Abstract
A new approach for designing satellite constellations whereby the satellites are distributed into contiguous groups forming longitudinal lengths at least equal to 360 degrees. Gaps between the contiguous groups are uniformly distributed along the tracks. These contiguous groups of satellites may be populated by having multiple satellites onboard a single launch vehicle, whereby the satellites are nested into multiple common ground track sub-constellations to form a constellation with multiple common ground tracks.
