The system combines Trimble RTX corrections with the ProPoint Go positioning engine to create a resilient sensor fusion platform for the Lucid Gravity. By fusing satellite signals with data from 6 axis inertial sensors, the vehicle maintains a continuous and precise estimate of its lane and position, even during brief outages or degraded satellite visibility.
Standard automotive navigation often exhibits positional error on the order of meters, which can be insufficient for lane identification and for advanced driver assistance functions. Trimble reports that its integrated solution can reduce this error to a few centimeters, allowing the vehicle to confirm which lane it occupies and to support higher confidence in automated assistance features.
"This collaboration marks a major shift in how vehicles perceive the world," said Olivier Casabianca, vice president, advanced positioning at Trimble. "The Lucid Gravity is the first electric vehicle to fully integrate Trimble's sensor fusion engine. We aren't just helping the car find the road; we are enabling it to drive with resilience and reliability in the most challenging environments on earth."
Trimble states that the positioning stack operates in the background of the Lucid Gravity to support several driver facing functions. As the primary source of location, velocity and heading, it reduces the "searching for signal" lag that drivers can experience in urban canyon environments, helping to maintain continuous route guidance.
High accuracy geolocation information from the Trimble engine feeds directly into the Lucid Hands Free Driving Assist system. This allows the assist feature to place the vehicle more precisely on the highway, which can support smoother lane centering and more consistent automation performance.
The platform also supplies precise altitude data, which Lucid uses to refine battery range estimates against real world gradients and terrain. Trimble indicates that this altitude aware approach can give drivers a more accurate view of remaining mileage, since climbs and descents are directly factored into energy calculations.
Lane level positioning data from the Trimble solution is intended to unlock new infotainment and application capabilities inside the Lucid Gravity. Developers can use the location fidelity to build services and dashboard experiences that respond to exact lane placement, rather than only to general road position. For fleet operators using Lucid Gravity vehicles, the same high fidelity data can support more precise tracking and management of assets. With centimeter level positioning, back end systems can monitor route adherence, stop locations and operational behavior more accurately than with conventional GPS alone.
Trimble notes that the positioning suite will be standard equipment on new Lucid Gravity vehicles starting at the end of January 2026. Vehicles already in service will obtain the capabilities through an over the air software update, adding the new positioning intelligence without requiring a hardware retrofit.
