No matter what you farm, Trimble has a correction service solution to meet your precision agriculture needs for land preparation, planting, nutrient & pest management, tilling and harvest.

Achieve greater accuracy and work efficiency in the field for all your positioning requirements including: design and stakeout, topographic surveys, right of way and boundary determination, project control, photogrammetric ground control, asset inventory, monitoring, GNSS surveying and mobile mapping.

Trimble correction services offer a range of accuracies from sub meter to centimeter level for mapping requirements across a variety of industries including: public safety, energy transmission, enviromental, government, utilities and more.

Trimble correction services are hard at work too, offering decimeter and centimeter-level accuracy for all your construction and site positioning applications including: site surveys, site stakeout, as-builts and machine control.

Manage and maintain your entire land administration project from conception to completion with Trimble correction services ideally suited for: Cadastral and boundary surveying, mapping and land registration tasks.

Trimble offers correction services ideal for improving safety for personnel on the ground and in the cab with precision positioning for: topographic surveys, slope stability monitoring, photogrammetric ground control and asset inventory.

Trimble satellite-delivered correction services offer an unparalleled solution for high accuracy requirements in remote locations for use in pipeline and land seismic operations in particular. 

Trimble corrections services applications span an even wider range of industries for both civilian and defense work including: aerial sensor systems, unmanned aircraft systems, inertial, rail and more.

High Accuracy, < 4 cm (1.5")

Connect. Correct. Measure. Obtain instant access to real-time kinematic (RTK) corrections utilizing a network of permanent (fixed) continuously operating reference stations while saving time, money and resources.

CenterPoint RTX, Trimble RTX's premier correction service, provides accuracy better than 4 cm (1.5") via satellite or cellular. No other satellite delivered correction service performs better.

Trimble xFill, powered by Trimble RTX technology, augments standard RTK methods by providing instant, seamless back-up corrections for RTK and VRS services during correction stream outages.

Mid Accuracy, < 20 cm (8")

Affordable, decimeter-level correction service built on Trimble's exclusive RTX technology, delivering repeatable accuracy worldwide.

OmniSTAR HP service is the most accurate solution available in the OmniSTAR portfolio of correction solutions. The expected accuracy of OmniSTAR HP is 5 cm.

OmniSTAR XP is a worldwide dual frequency high accuracy solution. OmniSTAR XP service provides long term repeatability of better than 6-10 cm.

OmniSTAR G2 represents the most recent advancement in OmniSTAR subscription service offerings. It is a worldwide dual frequency, providing 8-10 cm high-accuracy solution which uses orbit and clock correction data. OmniSTAR G2 includes GLONASS which significantly increases the number of satellites available.

Broad Accuracy, < 50 cm (20")

Broad accuracy correction service built on Trimble's exclusive RTX technology, providing < 50 cm repeatable accuracy via satellite or cellular delivery worldwide. Agriculture customers can achieve 15 cm (6") pass to pass accuracy.

Entry-Level Accuracy, < 1 m

Affordable, entry-level correction service built on Trimble's exclusive RTX technology, delivering sub-meter, repeatable accuracy worldwide.

OmniSTAR VBS is a sub-meter correction service for users desiring a quick start up time and do not require the highest level of accuracy or repeatability.


Trimble RTX (Real Time eXtended) is a high-accuracy GNSS correction technology delivering repeatable centimeter level positions worldwide. Combining real-time data with innovative positioning and compression algorithms, Trimble RTX utilizes an established global reference station network along with satellite orbit and clock information to compute high accuracy positions. The real-time technology is available via satellite or IP/cellular delivery across most of the world.

Trimble VRS Now provides instant access to real-time kinematic (RTK) corrections utilizing a network of permanent (fixed) continuously operating reference stations.

Trimble xFill, powered by Trimble RTX technology, augments standard RTK methods by providing instant, seamless back-up correction for RTK and VRS services during correction stream outages.

The OmniSTAR services deliver reliable, accurate GNSS positions that help our customers reduce cost and increase productivity.
