The OD property that contains all of the OD statistics (Sigma, Process Noise Rate, State Update, etc) associated with the Spacecraft.SGP4.AGOM property.
|
Type: EstimableAGOM
Access: Read-Only
|
BStar
|
The OD property that contains all of the OD statistics (Sigma, Process Noise Rate, State Update, etc) associated with the Spacecraft.SGP4.BStar property.
|
Type: EstimableBStar
Access: Read-Only
|
Cartesian
|
The container of all the OD properties relating to the Cartesian orbit element set.
|
Type: CartesianOrbitStateEstimablePropertyContainer
Access: Read-Only
|
Cd
|
The OD property that contains all of the OD statistics (Sigma, Process Noise Rate, State Update, etc) associated with the Spacecraft.Cd property.
|
Type: EstimableCoefficient
Access: Read-Only
|
Covariance
|
The Covariance associated with this Spacecraft, expressed in the ICRF.
|
Type: SpacecraftCovariance
Access: Read-Only
|
CovariancePropagationModel
|
A flag indicating the method to be used to propagate the Covariance. Specifies the model to use in propagating the spacecraft's covariance. This property is used when propagating the Spacecraft covariance outside of filtering process. When using the KalmanFilterOD object, covariance propagation is always done using the full covariance matrix. When using the SquareRootInformationFilterOD object, square root of the information matrix is used.

The OD property that contains all of the OD statistics (Sigma, Process Noise Rate, State Update, etc) associated with the Spacecraft.Cr property.
|
Type: EstimableCoefficient
Access: Read-Only
|
CustomObservations
|
The array of OD properties that contains all of the measurement and bias properties associated with any user-defined Custom Observations.
|
Type: Array of CustomObservationMeasurements
Access: Read-Only
|
DeclaredName
|
The name of the object as declared.
|
Type: String
Access: Read-Only
|
DragEstimateOption
|
A flag indicating whether Cd or Rho1 should be the method for estimating the drag on the Spacecraft.
|
Type: Variable
Access: Read/Write
|
ElementSetToProcess
|
Indicates the element set to use when estimating the orbit state. Changing this value will reinitialize the process noise matrix to a diagonal matrix in the ICRF frame.
|
Type: String
Access: Read-Only

Access: Read/Write
|
ObjectId
|
The unique identifier for the object.
|
Type: Variable
Access: Read-Only
|
ObjectType
|
The type of the object.

The OD property that contains all of the OD statistics (Sigma, Process Noise Rate, State Update, etc) associated with the Ux property of the Force Model for this Spacecraft.
|
Type: EstimableAcceleration
Access: Read-Only

The OD property that contains all of the OD statistics (Sigma, Process Noise Rate, State Update, etc) associated with the Uy property of the Force Model for this Spacecraft.
|
Type: EstimableAcceleration
Access: Read-Only
|
OtherAccelerationsZ
|
The OD property that contains all of the OD statistics (Sigma, Process Noise Rate, State Update, etc) associated with the Uz property of the Force Model for this Spacecraft.
|
Type: EstimableAcceleration
Access: Read-Only
|
ProcessNoise
|
The Process Noise object associated with this Spacecraft, used for managing the process noise model configuration.
|
Type: SpacecraftProcessNoise
Access: Read-Only
|
ProcessNoiseModel
|
This flag indicates which Process Noise model to apply when propagating the Spacecraft. The 'Process Noise per Step' model will add the amount of process noise specified in the EstimableProperty.ProcessNoise values at each step of the Spacecraft, regardless of the Spacecraft's step size. The 'Process Noise Rate' model, which is the recommended option, will add the amount of process noise specified in the Spacecraft.OD.ProcessNoise.Matrix values, so that the amount of process noise added per step will scale up and down with the duration of the step.
|
Type: Variable
Access: Read/Write
|
PropagateCovariance
|
A flag indicating whether or not to propagate the Spacecraft covariance with each Step command separate from any Orbit Determination process. As a note, if the Spacecraft has been added to any Orbit Determination process, the Orbit Determination process will take precedence and this flag will be ignored. The StepOD() method associated with all the Sequential Filters also performs covariance propagation within an Orbit Determination process.
