Internal lunar ranging leaves a six-dimensional rigid-body datum defect; Earth-baseline VLBI restores absolute station observability for sparse constellations and only sharpens the CRLB for rich ones, closing at three non-collinear Earth stations.

Earth-baseline VLBI restores the observability of a lunar surface station in joint orbit-and-clock determination
Internal lunar ranging leaves a six-dimensional rigid-body datum defect; Earth-baseline VLBI restores absolute station observability for sparse constellations and only sharpens the CRLB for rich ones, closing at three non-collinear Earth stations.
