Equivalent Generic Forms for Metric Fields Yielded by Relativistic
Positioning Systems    [PDF]

Relativistic positioning systems provide tensors represented in $\{\ell\ell\ell\ell\}$-frames ($\ell$ for light). We show, in particular, that any Lorentzian metric field given in such a frame is equivalent to a generic metric field defined by four positive functions.
