New GNSS correction technology enables instant lane-level accuracy

Hexagon’s positioning intelligence division has recently demonstrated the TerraStar X, a Global Navigation Satellite System (GNSS) correction technology, which enables instant lane-level accuracy, ideal for autonomous automotive planning programs. In partnership with Ligado Networks, they have demonstrated delivery of TerraStar X technology over both satellite and cellular networks to position vehicles with 5-centimetre (2-inch) accuracy in under a minute. Combining TerraStar X technology with multiple delivery channels is a significant step towards the future of Autonomous X, where cars, UAVs, industrial vehicles, trains, and more will operate safely, securely, reliably, and efficiently.

 

TerraStar X technology is a breakthrough in GNSS. Built on the latest Precise Point Positioning (PPP) algorithms, it leverages the existing Hexagon capabilities in ground network infrastructure, correction data generation, and data packaging for delivery. By eliminating convergence time while providing high accuracy global positioning, TerraStar X will form the future of Hexagon’s correction services for safety of life applications and Autonomous X. When combined with automotive-grade GNSS receivers available through Hexagon Positioning Intelligence, this technology allows automotive customers to evaluate positioning performance in real-time using data delivered over the cellular network or the L-band frequency using Ligado’s SkyTerra satellite in North America.

Trial networks for customer evaluation are currently available in California, Arizona, and Michigan over satellite or cellular network, and in Germany using cellular delivery. The infrastructure is scalable, enabling timely geographic expansion to accommodate automotive development programs globally. Commercial solutions designed uniquely for the automotive market will be available in 2019.
