Constructor Detail

AbstractDetectorWithTropoCorrection

protected AbstractDetectorWithTropoCorrection(GeometricStationAntenna stationModel,
                                              AngularCorrection correctionModel,
                                              double maxCheck,
                                              double threshold)

Constructor for the abstract event detector using a station elevation correction.

The maximal interval between elevation checks should be smaller than the half duration of the minimal pass to handle, otherwise some short passes could be missed.

Parameters:

stationModel - the geometric model of the ground station antenna

correctionModel - the angular correction model (set null to ignore the station elevation correction)

maxCheck - maximal checking interval (s)

threshold - convergence threshold (s)

Method Detail

getCorrectedVector

protected Vector3D getCorrectedVector(SpacecraftState s)
                               throws OrekitException

Compute the apparent vector from the station to the spacecraft with tropospheric effects.

Parameters:

s - the current state information: date, kinematics, attitude

Returns:

the apparent vector from the station to the spacecraft with tropospheric effects

Throws:

OrekitException - if some specific error occurs

getStation

public GeometricStationAntenna getStation()

Get the station.

Returns:

the station antenna geometric model

getCorrection

public AngularCorrection getCorrection()

Get the correction.

Returns:

the correction
