International Classification:

H04B 7/204
H04B 7/19
H04B 7/185

Abstract:

Embodiments provide high-throughput, hub-and-spoke satellite communications with geographically non-overlapping user beams and full frequency reuse. For example, a coverage area of a satellite is segmented into multiple candidate coverage zones, and an associated consumption demand is determined for each candidate coverage zone. Fixed spot beams are assigned to a subset of the candidate coverage zones according to highest associated consumption demands, such that each fixed spot beam corresponds to at least one candidate coverage zone to service an associated beam coverage area that is geographically non-overlapping with beam coverage areas of all other fixed spot beams, and each fixed spot beam is allocated full use of a same spectrum. One or more steerable beams selectively cover lower consumption demand zones.

International Classification:

H04W 24/02
H04B 7/185

Abstract:

The described features generally relate to determining dynamic signal quality criteria for an installation of satellite terminals for communications in a satellite communications system. In particular, the signal quality criteria for an installation may be based on an identified position of the satellite terminal to be installed, and in some examples based on the positions and signal characteristics of neighboring satellite terminals that have already been installed. In some examples, a signal quality map may be generated for a service beam coverage area, based on predetermined transmission characteristics and/or measured transmissions from a number of satellite terminals served by a communications satellite. The generated signal quality map may then be used to determine a signal quality threshold for the installation of a satellite terminal being installed for communications in a satellite communications system.

International Classification:

H01Q 3/08
H01Q 1/28

Abstract:

Systems and methods for aligning a satellite antenna mounted on a mobile platform to the platform. At each of several arbitrary orientations, a first directional vector is determined from the antenna to a satellite. For each orientation, an alias transformation is performed to transform the first vector having coordinates defined with respect to a first reference frame to a second vector having coordinates defined with respect to a second reference frame. A third vector is determined based on the orientation of the antenna after peaking the antenna. A rotation matrix is derived from the collection of second and third vectors. An estimate of the rotational offset of the satellite antenna with respect to the platform is determined based on the rotation matrix. The rotational offset is applied to the attitude of the platform to accurately point the antenna to the satellite.

International Classification:

H04B 7/185
G01S 19/05

Abstract:

The described features generally relate to receiving one or more positioning signals at a satellite terminal during installation of the satellite terminal at a customer premises, and providing position-based access to a satellite communications system based on a satellite terminal installation position determined from the received positioning signals. The determined installation position of the satellite terminal may then be employed for various network access techniques, such as providing access to the satellite communications system, providing position-based content, or restricting content via the satellite communications system based on the determined installation position. In some examples the determined installation position of the satellite terminal may be used to approximate a propagation delay between the satellite terminal and various devices of the satellite communications system, such as a serving satellite and/or a serving gateway, to improve device synchronization and radio frequency spectrum resource utilization.
