The Defense Advanced Research Projects Agency (DARPA) is funding a GPS adaptive antenna array using high temperature superconductor (HTS) technology. This adaptive antenna array is designed to null multiple GPS jammers, while being considerably smaller in size than conventional adaptive arrays. The combination of these two requirements can be satisfied only through the unique properties of thin film HTS antenna elements and circuits.A packaged, ruggedized, multielement HTS based, GPS antenna is due to be delivered by March 2000.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
