A transportable ground tower for an aircraft landing system, and methods of assembling and raising the same, are disclosed. The ground tower may include at least lower and upper tower sections configured to be assembled to form a ground tower structure extending substantially vertically from a ground surface in an operational orientation. The lower tower section may have a pivot configured to be pivotally secured to a stationary ground base. The ground tower may also include a stand pivotably secured to one of the plurality of tower sections, which is configured to support an end of the assembled tower structure in an assembly orientation to permit assembly of one or more tower devices to the tower structure.

A lighting tower system is provided. The lighting tower system includes a tower positioned in an upright orientation within a bed of a vehicle. The tower includes a base tube section and an upper tube section. The base and upper tube sections include a common longitudinal axis and are arranged to slide relative to one another in a telescoping relationship to move each tower between a retracted position and a fully extended position. The lighting tower system includes a light assembly coupled to and extending from the upper tube section of the tower. The light assembly is configured to rotate with respect to the common longitudinal axis and to tilt with respect to an axis perpendicular to the common longitudinal axis. The lighting tower system includes a mounting configuration configured to attach and detach the tower to the bed of the vehicle in the upright orientation.

A base flange assembly for a lattice section of a tower includes a foot having an aperture; a leg welded to the foot, an axis defined between a center of the aperture and a center of the leg. An inner gusset is welded to the foot and the leg along the axis; and an outer gusset is welded to the foot and the leg at an angle with respect to the axis.

Methods for constructing/deconstructing an antenna tower are provided. The methods can include engaging a stability assembly between a standard and a tower to maintain tension in a line used to raise/lower the tower. Antenna tower construction/deconstruction stability assemblies are also provided. The assemblies can include a stability assembly extending from the standard and configured to rigidly engage a portion of the antenna tower, the stability assembly being operable to maintain the rigid engagement during transitioning of the tower from a down/erect position to an erect/down position.

A mobile tower for transportation to and rapid deployment at remote sites where the mobile tower can be engaged with the ground, the mobile tower including an extendable and retractable tower secured to a mobile support structure including a frame having a plurality of rapidly deployable outriggers, wherein the tower includes three series of pivotally interconnected tower sections or segments, sections or segments of which engage with segments of each of the other series when the tower is assembled; the mobile tower including a plurality of guy wires secured between the extendable and retractable tower and the respective outriggers to stabilize the tower after the tower is assembled. The guy wires are preferably secured to the extendable and retractable tower at first and second connecting positions that are displaced from one another about an outer perimeter. Methods of deploying the mobile tower are also disclosed.

The present disclosure describes various embodiments of systems, apparatuses, and methods for large-scale processing of weather-related data. For one such system, the system comprises a database of weather-related data providing from at least one weather monitoring station and at least one processor for coordinating a data processing job for processing a set of input weather-related data from the database. Accordingly, the input data comprises sensor data from the at least one weather monitoring station positioned on an open shoreline during a hydrodynamic event, weather model data for the hydrodynamic event, and at least one of air-craft reconnaissance data or satellite reconnaissance data regarding the hydrodynamic event, wherein the at least one processor is configured to assimilate the input data and generate, using machine learning, an improved weather prediction model for the hydrodynamic event. Other systems, apparatuses, and methods are also provided.

Aspects of the present disclosure are directed to a telescopic mast. In some embodiment, the telescopic mast includes at least two telescope members with parallel walls. One of the at least two telescopic members including at least two adjoining telescopic sections, with one of the at least two adjoining telescope sections being thinner than the others of the at least two adjoining telescope sections, so that a telescope section can be passed respectively into and out of a telescope section positioned round it in a telescope member. This telescope section positioned round it can be passed into and out of a further telescope section in a further telescope member. The telescopic mast further including elastic elements/actuators fitted between the adjacent telescopic sections, the elastic elements/actuators equalize and bear the dead weight and the useful load on the telescopic mast.
