Satellite constellations using nodally-adjusted repeating ground track orbits

A satellite system and method is disclosed. The satellite system comprises a satellite constellation including a plurality of satellites orbiting a planet to provide a coverage pattern of the planet. The plurality of satellites includes one or more satellites in circular orbits and at least one satellite of the plurality of satellites in an elliptical orbit. Each of the plurality of satellites has substantially the same nodal regression rate. An exemplary constellation uses an inclination of substantially 63.43°. The elliptical orbit can be implemented by a refuelable satellite used to make low perigee passes over a location of interest.
