SPHiNX is a proposed gamma-ray burst (GRB) polarimeter mission operating in
the energy range 50-600 keV with the aim of studying the prompt emission phase.
The polarisation sensitivity of SPHiNX reduces as the uncertainty on the GRB
sky position increases. The stand-alone ability of the SPHiNX design to
localise GRB positions is explored via Geant4 simulations. Localisation at the
level of a few degrees is possible using three different routines. This results
in a large fraction (> 80%) of observed GRBs having a negligible (< 5%)
reduction in polarisation sensitivity due to the uncertainty in localisation.
