Robust positioning and orientation of Septentrio inertial receivers enables various autonomous applications in Korea  

SUM (Smart yoUr Mobility), developer of autonomous driving vehicle control technology is combining several sensors to enable autonomous navigation in a challenging environments like ports and urban areas. After rigorous testing and validation SUM selected Septentrio GNSS/INS receivers for accurate and robust positioning and orientation in their systems. SUM’s control systems are being used in vehicle automation in smart ports, an environment that poses many challenges for GNSS positioning, starting from reflections off metal structures as well as signal blockage by containers or overhead cranes. Septentrio FUSE+ inertial sensor-fusion technology enabled receivers to provide the reliability and availability of position that SUM needs for their autonomous technology.

SUM yard trucks are equipped with Septentrio GNSS/INS technology for autonomous navigation in the challenging environment of today’s ports.

Shipyards are only one example of where SUM’s technology is being used. Their autonomous control systems, with Septentrio AsteRx SBi3 Pro+ receivers inside, is also being used in urban applications.

In Gangneung, Korea tourists and residents can catch a ride at their convenience in a shuttle that drives them to key locations of the city. This shuttle comes and goes fully autonomously on the city roads. While a driver is still required by law as a safety precaution, this is the first step to a more autonomous transport future in Gangneung city.

Autonomous shuttle car uses a control system with a Septentrio GNSS/INS receiver for reliable transportation of tourists and residents of the busy Gangneung city in South Korea.

Compared to other GNSS/INS products, the AsteRx-SBi3 Pro+ ensures high reliability and minimal positional errors, while offering various features. Through extensive testing, we have confirmed the reliability of this product's GNSS in the field, and as a result, it is widely used in SUM's autonomous driving service vehicles.

SUM’s autonomous technology powered by Septentrio’s INS receivers is also used in navigation of autonomous buses in the metropolitan city of Seoul.

Why did SUM choose AsteRx-SBi3 Pro+ for their autonomous control system:

  • Positioning reliability and integrity needed for autonomous navigation in challenging environments: the SUM bus drives at the autonomy level-3 in busy urban areas
  • Sub-centimeter positioning accuracy and sub-degree orientation angle accuracy
  • Web UI and data logging was very helpful during the integration and validation phase
  • Waterproof IP68 receiver housing
