               Inertia inertia)

Simple constructor.

Parameters:

commentsBlock - general comments block

epoch - epoch of the data

quaternionBlock - quaternion logical block (may be null in ADM V2 or later)

eulerBlock - Euler angles logicial block (may be null)

angularVelocityBlock - angular velocity block (may be null)

spinStabilizedBlock - spin-stabilized logical block (may be null)

inertia - inertia logical block (may be null)

Method Detail

validate

public void validate(double version)

Check is all mandatory entries have been initialized.

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

Specified by:

validate in interface Section

Parameters:

version - format version

getComments

public List<String> getComments()

Get the comments.

Returns:

comments

getEpoch

public AbsoluteDate getEpoch()

Get the epoch of the data.

Returns:

epoch the epoch

Since:

12.0

getQuaternionBlock

public ApmQuaternion getQuaternionBlock()

Get the quaternion logical block.

Returns:

quaternion block

getEulerBlock

public Euler getEulerBlock()

Get the Euler angles logical block.

Returns:

Euler angles block (may be null)

getAngularVelocityBlock

public AngularVelocity getAngularVelocityBlock()

Get the angular velocity logical block.

Returns:

angular velocity block (may be null)

Since:

12.0

getSpinStabilizedBlock

public SpinStabilized getSpinStabilizedBlock()

Get the spin-stabilized logical block.

Returns:

spin-stabilized block (may be null)

getInertiaBlock

public Inertia getInertiaBlock()

Get the inertia logical block.

Returns:

inertia block (may be null)

getNbManeuvers

public int getNbManeuvers()

Get the number of maneuvers present in the APM.

Returns:

the number of maneuvers

getManeuvers

public List<Maneuver> getManeuvers()

Get a list of all maneuvers.

Returns:

unmodifiable list of all maneuvers.

getManeuver

public Maneuver getManeuver(int index)

Get a maneuver.

Parameters:

index - maneuver index, counting from 0

Returns:

maneuver

addManeuver

public void addManeuver(Maneuver maneuver)

Add a maneuver.

Parameters:

maneuver - maneuver to be set

hasManeuvers

public boolean hasManeuvers()

Get boolean testing whether the APM contains at least one maneuver.

Returns:

true if APM contains at least one maneuver false otherwise

getAttitude

public Attitude getAttitude(Frame frame,
                            PVCoordinatesProvider pvProvider)

Get the attitude.

Parameters:

frame - reference frame with respect to which attitude must be defined, (may be null if attitude is not orbit-relative and one wants attitude in the same frame as used in the attitude message)

pvProvider - provider for spacecraft position and velocity (may be null if attitude is not orbit-relative)

Returns:

attitude
