TrajectoryNode Object

The TrajectoryNode object represents an individual node within a TrajectoryPhase object. Nodes represent the discretized path of the TrajectoryPhase. Nodes are added to the underlying TrajectoryNodes of the TrajectoryPhase object through the TrajectoryPhase.AddNode() and TrajectoryPhase.AddNodes() methods.

Users cannot create instances of this type of object. However, users can access instances of this object type that have been created indirectly, for example as children of other objects. Users can also access any static properties and methods on this object type.

Name	Description	Attributes
CartesianState	The TrajectoryNode's position (km) and velocity (km/s) variables in the ICRF.	Type: Array Access: Read-Only
CentralBodyObject	The reference body used by the TrajectoryNode. This property cannot be set directly since it is inherited from the TrajectoryPhase object which owns the TrajectoryNode.	Type: CelestialObject Access: Read-Only
ControlVariables	The TrajectoryNode's control variables. The values and representation of the control variables are dependent on the selection made in the TrajectoryPhase.ControlModel property of the owning phase.	Type: Array Access: Read-Only
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
Epoch	The TrajectoryNode's epoch variable.	Type: TimeSpan Access: Read-Only Units: day
Mass	The TrajectoryNode's mass variable.	Type: Variable Access: Read-Only Units: kg
ObjectId	The unique identifier for the object.	Type: Variable Access: Read-Only
ObjectType	The type of the object.	Type: String Access: Read-Only
Position	The TrajectoryNode's position (km) variables in the ICRF.	Type: Array Access: Read-Only Units: km
Velocity	The TrajectoryNode's velocity (km/s) variables in the ICRF.	Type: Array Access: Read-Only Units: km/s

Name	Description
ClearSavedStates	Clears previous saved states for this object.
GetControlAcceleration	Returns the acceleration due to the control model. For more information on control models, see the TrajectoryPhase.ControlModel property.
GetFromFile	Load the object state from the specified FreeFlyer object file.
GetFromString	Load the object state from the specified string.
PutToFile	Convert the object state to FreeFlyer object xml and write to a file.
PutToString	Convert the object state to FreeFlyer object xml and return as a string.
ReferenceEquals	Returns 1 if the argument refers to the calling object and 0 otherwise.
Restore	Restore an object's state from a previously saved state.
Save	Save the object's state so that it can be restored later.
SetSpacecraftState	Loads the TrajectoryNode's position, velocity, mass, and epoch into the passed Spacecraft. Note: if the Spacecraft's central body differs from the TrajectoryNode's central body, a state conversion will take place automatically before the Spacecraft state is set.
