Description
Multi-messenger astronomy is a flourishing field that seeks to combine signals from many experiments to characterize astrophysical objects and events. These experiments use a huge number of technologies to observe different intermediary particles such as visible, radio-frequency, and X-ray photons; cosmic rays; neutrinos; and gravitational waves. The key to combining these diverse experiments is accurate timing using GPS infrastructure. SNOLAB provides a GPS time server underground. This talk will describe how this server is synced to the global GPS system and what uncertainties are introduced. It will also discuss what equipment can be used by experiments underground to provide accurate timestamps for their data-streams.
