Module error_metrics 

Position-error metrics from supplied covariance matrices.

The functions in this module consume a covariance supplied by another solver and report standard radial accuracy scalars. No covariance estimation is performed here.

Structs

ErrorEllipse

A horizontal one-sigma error ellipse.

PercentileRadius

A percentile circle or sphere radius.

PositionErrorMetrics

Standard position-error metrics from one ENU covariance.

Enums

ErrorMetricsError

Error returned by position-error metric functions.
