Constructor Detail

MinimumElevationEventFunction

public MinimumElevationEventFunction(AtmosphericRefractionModel refractionModel,
                                     TopocentricFrame topo,
                                     double minimumElevation)

Constructor.

Parameters:

refractionModel - reference to refraction model (can be null in which case no correction is applied)

topo - reference to a topocentric model

minimumElevation - min. elevation defining function's root

Method Detail

getMinimumElevation

public double getMinimumElevation()

Getter for the minimum elevation.

Returns:

min. elevation

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
