Method Summary

Modifier and Type	Method	Description
protected void	cycleSlipDataSet(String nameSat, AbsoluteDate date, double value, Frequency freq)	Set the data: collect data at the current Date, at the current frequency, for a given satellite, add it within the attributes data and stuff.
List<CycleSlipDetectorResults>	detect(List<ObservationDataSet> observations)	Detects if a cycle-slip occurs for a given list of observation data set.
protected double	getMaxTimeBeetween2Measurement()	Get the maximum time lapse between 2 measurements without considering a cycle-slip has occurring between both.
protected int	getMinMeasurementNumber()	Get the minimum number of measurement needed before being able to figure out cycle-slip occurrence.
protected List<CycleSlipDetectorResults>	getResults()	Get on all the results computed by the detector (e.g.: dates of cycle-slip).
protected List<Map<Frequency,org.orekit.estimation.measurements.gnss.AbstractCycleSlipDetector.DataForDetection>>	getStuffReference()	Get the stuff (all the things needed for, the detector).
protected abstract void	manageData(ObservationDataSet observation)	The method is in charge of collecting the measurements, manage them, and call the detection method.
protected String	setName(int numSat, SatelliteSystem sys)	Create the name of a satellite from its PRN number and satellite System it belongs to.

Method Detail

detect

public List<CycleSlipDetectorResults> detect(List<ObservationDataSet> observations)

Detects if a cycle-slip occurs for a given list of observation data set.

Specified by:

detect in interface CycleSlipDetectors

Parameters:

observations - list of observation data set

Returns:

a list of results computed by the cycle-slip detectors

manageData

protected abstract void manageData(ObservationDataSet observation)

The method is in charge of collecting the measurements, manage them, and call the detection method.

Parameters:

observation - observation data set

getMinMeasurementNumber

protected int getMinMeasurementNumber()

Get the minimum number of measurement needed before being able to figure out cycle-slip occurrence.

Returns:

the minimum number of measurement needed before being able to figure out cycle-slip occurrence.

getMaxTimeBeetween2Measurement

protected double getMaxTimeBeetween2Measurement()

Get the maximum time lapse between 2 measurements without considering a cycle-slip has occurring between both.

Returns:

the maximum time lapse between 2 measurements

getResults

protected List<CycleSlipDetectorResults> getResults()

Get on all the results computed by the detector (e.g.: dates of cycle-slip).

Returns:

all the results computed by the detector (e.g.: dates of cycle-slip).

getStuffReference

protected List<Map<Frequency,org.orekit.estimation.measurements.gnss.AbstractCycleSlipDetector.DataForDetection>> getStuffReference()

Get the stuff (all the things needed for, the detector).

Returns:

return stuff

cycleSlipDataSet

protected void cycleSlipDataSet(String nameSat,
                                AbsoluteDate date,
                                double value,
                                Frequency freq)

Set the data: collect data at the current Date, at the current frequency, for a given satellite, add it within the attributes data and stuff.

Parameters:

nameSat - name of the satellite (e.g. "GPS - 7")

date - date of the measurement

value - measurement at the current date

freq - frequency used

setName

protected String setName(int numSat,
                         SatelliteSystem sys)

Create the name of a satellite from its PRN number and satellite System it belongs to.

Parameters:

numSat - satellite PRN number

sys - Satellite System of the satellite

Returns:

the satellite name on a specified format (e.g.: "GPS - 7")
