We derive an expression for the accuracy with which sources can be localized using a network of gravitational wave detectors. The result is obtained via triangulation, using timing accuracies at each detector and is applicable to a network with any number of detectors. We use this result to investigate the ability of advanced gravitational wave detector networks to accurately localize signals from compact binary coalescences. We demonstrate that additional detectors can significantly improve localization results and illustrate our findings with networks comprised of the advanced LIGO, advanced Virgo and LCGT. In addition, we evaluate the benefits of relocating one of the advanced LIGO detectors to Australia.

Binary Black Hole Mergers in the First Advanced LIGO Observing Run (2016, background): “Since the source of GW151226 merged at about 450 Hz, the signal provides the opportunity to probe the PN inspiral with many more waveform cycles, albeit at relatively low SNR.”
Prospects for observing and localizing gravitational-wave transients with Advanced LIGO, Advanced Virgo and KAGRA (2013, background): “An intuitive understanding of localization can be gained by considering triangulation using the observed time delays between sites (Fairhurst 2009, 2011).”
Prospects for Observing and Localizing Gravitational-Wave Transients with Advanced LIGO and Advanced Virgo (2013, background): “An intuitive understanding of localization can be gained by considering triangulation using the observed time delays between sites [55, 56].”
Networks of gravitational wave detectors and three figures of merit (2011, methodology): “Several of these networks have recently been studied also by Fairhurst [45] who concentrated on the localization ability, using a different approach than that adopted here, and one that is closer to the present methods of data analysis based on thresholding.”
