A satellite system may have a constellation of communications satellites that provides services to users with electronic devices such as portable electronic devices and home/office equipment. A network operations center may use gateways to communicate with the satellite constellation. The satellite constellation may include sets of satellites with different orbits such as circular orbits with different inclinations, sets of satellites with elliptic orbits, sets of satellites with circular orbits of different altitudes including low earth orbits, medium earth orbits, and/or geosynchronous orbits, sets of satellites with sun synchronous orbits, and/or sets of satellites with other orbits. The orbits of the satellites in the constellation may be selected to provide coverage to desired user population concentrations at different locations on the Earth, while reducing the amount of capacity that goes unused (e.g., is idle) at one or more times of day.
