Abstract
Methods and systems for providing voice, video, or data services using optimized ground track satellites and ground tracking antennas are disclosed herein. An example system includes first satellites in a first constellation, the first satellites having a first fixed ground track relative to Earth's surface, and an antenna being located at a location on the first fixed ground track, the antenna being configured to steer in a single axis to track the first satellites, wherein each of the first satellites reach the location, after an integer number of days that include a period of two or more sidereal days with an adjustment to account for nodal precession of the first satellites.
