GNSS/INS is a technology that enables autonomous vehicles to navigate in challenging environments.

Septentrio is a leading global manufacturer of GNSS receivers specialising in high-precision positioning solutions. The company's AsteRx SBi3 Pro+ is a high-performance GNSS/INS receiver that combines advanced GNSS technology with an Inertial Measurement Unit (IMU) for precise positioning and orientation in a variety of environments. This receiver has been designed with durability and reliability in harsh conditions in mind, making it ideal for autonomous vehicle control technology.

SUM, a developer of self-driving vehicle control technology, chose Septentrio's AsteRx SBi3 Pro+ receiver to ensure that its self-driving system achieves accurate and robust positioning and orientation in challenging environments such as harbours and urban areas. These environments present a number of challenges for GNSS positioning, such as reflections from metal structures and signal blocking, and the advanced features of the AsteRx SBi3 Pro+, such as Septentrio FUSE+ inertial sensor fusion technology, provide the required positional reliability and availability.

SUM has used this technology in a self-driving shuttle bus service in Gangneung, South Korea, which operates on city roads to provide convenient transport for tourists and residents.SUM's technology has also been used for autonomous bus navigation in the metropolitan city of Seoul, demonstrating the effectiveness of Septentrio receivers in real-world autonomous driving applications.

The AsteRx SBi3 Pro+ receiver's sub-centimetre positioning accuracy and sub-degree orientation angle accuracy, as well as its rugged IP68 waterproof enclosure, which allows it to operate stably in harsh port environments, demonstrate Septentrio's expertise in designing high-precision GNSS receivers that can withstand extreme conditions.

As autonomous driving technology evolves, Septentrio's AsteRx SBi3 Pro+ receivers will continue to play a key role in driving this change, especially in applications that require high-precision and high-reliability positioning. The South Korean government's aggressive planning in the field of automated driving and rapid development in the automated driving industry chain demonstrate the potential impact of Septentrio's technology in the global automated driving revolution. OEMs and suppliers should consider adopting Septentrio's advanced technology when formulating their autonomous driving strategies to ensure they remain competitive in the upcoming era of autonomous driving.
