Description
The EstimableEquinoctialLongitude object holds information about how the mean longitude (from the Equinoctial element set) of a Spacecraft state is handled in the Orbit Determination / State Estimation process. This object is not creatable in script, but EstimableEquinoctialLongitude is always created as a child object of the EquinoctialOrbitStateEstimablePropertyContainer and Sgp4OrbitStateEstimablePropertyContainer objects, as seen below:
Spacecraft1.OD.Equinoctial.Longitude.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.

ProcessAction
|
Indicates whether the property should be estimated, considered, or ignored in the Orbit Determination process.
|
Type: Variable
Access: Read/Write
