Swiss company, u-blox has signed a deal with the award-winning UK based technology company, Focal Point Positioning, to integrate technology that will improve the accuracy and reliability of GNSS devices. The deal will enhance positioning performance and security for growing applications such as smart cities, location-secure IoT and health and fitness wearables.
Patented Supercorrelation technology from Focal Point solves a critical weakness in GNSS caused by multipath interference. Multipath interference occurs when satellite signals bounce off buildings and landmarks, causing GNSS receivers to provide degraded positioning outputs. The result for users is that the blue dot on their phone or device may be in the wrong place, moving in the wrong direction, or may have a large error ellipse. For autonomous vehicles it could lead to positioning errors that place the vehicle in the wrong lane or worse.
Supercorrelation technology uses software to detect and reject reflected signals, resulting in an improvement in the performance of GNSS devices without the need for additional hardware or applications. Supercorrelation also helps with the detection and rejection of GNSS spoofing signals, an increasing concern for autonomous vehicles, ships, and aviation.
