public FieldLatitudeCrossingDetector(Field<T> field, OneAxisEllipsoid body, double latitude)
The new instance uses default values for maximal checking interval
(FieldAbstractDetector.DEFAULT_MAXCHECK
) and convergence threshold (FieldAbstractDetector.DEFAULT_THRESHOLD
).

public T g(FieldSpacecraftState<T> s)
The value is the spacecraft latitude minus the fixed latitude to be crossed. It is positive if the spacecraft is northward and negative if it is southward with respect to the fixed latitude.
