Description
|
AprioriCovarianceOption
|
The options for how the a priori covariance is handled through the iteration process.
|
ConstrainDataSpan
|
Flag indicating whether or not to constrain the data span based on the values of SpanStartEpoch and SpanEndEpoch.
|
Covariance
|
The Covariance associated with the ODEstimationProcess.
|
DeclaredName
|
The name of the object as declared.
|
InformationMatrix
|
The information matrix in the MJ2000 equatorial frame associated with all properties to be estimated. This is a read-only property representing the information matrix after the accumulation of all the observations. This strictly represents the inverse of the post update covariance. A priori values of the information matrix should be set through the apriori covariance of the state elements.
|
InformationMatrixInversionMethod
|
The method used to invert the information matrix. By default, the matrix is inverting using a full-pivot approach, but if the information matrix is not well-conditioned, then either a scaled full-pivot inversion will occur, if possible, or as a last resort, a Moore-Penrose pseudo-inverse will be used.
|
IterationCount
|
The number of iterations that have been processed.
|
MaxAllowableSigma
|
The sigma tolerance to be applied when editing observation data.
|
MeasurementEditingOption
|
The options for how measurement data will be evaluated for inclusion in processing.
|
MinimumNumberOfMeasurementsForSigmaEditing
|
The minimum number of measurements required for a measurement type to be sigma edited. This property is only applied when the Measurement Editing Option is set to 'Use the Standard Deviation'
|
Name
|
The name displayed for this object in output windows such as views, plots, and reports.
|
ObjectId
|
The unique identifier for the object.
|
ObjectsToProcess
|
Array of objects that have been included in the Orbit Determination process.
|
ObjectType
|
The type of the object.
|
Observations
|
An array of Observations that have been processed by the BatchLeastSquaresOD object.
|
PredictedRMS
|
The predicted Root-Mean-Square (RMS) of the measurement residuals for the next iteration.
|
RegisteredTrackingDataFiles
|
Array of TrackingDataFile objects used to provided observations for the ODEstimationProcess.
|
RMS
|
The Root-Mean-Square (RMS) of the measurement residuals for the current iteration.
|
SolutionDampingAlpha
|
The computed Alpha value from the Quadratic Solution Damping algorithm. This term is used to scale the state update for a given iteration and adjust the Damping Factor on the subsequent iteration when the computed Rho is greater than the specified tolerance.
|
SolutionDampingFactor
|
The damping factor for the Levenberg-Marquardt algorithm. This value is updated based on the results of each iteration of processing.
|
SolutionDampingFactorDecrease
|
The magnitude of decrease in the damping factor for the Levenberg-Marquardt algorithm. If the iteration improves the residuals, the DampingFactor is decreased as: DampingFactor = DampingFactor/DampingFactorDecrease. This property is only used if the SolutionDampingOption is set to 'Use Levenberg-Marquardt'.
|
SolutionDampingFactorIncrease
|
The magnitude of increase in the damping factor for the Levenberg-Marquardt algorithm. If the iteration does not improve the residuals, the DampingFactor is increased as: DampingFactor = DampingFactor*DampingFactorIncrease. This property is only used if the SolutionDampingOption is set to 'Use Levenberg-Marquardt'.
|
SolutionDampingOption
|
The options for damping the convergence of the solution.
|
SolutionDampingRho
|
The computed Rho value from the Solution Damping algorithm. This computed value is compared against the tolerance and used to determine if a state update for a given iteration improves the state estimate. If the state estimate is improved, the Damping Factor is decreased on the subsequent iteration; if it did not improve, the Damping Factor is increased.
|
SolutionDampingRhoTolerance
|
The Rho value threshold for the Solution Damping algorithm. If the computed Rho value is greater than this threshold, then the Damping Factor is decreased on the next iteration, and for the Quadratic Damping algorithm, state update is scaled based on the computed Alpha value.
|
SolutionEpoch
|
The epoch at which the State Update will be calculated and applied. If the SolutionEpochOption property is not set to "User Specified Epoch" then setting this has no affect, but reading will reflect the appropriate value in the data span.
|
SolutionEpochOption
|
The options for the Solution Epoch.
|
SpanEndEpoch
|
The epoch at the end of the span of the data to be processed. By default this epoch is taken from the last observation that is included in the buffer to be processed. If the user sets this property to a value less than the epoch of the last observation, it will constrain the data span, ignoring observations with an epoch after this value.
|
SpanStartEpoch
|
The epoch at the start of the span of the data to be processed. By default this epoch is taken from the first observation that is included in the buffer to be processed. If the user sets this property to a value greater than the epoch of the first observation, it will constrain the data span, ignoring observations with an epoch prior to this value.
|
StepSize
|
The maximum step size used when propagating the Covariance.
|
ThrustEventsToModel
|
Array of Maneuver objects to be modeled as part of the propagation for the orbit determination process.
|
WeightedRMS
|
The weighted Root-Mean-Square (RMS) of the measurement residuals for the current iteration.
