Description
The EstimableLatLongBias object holds information about how latitude and longitude bias elements of an object's state are handled in the Orbit Determination / State Estimation process. This object is not creatable in script, but estimable lat/lon biases are always created as child objects of the GroundStationODProperties object as seen in the example below:
GroundStation1.OD.LatitudeBias.Sigma = 1e-006;
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.

Description
|
DeclaredName
|
The name of the object as declared.
|
DisplayName
|
The name displayed for this object in output windows such as views, plots, and reports.
|
ObjectId
|
The unique identifier for the object.
|
ObjectType
|
The type of the object.
|
ProcessAction
|
Indicates whether the property should be estimated, considered, or ignored in the Orbit Determination process.
|
ProcessNoise
|
The process noise to be added to the property's covariance with each time-step. The amount of process noise added is scaled by a ratio of the duration of the step taken and the propagator step size.
|
Sigma
|
Specifies the uncertainty (standard deviation) in the value of the property.
|
SmoothedValue
|
The smoothed value of the property when the property is estimated in Kalman Filter / Smoother combination.
|
StateUpdate
|
The value of the state update that is applied to this property when it is estimated in an Orbit Determination process.
|
Value
|
The current value of the property.

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
|
