Description
The Sgp4OrbitStateEstimablePropertyContainer object provides a collection of the SGP4 estimable properties for use when estimating the Spacecraft state in the SGP4 element set. This object is not creatable in script, but is always created as a child object of the SpacecraftODProperties object, as seen below:
Spacecraft1.OD.SGP4.MeanMotion.Sigma = 0.001;
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.
