Method Detail

getVersion

public final String getVersion()

Gets the version of this file from line 1.

getPositionVelocityFlag

public final String getPositionVelocityFlag()

Gets the Position/Velocity Flag from Line 1.

getStartEpoch

@Nonnull
public final JulianDate getStartEpoch()

Gets the Start epoch, made from the epoch year, month, day, hour, minute and second from line 1.

getNumberOfEpochs

public final long getNumberOfEpochs()

Gets the number of epochs listed in this file. From line 1.

getDataUsedDescriptor

public final String getDataUsedDescriptor()

Gets the Data Used Descriptor, from Line 1.

getCoordinateSystem

public final String getCoordinateSystem()

Gets the coordinate System from Line 1.

getOrbitType

public final String getOrbitType()

Gets the orbit type from line 1.

getAgency

public final String getAgency()

Gets the generating agency from line 1.

getStartEpochGps

@Nonnull
public final GlobalPositioningSystemDate getStartEpochGps()

Gets the Start epoch in GPS time format, derived from the GPS week and time of week in line 2.

getEpochInterval

public final double getEpochInterval()

Gets the epoch interval from line 2.

getStartModifiedJulianDate

public final int getStartModifiedJulianDate()

Gets the start epoch modified Julian date from line 2.

getStartFractionalDay

public final double getStartFractionalDay()

Gets the start epoch fractional day from line 2.

getNumberOfSats

public final int getNumberOfSats()

Gets the number of satellites contained in this file. From line 3.

getPseudoRandomNumbers

@Nonnull
public final ArrayList<Integer> getPseudoRandomNumbers()

getAccuracies

@Nonnull
public final ArrayList<Integer> getAccuracies()

Gets the orbital accuracy exponent as listed in the header on lines 8-12. The accuracy is interpreted as 2**exponent meters. An exponent value of 0 indicates the accuracy is unknown. The accuracies are ordered identically to the PRN ordering in PseudoRandomNumbers (get).

getComment

public final String getComment()

Gets the comment lines 19-22.
