CustomVisibilityFromStationDetector

public CustomVisibilityFromStationDetector(org.orekit.bodies.GeodeticPoint stationCoordinates,
                                           org.orekit.bodies.ExtendedOneAxisEllipsoid earthShape,
                                           int visibilityDetectorChoice,
                                           int triggerCount)
                                    throws org.orekit.errors.OrekitException

Constructor with reduced data. maxCheck (600 s), threshold (1.0e-6 s) and action (RESET_STATE) by default.

Parameters:

stationCoordinates - antenna station geodetic coordinates

earthShape - Earth body shape (ellipsoid)

visibilityDetectorChoice - 0-entering FoW, 1-exiting FoW, 2-entering or exiting FoW

triggerCount - for successive event ocurrences, count for which the event must be triggered.

Throws:

org.orekit.errors.OrekitException - error when loading the ephemeris files
