Constructor Detail

STKEphemeris

public STKEphemeris(String satelliteId,
                    double mu,
                    List<STKEphemerisFile.STKEphemerisSegment> segments)

Constructs a STKEphemerisFile.STKEphemeris instance. This constructor shallowly copies the list of segments provided.

Parameters:

satelliteId - satellite id

mu - gravitational parameter (m^3/s^2)

segments - ephemeris segments

Method Detail

getId

public String getId()

Description copied from interface: EphemerisFile.SatelliteEphemeris

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

Specified by:

getId in interface EphemerisFile.SatelliteEphemeris<TimeStampedPVCoordinates,STKEphemerisFile.STKEphemerisSegment>

Returns:

the satellite's ID, never null.

getMu

public double getMu()

Description copied from interface: EphemerisFile.SatelliteEphemeris

Get the standard gravitational parameter for the satellite.

Specified by:

getMu in interface EphemerisFile.SatelliteEphemeris<TimeStampedPVCoordinates,STKEphemerisFile.STKEphemerisSegment>

Returns:

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

getSegments

public List<STKEphemerisFile.STKEphemerisSegment> getSegments()

Description copied from interface: EphemerisFile.SatelliteEphemeris

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,STKEphemerisFile.STKEphemerisSegment>

Returns:

the segments contained in the ephemeris file for this satellite.

getStart

public AbsoluteDate getStart()

Description copied from interface: EphemerisFile.SatelliteEphemeris

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,STKEphemerisFile.STKEphemerisSegment>

Returns:

ephemeris start date.

getStop

public AbsoluteDate getStop()

Description copied from interface: EphemerisFile.SatelliteEphemeris

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,STKEphemerisFile.STKEphemerisSegment>

Returns:

ephemeris end date.
