Spirent Communications plc announced the launch of Spirent GNSS Foresight, an innovative cloud-based solution that lets operators know in advance where and when GPS or GNSS positioning is reliable for unmanned and autonomous journeys. GNSS Foresight accurately predicts where and when unmanned vehicles, air taxis, and drones can operate safely and dependably beyond visual line of sight (BVLOS), especially in urban areas where buildings frequently obstruct GNSS signals. The service is the first of its kind and addresses one of the key issues facing developers and operators of unmanned aerial (UAS) and autonomous vehicles. Because GNSS performance can be unpredictable in urban and suburban areas due to signals being obscured or blocked by buildings, autonomous systems have not been able to rely on GNSS for accurate positioning.
