US: The US Air Force Institute of Technology (AFIT) has signed an agreement with Locata Corporation to develop a new technology for GPS receivers. The agreement aims at evaluating Locata”s patented Vray(TM) switching antenna and new correlator technologies for multipath mitigation in position receivers that run at GPS frequencies.
Undthe Co-operative Research & Development Agreement (CRADA), Locata engineers will provide the knowledge and experience they have gained with the Vray systems. AFIT researchers will first design and build a GPS-frequency multi-element switching antenna prototype that is based on Locata Vray patents, and then AFIT intends to use their GPS receiver and this prototype Vray to demonstrate the feasibility of using Locata technology to improve GPS receiver performance. AFIT also plans to design and test several other GPS-based versions of Locata”s flexible switching antenna array.
