Class DifferentialSignalBias

java.lang.Object

org.orekit.files.sinex.DifferentialSignalBias

public class DifferentialSignalBias
extends Object

Container for differential signal bias for a single link endpoint (either emitter or receiver).

This class is made to handle both station and satellite DSB data. Bias values are stored in TimeSpanMaps associated with a given pair of observation types. Those TimeSpanMaps are stored in a Map, which associate a pair of observation types to a TimeSpanMap of double values.

Method Detail

addBias

public void addBias(ObservationType obs1,
                    ObservationType obs2,
                    AbsoluteDate spanBegin,
                    AbsoluteDate spanEnd,
                    double biasValue)

Add a bias.

Parameters:

obs1 - first observation used for the DSB computation

obs2 - second observation used for the DSB computation

spanBegin - beginning of the validity span for this bias value

spanEnd - end of the validity span for this bias value

biasValue - DSB bias value (meters for code and cycle for phase)

getBias

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

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

Parameters:

obs1 - first observation type

obs2 - second observation type

date - date at which to obtain the DSB

Returns:

the value of the DSB (meters for code and cycle for phase)

getAvailableObservationPairs

public HashSet<Pair<ObservationType,ObservationType>> getAvailableObservationPairs()

Get all available observation type pairs for the satellite.

Returns:

observation type pairs obtained.

getMinimumValidDateForObservationPair

Get the minimum valid date for a given observation pair.

Parameters:

obs1 - first observation type

obs2 - second observation type

Returns:

minimum valid date for the observation pair

getMaximumValidDateForObservationPair

public AbsoluteDate getMaximumValidDateForObservationPair(ObservationType obs1,
                                                          ObservationType obs2)

Get the maximum valid date for a given observation pair.

Parameters:

obs1 - first observation type
