Constructor Details

OrekitSatelliteAttitudeEphemeris

public OrekitSatelliteAttitudeEphemeris(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 AttitudeEphemerisFile.SatelliteAttitudeEphemeris<TimeStampedAngularCoordinates,OrekitAttitudeEphemerisFile.OrekitAttitudeEphemerisSegment>

Returns:

the satellite's ID, never null.

getSegments

public List<OrekitAttitudeEphemerisFile.OrekitAttitudeEphemerisSegment> getSegments()

Get the segments of the attitude ephemeris.

Attitude ephemeris segments are typically used to split an ephemeris around discontinuous events.

Specified by:

getSegments in interface AttitudeEphemerisFile.SatelliteAttitudeEphemeris<TimeStampedAngularCoordinates,OrekitAttitudeEphemerisFile.OrekitAttitudeEphemerisSegment>

Returns:

the segments contained in the attitude ephemeris file for this satellite.

getStart

public AbsoluteDate getStart()

Get the start date of the ephemeris.

Specified by:

getStart in interface AttitudeEphemerisFile.SatelliteAttitudeEphemeris<TimeStampedAngularCoordinates,OrekitAttitudeEphemerisFile.OrekitAttitudeEphemerisSegment>

Returns:

ephemeris start date.

getStop

public AbsoluteDate getStop()

Get the end date of the ephemeris.

Specified by:

getStop in interface AttitudeEphemerisFile.SatelliteAttitudeEphemeris<TimeStampedAngularCoordinates,OrekitAttitudeEphemerisFile.OrekitAttitudeEphemerisSegment>

Returns:

ephemeris end date.

addNewSegment

public OrekitAttitudeEphemerisFile.OrekitAttitudeEphemerisSegment addNewSegment(List<SpacecraftState> states,
 String interpolationMethod,
 int interpolationSamples,
 AngularDerivativesFilter availableDerivatives)

Injects pre-computed satellite states into this attitude ephemeris file object, returning the generated OrekitAttitudeEphemerisFile.OrekitAttitudeEphemerisSegment that has been stored internally.

Parameters:

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

interpolationMethod - the interpolation method that should be used when processed by another system

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

availableDerivatives - derivatives to use for interpolation

Returns:

the generated OrekitAttitudeEphemerisFile.OrekitAttitudeEphemerisSegment
