Modern neutrino facilities will be able to detect a large number of neutrinos
from the next Galactic supernova. We investigate the viability of the
triangulation method to locate a core-collapse supernova by employing the
neutrino arrival time differences at various detectors. We perform detailed
numerical fits in order to determine the uncertainties of these time
differences for the cases when the core collapses into a neutron star or a
black hole. We provide a global picture by combining all the relevant current
and future neutrino detectors. Our findings indicate that in the scenario of a
neutron star formation, supernova can be located with precision of 1.5 and 3.5
degrees in declination and right ascension, respectively. For the black hole
scenario, sub-degree precision can be reached.
