Trimble R12i—A New Angle of Productivity

With Trimble ProPoint™ GNSS technology and new Trimble TIP™ tilt compensation

More than 30% better performance in challenging environments*


A precise solution for repeatable results.


Real time error estimates in Trimble Access that empower the surveyor.


Faster convergence means less time spent measuring points in the field.



*In head-to-head testing with the Trimble R10-2 in challenging GNSS environments such as near and among trees, and built environments, the Trimble R12i receiver performed at least 30 percent better across a variety of factors, including time to achieve survey precision levels, position accuracy and measurement reliability.

Trimble R12i features at a glance

Trimble ProPoint GNSS Technology

Superior performance in degraded GNSS conditions, with groundbreaking signal management that leverages the latest developments in GNSS signals and Trimble receiver hardware

Trimble TIP Tilt Compensation Technology

Inertial Measurement Unit (IMU) based tilt compensation for accurate laying out and measuring points without precisely leveling the pole

Trimble CenterPoint RTX® Correction Service

Provides RTK level precision worldwide without the need for a base station or VRS network

Trimble 360 Technology

672 channels with support for all available and future GNSS signals, and improved protection from interference and spoofed signals

Trimble xFill® Technology

Keeps you working in radio and cellular black spots with continuous RTK coverage

Challenging GNSS environments are locations where the receiver has sufficient satellite availability to achieve minimum accuracy requirements, but where the signal may be partly obstructed by and/or reflected off of trees, buildings, and other objects.
