Constructor Details

IIRVEphemeris

public IIRVEphemeris(IIRVSegment segment)

Constructs a IIRVSegment instance.

An IIRV file contains ephemeris data for a single satellite; thus each IIRVEphemerisFile.IIRVEphemeris instance contains only a single IIRVSegment.

Parameters:

segment - ephemeris segments

Method Details

getId

public String getId()

Get the satellite ID. The satellite ID is unique only within the same ephemeris file.

Specified by:

getId in interface EphemerisFile.SatelliteEphemeris<TimeStampedPVCoordinates,IIRVSegment>

Returns:

the satellite's ID, never null.

getMu

public double getMu()

Get the standard gravitational parameter for the satellite.

Specified by:

getMu in interface EphemerisFile.SatelliteEphemeris<TimeStampedPVCoordinates,IIRVSegment>

Returns:

the gravitational parameter used in EphemerisFile.SatelliteEphemeris.getPropagator(AttitudeProvider), in m³/s².

getSegment

public IIRVSegment getSegment()

Get the IIRVSegment for this satellite.

Returns:

IIRVSegment for this satellite.

See Also:

• getSegment()

getSegments

public List<IIRVSegment> getSegments()

Get the segments of the ephemeris.

Ephemeris segments are typically used to split an ephemeris around discontinuous events, such as maneuvers.

Specified by:

getSegments in interface EphemerisFile.SatelliteEphemeris<TimeStampedPVCoordinates,IIRVSegment>

Returns:

the segments contained in the ephemeris file for this satellite.

getStart

public AbsoluteDate getStart()

Get the start date of the ephemeris.

The date returned by this method is equivalent to getPropagator().getMinDate().

Specified by:

getStart in interface EphemerisFile.SatelliteEphemeris<TimeStampedPVCoordinates,IIRVSegment>

Returns:

ephemeris start date.

getStop

public AbsoluteDate getStop()

Get the end date of the ephemeris.

The date returned by this method is equivalent to getPropagator().getMaxDate().

Specified by:

getStop in interface EphemerisFile.SatelliteEphemeris<TimeStampedPVCoordinates,IIRVSegment>

Returns:

ephemeris end date.

getIIRV

public IIRVMessage getIIRV()

Gets the IIRVMessage containing the ephemeris data for this object's IIRVSegment.

Returns:

IIRVMessage containing the ephemeris data for this object's IIRVSegment.

getStartYear

public int getStartYear()

Gets the start year of the ephemeris data.

Returns:

start year of the ephemeris data
