Swift Navigation precise positioning technology improves GNSS receiver accuracy

November 16, 2020  - By

Swift Navigation announced its precise positioning platform can improve the performance of existing single-frequency GNSS positioning, found on most production vehicles today, from the standard average of 3 meters to lane-level accuracy without changing existing hardware and antenna.

According to Swift, these findings are demonstrated during the regular test drives the Swift team conducts to confirm the efficacy of its solutions and software updates. The graph depicts the improved positioning accuracy and availability when a single-frequency receiver is used with corrections from the Skylark precise positioning service and the Starling positioning engine, Swift said. A performance improvement from 2 meters to 0.7 meters for 95% of this mixed-environment drive was achieved on a production vehicle with a low-cost automotive receiver and antenna.

Skylark, Swift’s wide area, cloud-based GNSS corrections service delivers real-time, high-precision positioning, is hardware-independent and is most accurate and seamless when integrated with Starling as a complete solution. Starling is a high-precision positioning engine that works with a variety of automotive-grade GNSS chipsets and inertial sensors, making it ideal for autonomous, ADAS (advanced driver assistance systems), V2X (vehicle-to-everything) and navigation applications, Swift added. Starling is platform-independent and also enhances the measurements for commercially available GNSS receivers.

“Swift is excited to share these findings with the public,” said Joel Gibson, executive vice president of automotive at Swift. “The ability to provide higher accuracy to programs without requiring hardware changes can be a game changer for cost-sensitive programs and brings immediate visible benefit to navigation systems, V2X and many other applications.”
