Constructor Detail

OemSatelliteEphemeris

public OemSatelliteEphemeris(String id,
                             double mu,
                             List<OemSegment> blocks)

Create a container for the set of ephemeris blocks in the file that pertain to a single satellite.

Parameters:

id - id of the satellite.

mu - gravitational coefficient to use for building Cartesian/Keplerian orbits

blocks - containing ephemeris data for the satellite.

Method Detail

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,OemSegment>

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,OemSegment>

Returns:

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

getSegments

public List<OemSegment> 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,OemSegment>

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,OemSegment>

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,OemSegment>

Returns:

ephemeris end date.
