Hi Jim,

Welcome to the Orekit mailing lists.

It looks like you're only applying the bias in the getPVCoordinates method. Have you considered extending PVCoordinatesProvider instead of Orbit? The Orbit class hierarchy is used to represent different types of orbital elements at a single instant in time, though they can be either osculating or mean elements. From my limited understanding of your problem I think you would be better served implementing a PVCP or extending a Propagator if you need event detection and step handlers. Is there a reason it needs to be an Orbit?
