摘要： Novel tools and techniques are provided for implementing antenna alignment, and, more particularly, to methods, systems, and apparatuses for implementing antenna alignment using a gimbal. In various embodiments, a gimbal system might be provided. The gimbal system may be at least one of a passive two-axis gimbal, a passive three-axis gimbal, an active two-axis gimbal, and/or an active three-axis gimbal. At least one antenna may be coupled to the gimbal system. The gimbal system may be configured to compensate for at least one of a movement of a structure and/or a wind load on the at least one antenna. Additionally and/or alternatively, the gimbal system may be configured to align the antenna toward the position and orientation where there is the signal quality is optimized.

摘要： The present invention regards a platform and elevation support arrangement (1) and a method for manufacture thereof. An elevation support (3) is to be hingedly mounted to a platform (5) around a first axis (X1) extending along a first direction (B1) via a hinge member (7) arranged between the platform (5) and the elevation support (3); and wherein the elevation support (3) is configured to be locked to the platform (5) in a fixed position by means of an adjustable locking mechanism (9), comprising a first and a second opening (11′, 11″) arranged at a first distance (D1) from each other and comprising a first and second sliding shaft element (13′, 13″) arranged at a second distance (D2) from each other each configured to slide along a second direction (B2) perpendicular to the first axis (X1). The method comprises the steps of providing the platform (5), the elevation support (3) and the adjustable locking mechanism (9); mounting the elevation support (3) to the platform (5); adjusting the adjustable locking mechanism (9) so that the first distance (D1) corresponds with the second distance (D2); and locking the adjustable locking mechanism (9) by sliding the first shaft element (13′) into the first opening (11′) and by sliding the second shaft element (13″) into the second opening (11″).

摘要： A multiple-antenna positioning system with a single drive element, providing reduced weight and complexity over systems that have a drive element for each antenna. In certain examples, each antenna can be coupled with a rotating spindle, with each antenna spindle being coupled with a pair of link arms. By driving a single drive spindle, each of the antenna spindles in the system can be rotated by the associated pair of link arms. The link arms can have an adjustable length, such as through a turnbuckle mechanism, to reduce backlash in the system, and in some examples can apply a preload to the system. By reducing backlash, the multiple antenna positioning system can have improved responsiveness to a rotation of the single drive element, as well as improved stability of the positioning of each antenna when the drive element is held in a fixed position.

摘要： A method for upgrading a dual-band antenna assembly to a tri-band antenna assembly is provided. The dual-band antenna assembly includes a main reflector, and first and second antenna feeds arranged in a coaxial relationship and directed toward the main reflector. The first and second antenna feeds are for first and second frequency bands, respectively. The method includes positioning a third antenna feed through a medial opening in a center of the main reflector, with the third antenna feed directed towards the first and second antenna feeds. The third antenna feed is for a third frequency band. A subreflector is positioned between the main reflector and the first and second antenna feeds. The subreflector includes a frequency selective surface (FSS) material that is reflective for the third frequency band and transmissive for both the first and second frequency bands.

摘要： Systems and methods are described for supporting dynamic antenna platform offset calibration for an antenna system mounted to a mobile vehicle. In particular, dynamic antenna platform offset calibration can be performed while communicating user data associated with the mobile vehicle (e.g., based at least in part on alignment calibration procedures including measurements of user data signals), with an antenna platform offset being updated when alignment calibration procedures have been performed at suitably separated spatial conditions. Accordingly, antenna platform offset calibration may be performed throughout the operation of the mobile vehicle without requiring that the vehicle be proactively aligned in a particular orientation for a dedicated calibration routine prior to using the antenna for communicating user data during normal operation of the mobile vehicle.

摘要： An antenna system for an unmanned aerial vehicle (UAV) includes an antenna having a transmit-receive radiation pattern with a peak strength in a first direction of the antenna, a first strength reducing to a first predetermined strength below the peak strength at a first angle away from the first direction, a second strength reducing to a second predetermined strength lower than the first predetermined strength at a second angle greater than the first angle away from the first direction, and a third strength reducing to a third predetermined strength lower than the second predetermined strength at angles greater than the second angle away from the from the first direction. The antenna system further includes a self-leveling antenna mount to maintain the first direction in substantial alignment with a straight downward direction relative to the UAV despite a change in roll, pitch, or bank of the UAV.
