Patent number: 11955715Abstract: A satellite system can include one or more satellites that orbit the Earth. The one or more satellites may have satellite buses that support antenna arrays. The antenna arrays may include space fed arrays. Each space fed array may have an antenna feed array and an inner array that is coupled to a direct radiating array. The direct radiating array may operate in the same satellite band as the space fed array, or upconversion and downconversion circuitry may be used to communicatively couple a direct radiating array that operates in a different satellite band to the space fed array. The satellites may have peripheral walls with corner fittings that can be selected to provide the satellite bus with particular leg strengths. This can reduce overall mass of the satellites in a payload fairing while accommodating different types of antenna arrays.Type: GrantFiled: May 11, 2022Date of Patent: April 9, 2024Inventors: Chris Cosner, Ying Feria, Raenaurd Turpin, Andre Houle, Richard Aston, Brett Cope, Ricardo Leon

Patent number: 6914557Abstract: A system and method for tracking a user. The system is adapted for use in a wireless communication system and creates a plurality of beams within a coverage area. A first beam is directed at a user in a first microcell and a number of additional beams illuminate microcells immediately adjacent the first microcell. The system is equipped with a mechanism for detecting movement of the user from the first microcell to one of the immediately adjacent microcells. On the detection of movement of the user, the system redirects the first beam from the first microcell to a second microcell, the second microcell being one of the adjacent microcells. In the illustrative embodiment, the system is implemented in a stratospheric platform based communication system including a hub adapted to communicate with a stratospheric platform. A transceiver and a phased array antenna are disposed on the platform to communicate with the hub and with the user. A second antenna is provided on the platform to communicate with the hub.Type: GrantFiled: September 5, 2001Date of Patent: July 5, 2005Assignee: The DIRECTV Group, Inc.Inventors: Donald C. D.

Publication number: 20050032545Abstract: A method and system for communicating includes a plurality of cells having base units therein. Each of the base units communicates with a plurality of users within the cells. A communications platform is located in a stratospheric location for transmitting and receiving information with respect to the base units. A gateway station communicates with the communications platform and routes signals to terrestrial networks or other user back through the communications platform. A microcell within at least one of the cells is used to provide coverage in a small geographic area such as within a building. Each of the microcells is also in communication with the gateway station through the platform.Type: ApplicationFiled: September 1, 2004Publication date: February 10, 2005Inventors: Donald Chang, Ming Chang, Ying Feria, Harold Rosen
