    Abstract: A system and method for providing media access control for networked nodes over a plurality of channels. Each channel is divided into a number of time slots per frame of data organized in a channel allocation schedule. The number of time slots is selected for each channel and is greater than or equal to one per second. Each time slot has a slot transfer rate equal to or less than the maximum channel transfer rate. A server receives a request for channel resources that includes a bandwidth requirement. At least one time slot in a channel corresponding to the bandwidth requirement over a frame time is identified and sent to the requesting node.

    Abstract: Systems, methods, and computer-readable media storing instructions for determining cross-track error of an aircraft on a taxiway are disclosed herein. The disclosed techniques capture electronic images of a portion of the taxiway using cameras or other electronic imaging devices mounted on the aircraft, pre-process the electronic images to generate regularized image data, apply a trained multichannel neural network model to the regularized image data to generate a preliminary estimate of cross-track error relative to the centerline of the taxiway, and post-process the preliminary estimate to generate an estimate of cross-track error of the aircraft. Further embodiments adjust a GPS-based location estimate of the aircraft using the estimate of cross-track error or adjust the heading of the aircraft based upon the estimate of cross-track error.
