Provided is an agile, adaptive, globally deployable online network-centric autonomic supply chain management system that when triggered by a predictive / diagnostic condition management system, without user-maintainer intervention, autonomously authorizes a complete requisitioning cycle of supply chain assets to warfighters with unprecedented criticality of speed. A requisitioning cycle is comprised of: (1) asset issue authorization to a vehicle / requester (2) retrograde [return] of repairable to depot and (3) replenishment [resupply] of drawn inventory. It also autonomically provides global total asset visibility of the asset(s) of interest and a tempo surge-priority ranking with a calm-down functions. The system operates in either default autonomic mode or a user activated semi-autonomic mode. In either mode of operation a requisition cycle is accomplished autonomically by selection of the most affordable transportation that ensures delivery of an asset to a user in accordance with contractually specified time-definite delivery standards. The system's material delivery performance effectiveness percentage rate is archived for billing purposes and monitoring system performance metrics. The system almost eliminates SCM administration personpower requirements. It accelerates the entire logistics supply pipeline, resulting in:—higher annual inventory turn-rates thus permitting inventory levels to be reduced and smaller wartime pack up kits thereby lowering lifetime total operating costs. Smaller pack up kits reduces the logistics footprint and thus the number of cargo aircraft required to deploy a unit.

A steering system for a marine vessel includes one or more steering devices operable to turn a marine vessel; a steering input device arranged to generate a desired turn rate signal; a rate sensor arranged to generate a turn rate signal indicative of vessel turn rate; and a control system configured to receive the vessel and desired turn rate signals and to control the steering device(s) to turn the marine vessel so as to minimise any difference between the signals.

A method includes operating a wheeled vehicle including an articulated suspension system; and articulating the suspension system to skid steer the vehicle. A wheeled vehicle having an articulated suspension system includes a skid steering controller capable of articulating the suspension system to skid steer the vehicle. The skid steering controller may be implemented in software and may, but does not necessarily, include three stages for applying a differential torque, varying the traction of at least one wheel, and finely adjusting the wheel's suspension to approach a critical damped response of the vehicle turning rate with respect to its commanded rate, respectively.

Systems and methods for adaptively steering radar beam patterns for coverage during aircraft turns. The radar sensor system is mechanically or electrically steered to alter the radar sensor's beam pattern in order to adapt the radar sensor's field of view (FOV) to cover the area of anticipated aircraft wingtip trajectory. The anticipated trajectory is derived, for example, from the aircraft groundspeed, acceleration, heading, turn rate, tiller position, attitude, taxi clearance, etc.

A target turning angle calculation part 51 calculates a target turning angle δ on the basis of a steering angle θ and a vehicle speed V. A correction turning angle calculation part 52 calculates a transfer function K(s) which is a second transfer function, depending on the vehicle speed V, by using a difference between a transfer function G(s) which is a first transfer function determined on the basis of the specification of the vehicle and a stationary component G(0) of the transfer function G(s), the first transfer function having as an input a turning angle δ and as an output a yaw rate γ of the vehicle, the second transfer function having as an input a target turning rate δ*′ obtained by temporally differentiating the target turning angle δ* and as an output a correction turning angle δc. The correction turning angle calculation part 52 calculates a correction turning angle δc by multiplying the transfer function K(s) by the target turning rate δ*′. A final target turning angle calculation part 53 inputs thereto the target turning angle δ* from the target turning angle calculation part 51 and the correction turning angle δc from the correction turning angle calculation part 52 and calculates a final target turning angle δd by adding the correction turning angle δc to the target turning angle δ*.
