摘要： In general, a constellation of spacecraft is used to broadcast to a particular region with high angles of view in order to reduce blockage or shadowing. A constellation of a plurality of spacecraft is placed in 24-hour orbits having inclination of about 55°, eccentricity of about 0.32, semi-major axis of about 42,000 km, longitude of the ascending node of about 43° East, argument of perigee of about 270°, and longitude of the ground track at maximum latitude of about 7° East. The preferred number of spacecraft ranges from three to six. In a particular application of Digital Audio Broadcast to Europe in some embodiments, the most populous cities are provided with service from no more than about 10° from vertical, and broadcast takes place when the spacecraft are above at least 35° North latitude. The broadcast power is reduced during those portions of the orbit in which the ground track lies in the Southern hemisphere.

摘要： Provided is an improved system and method for implementing a constellation of satellites in inclined elliptical orbits. The satellites are operated during the portion of their orbits near apogee to emulate the characteristics of geostationary satellites. The orbits are configured to form a number of closely spaced repeating ground tracks around the earth. In each ground track the satellites operate only in arcs well above or below the equator to provide a large number of non-geostationary orbital slots that substantially increase global satellite capacity without interfering with the existing geostationary satellite ring. Minimum spacing is maintained between satellites in each active arc and between satellites in the active arcs of adjacent ground tracks to ensure that the satellites in the non-geostationary constellation do not interfere with each other.

摘要： Interference effects between television transmitters for amplitude modulated or digital video and operating on a common allocated channel or frequency is avoided while discrimination is improved by synchronizing carrier signals for a plurality of transmitters. Booster transmitters (20, 20') for correcting coverage anomalies can operate on the same channel or frequency rather than requiring a different channel or frequency presently required in translators; making all allocable channels available for diverse broadcast programming. Discrimination between transmitters operating on the same channel or frequency but with potentially differing programming can be achieved with directional antennas (22, 24). Synchronization of carrier signals is achieved by frequency multiplication of a tone relayed over a satellite (18) or microwave transmission (34) channel by an integral power of two using one or more serially connected full-wave rectifier stages (80, 82, 84) and tuned filters (88).

摘要： A communication satellite system (58) dynamically allocates additional downlink resources on the satellite (11) to selected downlink signals to compensate for signal degradation. A typical cause of such degradation is rain where the downlink station is located. Another cause of such degradation is increased communication traffic or bandwidth demand within a particular region.

摘要： An access material for information communication including a transmitter for establishing a radio frequency link allowing the access terminal to initiate information communication via at least one of a multiplicity of communication channels of a time division multiple access (TDMA) satellite communication system. A data communication channel associated with one of the multiplicity of communication channels is provided for transmitting signaling information over the satellite communication system as a first communication channel. A second communication channel, a voice communication channel, is also associated with the communication channel, thus providing, respectively, first and second modes of communication for voice and signaling information transactions. A memory stores a protocol processing information including a signal protocol assigned to the access terminal via the satellite communication system for transmission by the transmitter using the data communication signaling channel for signaling over the radio frequencycommunication link. Robust signaling may be provided with enhanced information modulation such as binary phase shift keying or dual tone multifrequency digits for keying, enhanced noise and power margins for signaling, or a paging antenna provided with the access terminal of the like for a more robust signaling link.

摘要： There is provided a mechanism for networking satellite and terrestrial networks. It comprises: maintaining subscriber-received power levels of terrestrial network transmissions about one order of magnitude above co-channel satellite transmissions to overcome interference and maintaining subscriber transmissions to terrestrial networks at power levels about one order of magnitude of the below co-channel transmissions to satellite networks to avoid causing interference at the satellite. Such power level maintenance is provided by the network in communication with such subscriber. Moreover, a non-orbiting ('grounded') satellite (311) cooperates as a switching node of both the satellite network and a terrestrial network to relay information between a terrestrial subscriber and the satellite radiotelephone network over a terrestrial network. The terrestrial network and the satellite network may communicate via either the inter-sattellite spectrum (305, 306) or the terrestrial-to-satellite spectrum (343).

摘要： An aircraft based satellite communication (SATCOM) terminal includes a broadband aperture configured to communicate through non-geostationary orbit (NGSO) satellites for broadband communications, a management aperture configured to receive NGSO satellite management information from a geostationary orbit (GSO) satellite, and at least one processor that performs operations. The operations receive the NGSO satellite management information from the GSO satellite, where the NGSO satellite management information indicates positions and associated time of a set of the NGSO satellites. The operations acquire a second communication link with a second NGSO satellite among the set using the NGSO satellite management information during handoff switching from using a first communication link that was previously acquired with a first NGSO satellite to using the second communication link being acquired with the second NGSO satellite. The operations then perform broadband communications through the broadband aperture and the second communication link with the second NGSO satellite. Related ground-based control centers are disclosed.

摘要： This disclosure includes various examples and variations of communications networks that employ a satellite network with a plurality of HEO and/or MEO satellites. Regional data centers may be connected to the satellite via gateways. Edge devices may connect to the network through a plurality of edge micro data centers configured in a mesh network to provide distributed and dynamically allocatable compute and storage resources. Each edge micro data center may include a RAN controller to implement an O-RAN network (e.g., via a 5G Node B cell site) to provide end-user devices direct access to the distributed compute and storage resources of the mesh network of edge micro data centers without intermediary backhaul transport layers. Microwave links or other terrestrial network types may be employed to facilitate the mesh network of edge micro data centers.

摘要： A geosynchronous equatorial orbit (GEO) ground station may concurrently receive at a tracking receiver both a first signal (downlink data) at a first frequency from a GEO satellite and an internally-generated calibration signal at a second frequency.. Based on the calibration signal, the tracking receiver may determine a first phase value for the second frequency, then, from the first phase value, determine a second phase value associated with the first frequency based on a first phase offset between the first frequency and the second frequency according to a set of receiver calibration factors, then generate a phase correction value for signals received at the first frequency without interrupting the downlink data coming from the GEO satellite. Having accurate phasing allows the tracking receiver to report tracking errors correctly to the antenna controller and therefore allow for improved tracking performance.
