Abstract
We are developing integrated ultra-wideband transceivers, called Localizers, for precise position location and low datarate communication. Localizers determine location by sharing range information within a network of units distributed in the environment. The range between pairs of Localizers is determined by cooperatively exchanging ultra-wideband signals consisting of coded sequences of impulses. As Localizers are activated, each acquires as many contacts as possible. As local groups of nodes form into clusters, nodes in one cluster link with one or more nodes in other clusters, forming bridges between the clusters. Range information is constantly shared so that all Localizers are aware of all other Localizers in the network. Using precise timing techniques, the Localizers are able to establish these ranges to an accuracy of about a centimeter. The Localizer system has been under development for the last eleven years. Currently, it is being applied to the identification and location of assets at naval storage and shipping facilities. Under this, and other development projects sponsored by the DoD, the device is now reaching the demonstration stage. We plan to apply our Localizer technology and expertise to research RF Time of Flight Ranging Techniques for Self-Localization of Microsensors.
