1. A method for propagation of dimensional accuracy by a primary Ultra-Wide Band (“
- UWB”
) node among a plurality of UWB nodes wherein the primary UWB node includes a primary location and a primary measure of error associated with the primary location, the method comprisingreceiving from each of the plurality of UWB nodes, node information wherein node information includes a location of each node and a measure of error associated with the location of each node;
forming by the primary UWB node a list of the plurality of UWB nodes wherein the list includes for each node the location of each node and the measure of error associated with the location of each node;
apportioning the primary measure of error of the primary UWB node to a plurality of error sectors;
identifying by the primary UWB node a target error sector from the plurality of error sectors to be minimized;
selecting from the list of the plurality of UWB nodes a target UWB node that can diminish error associated with the target error sector of the primary UWB node;
communicating by the primary UWB node with the target UWB node; and
responsive to successive communication with the target UWB node, revising for the primary node the primary location and the primary measure of error.

Abstract
Recursive constellations of Ultra-Wide Band (“UWB”) transceivers are optimized based on a desired functionality or objective. By structuring transceivers of an UWB network into a plurality of subsets or constellations of UWB nodes each constellation can be optimized for a particular purpose while maintaining connectivity and cohesiveness within the overarching network. Implementations of specific functionality can be applied to Intra-Vehicle, Inter-Vehicle and Vehicle-to-Infrastructure constellations resulting in localized optimizations while maintaining a cohesive and coherent UWB network.
