Attributes
|
AngularVelocity
|
The angular velocity vector associated with the quaternion attitude system. The angular velocity will be applied with respect to the attitude frame defined by the Vehicle.AttitudeRefFrame property.
|
Type: Array
Access: Read/Write
Units: deg/s
|
Annotation
|
When displayed in a Mission View the specified text will be drawn at each tail point. The value may be modified between updates to change the text drawn at subsequent points.
|
Type: String
Access: Read/Write
|
AttitudeMatrix
|
The Direction-Cosine-Matrix (DCM) that defines the rotation from the specified Attitude Reference Frame to the Vehicle Body Coordinate System.
|
Type: Matrix
Access: Read/Write
|
AttitudeRefFrame
|
This is the Vehicle's attitude reference frame. It is necessary to define the AttitudeRefFrame property of the Vehicle prior to defining the attitude system properties.
|
Type: String
Access: Read/Write
|
AttitudeSystem
|
Specifies which attitude system set defines the Vehicle state.
|
Type: String
Access: Read/Write
|
BodyScale
|
A scale factor to increase or decrease the size of the Vehicle model in a Mission View. The BodyScale property assumes the model dimensions are in units of meters, similar to the ThreeDModel.Scale property. If, for example, the ThreeDModel.Scale is set to 1, the Vehicle.BodyScale will have to be set to 1 in order to make bounding boxes coincide with the model.
|
Type: Variable
Access: Read/Write
|
CentralBodyObject
|
CelestialObject that defines the origin for the Vehicle's position and velocity.
|
Type: CelestialObject
Access: Read-Only
|
Color
|
The color of the Vehicle tail when displayed in a Mission View. The color can be overridden for an individual view using the ViewWindow.SetObjectColor() method.
|
Type: Variable
Access: Read/Write
|
DeclaredName
|
The name of the object as declared.
|
Type: String
Access: Read-Only
|
DisplayName
|
The name displayed for this object in output windows such as views, plots, and reports.
|
Type: String
Access: Read/Write
|
ElapsedTime
|
Returns the time passed since the first time this property is read on a specific line of script.
|
Type: TimeSpan
Access: Read-Only
Units: day
|
Epoch
|
The current Vehicle date and time in International Atomic Time (TAI) in the Modified Julian Date format. The returned value has units of days, measured from January 5, 1941 at 12:00:00.000 TAI.
Changing the value of this property does not cause the Vehicle's state to be propagated - the Vehicle's state will not be changed. In order to propagate a Vehicle to a desired epoch, use the Step command.
|
Type: TimeSpan
Access: Read/Write
Units: day
|
EulerAngles
|
These are the angles associated with the Euler attitude system. These angles will be applied as a set of three rotations to the Vehicle's attitude about the axes set in the Vehicle.EulerSequence property.
|
Type: Array
Access: Read/Write
Units: deg
|
EulerRates
|
Rate of change of the Euler angles.
|
Type: Array
Access: Read/Write
Units: deg/s
|
EulerSequence
|
Axes of rotation that the EulerAngles are around.
|
Type: Array
Access: Read/Write
|
FixedPosition
|
Reports the object's position components (X, Y, Z) referenced to the Body Fixed coordinate system of its central body.
|
Type: Array
Access: Read-Only
Units: km
|
HistoryMode
|
Determines if the visualized Vehicle tail is unlimited in length, or whether new points replace the oldest points once the tail exceeds the Vehicle tail length. The history mode can be overridden for an individual view using ViewWindow.SetObjectHistoryMode() method.
|
Type: Variable
Access: Read/Write
|
ObjectId
|
The unique identifier for the object.
|
Type: Variable
Access: Read-Only
|
ObjectType
|
The type of the object.
|
Type: String
Access: Read-Only
|
Position
|
Returns the Vehicle's X, Y, Z position referenced to the ICRF.
|
Type: Array
Access: Read/Write
Units: km
|
Propagator
|
The propagator for updating the state of the Vehicle.
|
Type: Propagator
Access: Read-Only
|
Quaternion
|
Returns the four components of the attitude quaternion of a Vehicle. The first three components represent the vector part of the quaternion, the last component represents the scalar part. FreeFlyer uses the right-handed convention when applying the quaternion rotation.
|
Type: Array
Access: Read/Write
|
Sensors
|
The Vehicle's sensors.
|
Type: Array of Sensor
Access: Read-Only
|
TailLength
|
The number of historical position points to save and draw in visualizations generated using the View command. A new point will be added each time the View command is called. If you use a ViewWindow object, the tail length set there will override this tail length.
In millisecond timing precision mode only, the deprecated "as Global" syntax can be used to update the View when any Vehicle is Stepped or Maneuvered.
Use caution in setting tail lengths longer than 10,000 - 30,000 points. Tail lengths exceeding this range can cause memory problems due to the large amount of relative position data that must be maintained. The maximum tail length that can be used safely depends on the amount of memory in the system and the number of objects managed by the Mission View.
