Covariance estimates are becoming more widely available as flight dynamics operations work to-wards greater accuracy. Investigators have looked at how covariance matrices are propagated, to in-clude orbital state formats and coordinate systems. Various equations to convert between orbital state formats and satellite coordinate systems are essential for proper use and analysis. The litera-ture contains many examples. Vallado (2003) presented a complete set of equations, but advised that a few inconsistencies were found. We have corrected those errors and provide the results. Test results are given for several cases, and MatLab code is available.
