The design and implementation of the LCO Network is aimed at providing capabilities uniquely suited for astronomical time domain studies. The telescopes of a given aperture and their instruments are identical and state-of-the-art.

The scheduler automatically adjusts schedules of individual telescopes continuously as needed. Monitoring observations can be passed off from site to site, and observations can be interrupted for targets of opportunity very quickly.
