Class ObservableSpecificSignalBias

java.lang.Object

org.orekit.files.sinex.ObservableSpecificSignalBias

public class ObservableSpecificSignalBias
extends Object

Container for observation-specific signal bias for a single link endpoint (either emitter or receiver).

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

13.0

Method Detail

addBias

public void addBias(String obs,
                    AbsoluteDate spanBegin,
                    AbsoluteDate spanEnd,
                    double biasValue)

Add a bias.

Parameters:

obs - observation used for the OSB computation

spanBegin - beginning of the validity span for this bias value

spanEnd - end of the validity span for this bias value

biasValue - Observable-specific Signal Bias value (meters for code and cycle for phase)

getBias

public double getBias(String obs,
                      AbsoluteDate date)

Get the value of the Observable-specific Signal Bias for a given observation type at a given date.

Parameters:

obs - observation type

date - date at which to obtain the Observable-specific Signal Bias

Returns:

the value of the Observable-specific Signal Bias (meters for code and cycle for phase)

getAvailableObservations

public HashSet<String> getAvailableObservations()

Get all available observation types for the satellite.

Returns:

Observation types obtained.

getMinimumValidDateForObservation

public AbsoluteDate getMinimumValidDateForObservation(String obs)

Get the minimum valid date for a given observation type.

Parameters:

obs - observation type

Returns:

minimum valid date for the observation pair

getMaximumValidDateForObservation

public AbsoluteDate getMaximumValidDateForObservation(String obs)

Get the maximum valid date for a given observation type.

Parameters:

obs - observation type

Returns:

maximum valid date for the observation pair

getTimeSpanMap

public TimeSpanMap<Double> getTimeSpanMap(String obs)

Get the TimeSpanMap object for a given observation type, for further operation on the object directly.

Parameters:

obs - observation type

Returns:

the time span map for a given observation code pair
