Locata’s VRayTM Antenna Technology – Multipath Mitigation for Indoor Positioning

VRayTM antenna technology developed by the Locata Corporation, is demonstrating unprecedented highaccuracy positioning under extreme multipath conditions especially in indoor environments. This new technology is an extremely flexible and adaptable foundation platform upon which many variations can be built for different uses. It therefore offers a new suite of technology solutions which will allow the entire positioning industry to address the many safety and liability critical applications where a robust positioning capability is emerging as an essential requirement especially indoors and in urban areas. This paper details the latest tests performed with Locata’s first commercial VRay technology antenna and electronics system which is today being integrated by commercial partners into industrial indoor positioning applications. The VRay multipath mitigation performance is quantified and the highaccuracy positioning capabilities in Global Navigation Satellite System (GNSS) difficult environments is demonstrated. These results establish this new capability as a major technological advance which can help revolutionize positioning indoors, in urban canyons, and other difficult environments where GNSS does not work because of multipath and signal obstruction constraints.
