Visibility of the Earth's surface by spacecraft in Earth-Moon Libration Point Orbits (LPOs) at L1 and L3 is examined. Coverage is computed for single satellites and constellations of spacecraft. Initially, coverage is analyzed in the model formulated by the Circular Restricted Three-Body Problem. Coverage is also computed in the full ephemeris. A constellation consisting of one spacecraft in an L1 orbit and two spacecraft in reciprocal northern/southern L3 orbits can provide nearly continuous global coverage of the Earth's surface.
