NovAtel SPAN Prepares for Road Ahead

摘要

GNSS positioning is highly accurate and reliable - until satellite signals are disrupted. Hexagon | NovAtel has developed SPAN technology that integrates GNSS positioning with inertial measurements for a three-dimensional understanding of position and orientation. SPAN technology delivers accurate heading, velocity, azimuth, pitch, and roll. NovAtel SPAN-enabled receivers and enclosures are effective across applications, including marine environments to monitor heave movements from waves and autonomous vehicles requiring a higher level of precision and integrity. NovAtel has demonstrated SPAN technology's capa- bilities in a sensor-fusion project alongside Almotive and STMicroelectronics. Leveraging sensors on a moving vehicle - GNSS, inertial measurements, and cameras for visual odometry - allowed the teams to produce promising results for continuous positioning on real roads, in underground parking garages, and through tunnels. NovAtel's PwrPak7-El enclosure was used as a reference system in the project, gathering data to confirm the accuracy of the sensor-fusion solution.
