Constructor Details

OrekitSatelliteEphemeris

public OrekitSatelliteEphemeris(String id)

Standard constructor for building the satellite Ephemeris object.

Parameters:

id - the ID of the space object for this data

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,OrekitEphemerisFile.OrekitEphemerisSegment>

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,OrekitEphemerisFile.OrekitEphemerisSegment>

Returns:

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

getSegments

public List<OrekitEphemerisFile.OrekitEphemerisSegment> 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,OrekitEphemerisFile.OrekitEphemerisSegment>

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,OrekitEphemerisFile.OrekitEphemerisSegment>

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,OrekitEphemerisFile.OrekitEphemerisSegment>

Returns:

ephemeris end date.

addNewSegment

@DefaultDataContext
public OrekitEphemerisFile.OrekitEphemerisSegment addNewSegment(List<SpacecraftState> states)

Injects pre-computed satellite states into this ephemeris file object, returning the generated OrekitEphemerisFile.OrekitEphemerisSegment that has been stored internally. Defaults the celestial body to earth and the interpolation size to the default.

This method uses the default data context.

Parameters:

states - a list of SpacecraftState that will comprise this new unit.

Returns:

the generated OrekitEphemerisFile.OrekitEphemerisSegment

See Also:

• addNewSegment(List, CelestialBody, int, TimeScale)

addNewSegment

@DefaultDataContext
public OrekitEphemerisFile.OrekitEphemerisSegment addNewSegment(List<SpacecraftState> states,
 int interpolationSampleSize)

Injects pre-computed satellite states into this ephemeris file object, returning the generated OrekitEphemerisFile.OrekitEphemerisSegment that has been stored internally. Defaults the Celestial Body to be Earths

This method uses the default data context.

Parameters:

states - a list of SpacecraftState that will comprise this new unit.

interpolationSampleSize - the number of interpolation samples that should be used when processed by another system

Returns:

the generated OrekitEphemerisFile.OrekitEphemerisSegment

See Also:

• addNewSegment(List, CelestialBody, int, TimeScale)

Returns:

the generated OrekitEphemerisFile.OrekitEphemerisSegment

See Also:

• addNewSegment(List, CelestialBody, int, TimeScale)

addNewSegment

public OrekitEphemerisFile.OrekitEphemerisSegment addNewSegment(List<SpacecraftState> states,
 CelestialBody body,
