Patent attributes
A system includes a satellite fleet (102, FIG. 1), in which each satellite receives uplink signals from an uplink hub (104), and transmits downlink signals in at least one directed beam (112). In an embodiment, downlink signals include television content, which is transmitted within a frequency range between about 3.7 and 4.2 Gigahertz. The satellites follow Molniya orbits (1001-1006, FIG. 10), orbit nodes are equally separated, and the satellite phasing is maintained to provide continuous communication within a coverage area. A system also includes user equipment systems (1300, FIG. 13), which include highly-directional, non-tracking antennas (1302) adapted to receive the downlink signals. In an embodiment, a method includes the satellites maintaining orbit phasings, with respect to other satellites, so that the satellite enters an active orbit segment and initiates transmission of downlink signals as a second satellite exits an active orbit segment and ceases transmission of the downlink signals.
