Trimble has partnered with Nissan Motor Company to use Trimble’ RTX network as the positioning source to enhance the capabilities of the ProPILOT Assist 2.0 driver assistance system in Nissan vehicles.
The Trimble RTX network is supported by a globally redundant and resilient infrastructure and is backed by a team of ISO 20,000 certified network engineers and IT specialists, which monitor operations to ensure optimal signal performance and reliability for drivers. Trimble’s RTX positioning technology can provide decimeter-level accuracy in seconds, making it suitable for autonomy applications, including automotive driving.
The ProPILOT 2.0 Assist system enables hands-off driving while cruising in a single lane and when the vehicle approaches a road divide. When the car is passing 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 ProPILOT 2.0 Assist system with Trimble’s RTX network will be initially available on the 2023 Nissan Ariya.

Trimble and Qualcomm Technologies, a subsidiary of Qualcomm Inc., will be working together to produce precise-positioning solutions for select automotive applications.
Trimble will work with Qualcomm Technologies to integrate Trimble’s RTX technology with select Qualcomm Snapdragon Automotive 4G and 5G platforms to deliver a highly accurate positioning solution essential for maintaining absolute in-lane positioning.
The new solution will accelerate the adoption of road-level navigation and emergency services applications, as well as satisfy requirements for developing advanced driver-assistance systems (ADAS) and autonomous driving solutions.
The Snapdragon 4G and 5G automotive platforms feature integrated multi-frequency and multi-constellation high-precision GNSS technology. They also support all major global and regional GNSS satellite constellations including GPS, GLONASS, Galileo, BeiDou, and QZSS, operating concurrently on the L1, L2, and L5 frequency bands, including a precise positioning framework.
The framework ensures consistency in access and use of precise positioning information and incorporates the use of GNSS corrections technology.
Tight integration of GNSS functionality in conjunction with the modem reception of the corrections allows for minimum latencies and optimal performance of the precise-positioning solution from the telematics system and provides automakers with a global location platform to meet the requirements of next-generation vehicles.
Trimble RTX technology provides real-time, multi-constellation GNSS corrections and positioning capable of achieving 2-centimeter horizontal accuracy worldwide, compared to uncorrected GNSS positioning that can be accurate to several meters. The combined solution will provide reliable, consistent, high-accuracy positioning, in a broadcast format, to serve even the most precise requirements of the automotive and transportation industries.
“Trimble’s relationship with Qualcomm Technologies establishes a unique alliance between industry leaders, in which both companies are committed to advancing the development of safer, more capable ADAS,” said John Sprivulis, director of autonomous navigation solutions for Trimble’s advanced positioning division. “Together we will offer a solution to the automotive industry that can help accelerate the adoption of precise GNSS positioning in the connected car and transform the way the world drives.”
“Highly accurate positioning is quickly becoming an important element of connected vehicle solutions to support Vehicle-to-Everything (V2X) and other autonomy applications,” said Lars Boeryd, senior director, product marketing, Qualcomm Technologies. “For this very reason, we are working with Trimble to host the RTX precise positioning software library on our Snapdragon Automotive 4G and 5G platforms to offer a robust end-to-end highly accurate position solution for the automotive industry.”
Evaluation kit. An RTX-enabled Snapdragon evaluation kit (EVK) is expected to be available by early 2020, for use by automotive OEMs, Tier 1 suppliers or other stakeholders considering absolute positioning as part of their autonomy solution.
Trimble has also made Trimble RTX Auto an ASIL and ASPICE compliant RTX software library, available to any OEM or supplier who requires a functional safety certified solution.
