Nissan has partnered with Trimble to use Trimble RTX® technology for high-accuracy positioning in its ProPILOT Assist 2.0 driver assistance system. This technology will be utilized in the 2023 Nissan Ariya, allowing for hands-off and guided freeway driving capabilities.
While standard Global Navigation Satellite System (GNSS) signals can drift up to 10 meters (25 feet), Trimble RTX technology provides higher accuracy, resulting in consistent lane determination for driving applications. Lane-level accuracy is a key enabler for advanced driver assistance systems (ADAS) and is increasingly used on freeways as we move towards fully autonomous solutions.

Trimble has been a leader in precise positioning for decades and has served the automotive segment for nearly as long. Trimble’s technology leadership, combined with its domain experience, has enabled the company to provide more than 30 million miles of confident driving with hands-off driving systems. Patricia Boothe, General Manager of On-Road Autonomy at Trimble, emphasizes the company’s commitment to providing high-quality, reliable technology.
The ProPILOT Assist 2.0 system enables hands-off driving while cruising in a single lane. As the vehicle approaches a road divide or an opportunity to pass a slower vehicle, the system judges the appropriate timing of branching off or passing based on information from the navigation system and 360-degree sensing. The driver receives intuitive audio and visual guidance and is prompted to put both hands on the steering wheel and confirm the operations.

Trimble’s positioning solution, which includes integrity monitoring capabilities, enables consistent lane-level positioning in complex, real-world driving environments. The driver must remain alert and attentive at all times, as with any current steering system.
Trimble’s RTX positioning technology provides decimeter-level accuracy in seconds, making it an ideal solution for autonomy applications, including automotive driving. The technology’s speed of convergence, accuracy, and accessibility to a single global network make it a reliable choice. The Trimble RTX network is monitored 24/7 by a team of ISO 20000 certified network engineers and IT specialists, ensuring optimal signal performance and reliability for drivers who rely on it.
