitude)

Constructor.

Parameters:

body - body

criticalAltitude - altitude for crossing

Method Details

value

public double value(SpacecraftState state)

Description copied from interface: EventFunction

Evaluate function.

Parameters:

state - spacecraft state

Returns:

value

value

public <T extends CalculusFieldElement<T>> T value(FieldSpacecraftState<T> fieldState)

Description copied from interface: EventFunction

Evaluate Field function. By default, calls the non-Field version. This is suitable for detection but not be for applications like automatic differentiation, where a proper implementation should be used instead.

Type Parameters:

T - field type

Parameters:

fieldState - spacecraft state

Returns:

value
