All Implemented Interfaces:

Section

public class StateVector
extends CommentsContainer

Container for state vector data.

Beware that the Orekit getters and setters all rely on SI units. The parsers and writers take care of converting these SI units into CCSDS mandatory units. The Unit class provides useful fromSi and toSI methods in case the callers already use CCSDS units instead of the API SI units. The general-purpose Unit class (without an 's') and the CCSDS-specific Units class (with an 's') also provide some predefined units. These predefined units and the fromSi and toSI conversion methods are indeed what the parsers and writers use for the conversions.

11.0

This method should throw an exception if some mandatory entries are missing or not compatible with version number.

Specified by:

validate in interface Section

Overrides:

validate in class CommentsContainer

Parameters:

version - format version

getEpoch

public AbsoluteDate getEpoch()

Get epoch of state vector, Keplerian elements and covariance matrix data.

Returns:

epoch the epoch

setEpoch

public void setEpoch(AbsoluteDate epoch)

Set epoch of state vector, Keplerian elements and covariance matrix data.

Parameters:

epoch - the epoch to be set

setP

public void setP(int index,
                 double value)

Set position component.

Parameters:

index - component index (counting from 0)

value - position component

setV

public void setV(int index,
                 double value)

Set velocity component.

Parameters:

index - component index (counting from 0)

value - velocity component

setA

public void setA(int index,
                 double value)

Set acceleration component.

Parameters:

index - component index (counting from 0)

value - acceleration component

hasAcceleration

public boolean hasAcceleration()

Check if state contains acceleration data.

Returns:

true is state contains acceleration data

toTimeStampedPVCoordinates

public TimeStampedPVCoordinates toTimeStampedPVCoordinates()

Convert to TimeStampedPVCoordinates.

Returns:

a new TimeStampedPVCoordinates
