Class Dcb

java.lang.Object

org.orekit.files.sinex.Dcb

public class Dcb
extends Object

Class to store DCB Solution data parsed in the SinexLoader.

This class is made to handle both station and satellite DCB data. Bias values are stored in TimeSpanMaps associated with a given pair of observation codes. Those TimeSpanMaps are stored in a Map, which associate a pair of observation code (as a HashSet of ObservationType) to a TimeSpanMap, encapsulated in a DCBCode object.

Method Detail

addDcbLine

public void addDcbLine(String obs1,
                       String obs2,
                       AbsoluteDate spanBegin,
                       AbsoluteDate spanEnd,
                       double biasValue)

Add the content of a DCB line to the DCBSatellite object.

The method check the presence of a Code pair in a map, and add values to the corresponding TimeSpanMap.

Parameters:

obs1 - String corresponding to the first code used for the DCB computation

obs2 - String corresponding to the second code used for the DCB computation

spanBegin - Absolute Date corresponding to the beginning of the validity span for this bias value

spanEnd - Absolute Date corresponding to the end of the validity span for this bias value

biasValue - DCB bias value expressed in S.I. units

getDcb

public double getDcb(String obs1,
                     String obs2,
                     AbsoluteDate date)

Get the value of the Differential Code Bias for a given observation pair and a at a given date.

Parameters:

obs1 - string corresponding to the first code used for the DCB computation

obs2 - string corresponding to the second code used for the DCB computation

date - date at which to obtain the DCB

Returns:

the value of the DCB in S.I. units

getDcb

public double getDcb(ObservationType obs1,
                     ObservationType obs2,
                     AbsoluteDate date)

Get the value of the Differential Code Bias for a given observation pair and a at a given date.

Parameters:

obs1 - first observation type

obs2 - second observation type

date - date at which to obtain the DCB

Returns:

the value of the DCB in S.I. units

getAvailableObservationPairs

public HashSet<org.hipparchus.util.Pair<ObservationType,ObservationType>> getAvailableObservationPairs()
