Tank Object

The Tank object is a base type that provides center of gravity, moment of inertia, orientation, and reference point properties to the objects that derive from it. See the Maneuvering Guide for more information.

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.

Timing Precision Mode

This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.

Name	Description	Attributes
DeclaredName	The name of the object as declared.	Type: String Access: Read-Only
MOI	The tank moment of inertia tensor.	Type: Matrix Access: Read-Only Units: kg m^2
Name	The name displayed for this object in output windows such as views, plots, and reports.	Type: String 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
TankCenterOfGravity	The center of gravity associated with the fuel mass in the tank. This location is determined based on the tank's reference location, fill line orientation, tank volume, fuel mass, and fuel density. The location is referenced from the origin of the Spacecraft BCS and is measured in meters.	Type: Array Access: Read-Only Units: m
TankOrientation	The unit vector in the Spacecraft body coordinate system that defines the primary axis (or z-axis) of the tank. The tank's fill line is oriented perpendicular to this axis. The tank's center of gravity is determined based on this fill line orientation, the tank reference location, tank volume, fuel mass, and fuel density.	Type: Array Access: Read/Write
TankReference	The geometric center of the tank. This location is referenced from the origin of the Spacecraft BCS. The tank's center of gravity is determined based on this reference location, the fill line orientation, tank volume, fuel mass, and fuel density.	Type: Array Access: Read/Write Units: m

Name	Description
ClearSavedStates	Clears previous saved states for this object.
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.

TankCOGX

The X-component of the center of gravity associated with the fuel mass in the tank. This location is determined based on the tank's reference location, fill line orientation, tank volume, fuel mass, and fuel density. The location is referenced from the origin of the Spacecraft BCS and is measured in meters.
