Gaining a time signal from a radio signal such as GPS, an ultra-wide band constellation can be synchronized. While the entirety of the constellation is synchronized to a nanosecond level of accuracy, local subsets of ultra-wide band nodes can establish even finer degrees of synchronization resulting in more accurate positional determination. These synchronization signals can be propagated to other nodes that are denied or incapable of receiving synchronizing radio (GPS) signals. Moreover, in cases in which a plurality of UPN nodes is unavailable to accurately determine an objects position, available UPN nodes can be combined with GPS pseudo ranges to achieve positional determination.

Coherent radar returns gained from Ultra-Wideband Radars are correlated with features extracted from a georeferenced map to refine positional information and pose of an object. Data collected from one or more UWB Radars and other real time sensors affixed on an object can be processed to identify discrete edges or characteristic returns such as a pole, building or the like. These coherent returns can be correlated with features extracted from a georeferenced map. As the UWB Radar(s) location and orientation with respect to the object is (are) known the precise location and pose of the object on the georeferenced map can be determined by matching features found in the map or imagery with those of the coherent return.

A unified collaboration environment is formed by establishing a local workspace positional frame of reference using a plurality of UWB transceivers. With a frame of reference established a communication link is established between each of the workspaces, and a collaboration module to establish a peer-to-peer network. Data is received from each of the workspaces including the local workspace frame of reference, the set of available assets and workspace behavior (tasks). The collaboration module crafts a unified collaboration environment by transforming the local workspace into a collaborative positional frame of reference. A user, through a user interface, can offer real-time input to a virtualized version of the workspace to augment actions within the workspace environment.

MOBILE LOCALIZATION USING SPARSE TIME-OF-FLIGHT RANGES AND DEAD RECKONING
Mobile localization of an object having an object positional frame of reference using sparse time-of-flight data and dead reckoning can be accomplished by creating a dead reckoning local frame of reference, including an estimation of object position with respect to known locations from one or more Ultra Wide Band transceivers. As the object moves along its path, a determination is made using the dead-reckoning local frame of reference. When the object is within a predetermine range of one or more of the Ultra Wide Band transceivers, a conversation is initiated, and range data between the object and the UWB transceiver(s) is collected. Using multiple conversations to establish accurate range and bearing information, the system updates the objects position based on the collected data.
