Publication number: 20110180670Abstract: An In Orbit Transportation & Recovery System (IOSTAR™) (10) is disclosed. One preferred embodiment of the present invention comprises a space tug powered by a nuclear reactor (19). The IOSTAR™ includes a collapsible boom (11) connected at one end to a propellant tank (13) which stores fuel for an electric propulsion system (12). This end of the boom (11) is equipped with docking hardware (14) that is able to grasp and hold a satellite (15) and as a means to refill the tank (13). Radiator panels (16) mounted on the boom (11) dissipate heat from the reactor (19). A radiation shield (20) is situated next to the reactor (19) to protect the satellite payload (15) at the far end of the boom (11). The IOSTAR™ (10) will be capable of accomplishing rendezvous and docking maneuvers which will enable it to move spacecraft between a low Earth parking orbit and positions in higher orbits or to other locations in our Solar System.Type: ApplicationFiled: February 7, 2007Publication date: July 28, 2011Inventors: Robert F.

Patent number: 6157621Abstract: The Satellite Communication System disclosed in the specification is a dynamic constellation (C) of satellites (S). The present invention is capable of offering continuous voice, data and video service to customers across the globe on the land, on the sea, or in the air. The preferred embodiment of the invention comprises a low Earth orbit satellite system that includes 40 spacecraft (S) traveling in each of 21 orbital planes at an altitude of 700 km (435 miles). This relatively large number of satellites employed by the preferred embodiment was selected to provide continuous coverage of the Earth's surface at a high minimum mask angle (1230a) of forty degrees. Each of the individual 840 spacecraft (S) functions as an independent sovereign switch of equal rank which knows the position of its neighbors, and independently handles traffic without ground control.Type: GrantFiled: September 10, 1997Date of Patent: December 5, 2000Assignee: Teledesic LLCInventors: Alison K.

Patent number: 5822680Abstract: A communication system and methods for sharing a common communication frequency, without interfering with a second communication system which has a plurality of satellites operating in geostationary orbits (GO) and ground stations (GS) which communicate with the satellites (GEO) on the common communication frequency, is disclosed. Conventional geostationary satellites broadcast in C and K.sub.u bands. Ground stations (GS) which receive these signals must have their antennas pointed toward the plane of the Equator (EQ). Satellites (10) which occupy inclined orbits (LO) and communicate with terrestrial terminals (12) propagate beams of energy that do not intersect the plane of the Earth's Equator. Terrestrial terminals (12) in the northern hemisphere communicate with a satellite (10) only when the sub-satellite point of the satellite (10) is at a latitude more northerly than the terrestrial terminal (12).Type: GrantFiled: November 7, 1996Date of Patent: October 13, 1998Assignee: Teledesic LLCInventors: James R. Stuart, Mark Alan Sturza, David P. Patterson

Patent number: 5678175Abstract: A satellite communications system is disclosed. One of the embodiments of the present invention includes six to fourteen satellites (12) which operate in a single Equatorial orbit (14). These satellites (12) are capable of providing communications services to locations on the Earth (E) which are within thirty degrees of the Equator (16). Another embodiment of the invention utilizes both the single Equatorial orbit plane (14) in combination with other satellites (12) moving in polar or inclined orbits (60, 63, 210). The embodiment that combines satellites (12) in Equatorial (14), polar (60) and inclined (63, 210) orbits will provide a wide variety of data services to virtually any point on the globe. In the preferred embodiments, the satellites (12) are designed to operate in a circular low Earth orbit at an altitude of from 800 to 1852 kilometers.Type: GrantFiled: June 6, 1995Date of Patent: October 14, 1997Assignee: Leo One IP, L.L.C.Inventors: James R.

Patent number: 5666648Abstract: One of the preferred embodiments of the present invention is a telecommunications system that includes twelve satellites (S) which are equally deployed in four polar low Earth orbits (OR). A preferred embodiment provides a system for transmitting a message between two terminals (G) on the ground through a store-and-forward network. A first satellite (S1/OR1) traveling in a first polar orbit (OR1) receives and stores a message from a sending terminal (GA) on the surface of the Earth (E). As the first satellite (S1/OR1) passes over the North Pole (NP), it transmits the stored message from the sending terminal (GA) down to a relay station (GB) located near the North Pole (NP). The message is stored at this polar relay station (GB) until a second satellite (S1/OR2) moving in a second orbit (OR2) flies within range.Type: GrantFiled: April 18, 1995Date of Patent: September 9, 1997Assignee: Leo One IP, L.L.C.Inventor: James R.

Patent number: 5641135Abstract: A series of spacecraft designs (10, 42 and 52) for a Satellite Communication System is disclosed. One of the preferred embodiments of the invention called "Gearsat.TM." (10) comprises a hollow torus which inflates when it reaches orbit. When viewed from the side along its circumference, Gearsat (10) looks like two flattened pyramids sharing a common base. Phased array antenna panels (14) are deployed across the top of the pyramid along an exterior cylindrical surface (12), while twin arrays of solar cells (16) cover the slanted surfaces. The satellite (10) rotates about its center, and individual antenna panels (14) are spatially synchronized to transmit and receive signals from particular regions on the ground. An alternative embodiment, called "Batsat.TM." (42, 52), includes a central cylindrical body (B) and a plurality of substantially circular linked antenna and solar/thermal panels (A1-A9 and S1 and S2) which carry individual antennas (X) and solar/thermal surfaces (Y).Type: GrantFiled: May 5, 1994Date of Patent: June 24, 1997Assignee: Teledesic CorporationInventors: James R. Stuart, David Palmer Patterson
