ABSTRACT:
A man-made satellite (1) traveling in an elliptical orbit. The orbit has five or six daily apogees, which are positioned above the same longitudes of the earth at substantially the same local time-of-day for each day of the year. The longitudes and times-of-day can be preselected subject only to the proviso that they be equispaced. The apsidal rotation rate in inertial space (ARRIS) of the orbit is substantially equal to the mean rate at which the earth revolves about the sun. The orbit is preferably equatorial, in order to simplify ground tracking and to maximize the impact of the apsidal rotation.
