FieldEventDetector<T>
public class FieldCylindricalShadowEclipseDetector<T extends CalculusFieldElement<T>> extends FieldAbstractDetector<FieldCylindricalShadowEclipseDetector<T>,T>
Event detector for eclipses from a single, infinitely-distant light source, occulted by a spherical central body. The shadow region is cylindrical, a model less accurate than a conical one but more computationally-performant.The so-called g function is negative in eclipse, positive otherwise.

getOccultingBodyRadius
public T getOccultingBodyRadius()
Getter for occulting body radius.- Returns:
- radius
-
g
public T g(FieldSpacecraftState<T> s)
Compute the value of the switching function. This function must be continuous (at least in its roots neighborhood), as the integrator will need to find its roots to locate the events.- Specified by:
g
in interfaceFieldEventDetector<T extends CalculusFieldElement<T>>
- Specified by:
g
in classFieldAbstractDetector<FieldCylindricalShadowEclipseDetector<T extends CalculusFieldElement<T>>,T extends CalculusFieldElement<T>>
- Parameters:
s
- the current state information: date, kinematics, attitude- Returns:
- value of the switching function
-
create
protected FieldCylindricalShadowEclipseDetector<T> create(FieldAdaptableInterval<T> newMaxCheck, T newThreshold, int newMaxIter, FieldEventHandler<T> newHandler)
Build a new instance.- Specified by:
create
in classFieldAbstractDetector<FieldCylindricalShadowEclipseDetector<T extends CalculusFieldElement<T>>,T extends CalculusFieldElement<T>>
- Parameters:
newMaxCheck
- maximum checking intervalnewThreshold
- convergence threshold (s)newMaxIter
- maximum number of iterations in the event time searchnewHandler
- event handler to call at event occurrences- Returns:
- a new instance of the appropriate sub-type
