Description
The EstimableProperty object is a base type that provides process action, process noise rate, sigma, smoothed value, and state update properties to the objects that derive from it. See the Orbit Determination 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.

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
|
ObjectId
|
The unique identifier for the object.
|

Access: Read-Only
|
ObjectType
|
The type of the object.
|
Type: String
Access: Read-Only
|
ProcessAction
|
Indicates whether the property should be estimated, considered, or ignored in the Orbit Determination process. If this property is part of a Spacecraft, which also has a process noise matrix interface, then changing this value will reinitialize the process noise matrix to a diagonal matrix in the ICRF frame.

Type: Variable
Access: Read/Write
|
Sigma
|
Specifies the uncertainty (standard deviation) in the value of the property.
|
Type: Variable
Access: Read/Write
|
SmoothedValue
|
The smoothed value of the property when the property is estimated in Kalman Filter / Smoother combination.
|
Type: Variable
Access: Read-Only
|
StateUpdate
|
The value of the state update that is applied to this property when it is estimated in an Orbit Determination process.
|
Type: Variable
Access: Read-Only
|
Value
|
The current value of the property.
|
Type: Variable

|
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
|

ProcessNoise
|
Specifies the amount of process noise to add to the diagonal elements of the covariance matrix with each time-step for this property.
This property has been Deprecated. Please use ProcessNoiseRate instead, and be sure to convert units appropriately when updating.
