Sidereon.GeometryQuality (Sidereon v0.22.0)

Geometry observability and covariance-validation diagnostics.

The tier field classifies the solve design as:

:rank_deficient - at least one parameter is not observable.
:zero_redundancy - full rank, but no residual degrees of freedom.
:weak - full rank with residual degrees of freedom, but above a condition-number or GDOP cutoff.
:nominal - full rank and within the configured cutoffs.

:zero_redundancy bounds are not validated unless covariance_validated is true. :weak bounds are reported without clamping.

Summary

Types

observability_tier()
