OutgassingEvent Object

The OutgassingEvent object models the unintentional release of propellant from a Spacecraft. The acceleration due to the release is modeled as an exponential decay. OutgassingEvents do not deplete mass from the Spacecraft. See Outgassing Events for more information.

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
AttitudeSystem	Flag denoting the attitude frame in which the thrust event will be applied to the spacecraft.	Type: Variable Access: Read/Write
BurnDirection	The components of the thrust vector in the coordinates of the attitude system specified by the chosen AttitudeSystem.	Type: Array Access: Read/Write Units: km/s^2
DeclaredName	The name of the object as declared.	Type: String Access: Read-Only
EventDuration	The duration of the outgassing event. This is determined based on the TimeConstant and the MinimumMagnitude properties.	Type: Variable Access: Read-Only Units: day
EventStartTime	The offset time from current Spacecraft epoch, to apply the outgassing event. The Spacecraft will be propagated to the offset time using the applicable ForceModel and Propagator properties. A negative offset time can be used.	Type: Variable Access: Read/Write Units: s
ExecutionPhase	Reveals which portion of the event sequence is currently executing.	Type: Variable Access: Read-Only
MinimumMagnitude	The cut-off threshold for modeling the exponentially decaying outgassing event.	Type: Variable Access: Read/Write
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
OD	This property contains the OD settings for all the OutgassingEvent properties that can be estimated.	Type: OutgassingEventODProperties Access: Read-Only
TimeConstant	The time constant of the exponential decay function that is used to model the outgassing event.	Type: Variable Access: Read/Write Units: s

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.
