摘要： Combinations of antenna types, which may include parabolic reflectors, electronically scanned arrays (ESAs), lens antennas and other directional antenna types enable a satellite ground terminal that is adaptable for use in multiple frequency bands such as C, Q, V, Ku, X and Ka bands, with satellites in various orbital configuration such as LEO, MEO, other non- GEO, and GEO, and in various user scenarios such as fixed, At the Quick Halt (ATQH), or On-the-Move (OTM). The VS AT or MVS AT of the invention does not require alteration or modification to support these multiple uses cases. As a result of this interoperability there are savings in unit cost and logistics. The system and method of the invention allow rapid re- configuration of the ground segment of a satellite communication system to overcome loss of space segment assets, by enabling the inventive ground terminal to quickly transition to communicate with alternative satellites.

摘要： Method for providing multi-input multi-output (MIMO) feeder links for a multibeam satellite system includes configuring a X×Y MIMO antenna system; transmitting, simultaneously, a Tx signal as X Tx signals on a MIMO channel with the X-antennae; receiving the X Tx signals on the MIMO channel with the Y-antennae as Y Rx signals, wherein each of the Y-antennae generate one of the Y Rx signals; and ground-interference processing the X Tx signals or the Y Rx signals to recover the Tx signal; satellite-interference processing the X Tx signals or the Y Rx signals to recover the Tx signal. In the method, the ground interference processing includes countermeasures as either pre-interference processing when the X-antennae are disposed on a ground or post-interference processing when the X-antennae are disposed in a Geosynchronous orbit satellite. Gateway diversity for multiple MIMO feeder links utilizing these countermeasures improves weather-resiliency and significantly enhances overall satellite network availability.

摘要： Disclosed embodiments relate satellites using a Software-Defined Radio ("SDR") system. In one example, a geostationary (GEO) satellite includes an antenna system including multiple antennas, each configured to provide a spot beam having an adjustable throughput for a terrestrial coverage area while the antenna is in an active state and the satellite is in orbit above the Earth, a front-end subsystem communicatively coupled to the antenna system having an input side including an input filter and an analog-to-digital converter, and an output side including an output filter and a digital-to-analog converter, and a software defined radio ("SDR") communicatively coupled to the antenna system via the front-end subsystem. The SDR, in response to a surge modification request, modifies a throughput of each active antenna by increasing or decreasing a share of a satellite power budget allotted to the antenna by deactivating or activating a previously active or previously inactive antenna, respectively.

摘要： A method and apparatus for operating a satellite system including different satellites that may belong to different types of satellite constellations. In some implementations, the satellite system may include a LEO satellite constellation and one or more non-LEO satellite constellations that can be used to increase the forward link capacity of the LEO satellite constellation, for example, by allowing an LEO satellite to offload at least some of its forward link traffic to one of the non-LEO satellites. The user terminals can dynamically switch forward link communications between a LEO satellite and a non-LEO satellite while maintaining a return link connection with the LEO satellite.

摘要： Embodiments provide techniques for dynamic spot beam assignment in a geostationary satellite communications network. For example, a ground processing node in the geostationary satellite network can monitor spot beam coverage area location and can detect a beam drift trigger indicating present drifting of one or more coverage areas. Ground terminals can be identified as serviced by spot beams associated with the drifting coverage area(s) and as experiencing a signal quality impact from the drifting. The ground terminal node can compute an update to a beam assignment map having a reassignment of the identified user terminals from their presently servicing spot beams to another of the spot beams in a manner that seeks to address at least some of the signal quality impact identified as associated with the drifting. Some embodiments further account for load balancing, and/or other factors, and/or can maintain stateful communications between the reassigned user terminals and the geostationary satellite.

摘要： The present disclosure is directed to an inclined geosynchronous orbit satellite system that can efficiently provide continuous communication to multiple geographic regions across the world using satellites in inclined geosynchronous orbital paths having an equatorial crossing and enabling the reuse of frequencies assigned within GSO orbital locations. The inclined orbit satellite system can include multiple inclined orbit satellites that are capable of co-existing with geostationary satellites to provide continuous uninterrupted service.

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： A satellite is linked to a number of gateways by a number of feeder links. When a degraded link is detected among the feeder links, communications are switched from the degraded link to a diversity link shared among the feeder links. In one embodiment, said diversity link is connected to a diversity gateway located outside a service area of the satellite. In another embodiment, the diversity link comprises channels distributed among the feeder links within the service area.
