GNSS RTK RECEIVERS
Choose T40 for a visualized laser point-measurement workflow, or T40Pro for image-based surveying. Both offer GNSS RTK, IMU tilt measurement, AR stakeout and two removable batteries that support hot-swapping.
THE PRACTICAL DIFFERENCES
Start with T40 when your procedure calls for aiming at a visible target and measuring a point with a laser. Check the target surface, visibility, working distance and required accuracy before selecting this workflow.
Start with T40Pro when you want a photogrammetric workflow for extracting point coordinates from captured images. Confirm the image-capture procedure, compatible controller and field software for your project.

|---|---|---|
| Primary extra measurement workflow | Visualized laser point measurement with a laser-assist camera | Photogrammetry / image-based survey |

Laser module range, laser 3D measurement error, photogrammetric error and GNSS RTK accuracy describe different measurements. Keep the stated method and distance with each figure; they do not provide a direct accuracy ranking. The published operating time applies to controller network mode and depends on field conditions. Both weight figures exclude batteries. Confirm the quoted kit, software compatibility and destination-market configuration before ordering.
Specifications checked against the following product documents on 3 November 2026.
COMPLETE YOUR CONFIGURATION
For CORS / NTRIP, confirm service coverage, credentials, mobile connectivity and coordinates. For a local base, specify the base receiver, radio protocol, antenna and power supply.
Plan an RTK + CORS/VRS configuration →Include the receiver quantity, controller, field-software licence, pole, radio, charger, batteries and case. Share any equipment you already own so compatibility can be reviewed.
Review product tests and workflows →SELECTION QUESTIONS
T40 focuses on visualized laser point measurement, while T40Pro focuses on photogrammetry and image-based surveying. Their linked datasheets list the same GNSS channel count, body dimensions, weight without batteries and dual removable-battery arrangement.
The linked datasheets give the same GNSS RTK RMS figures for both: horizontal ±(8 mm + 1 ppm) and vertical ±(15 mm + 1 ppm). The key selection difference is the extra measurement workflow. Laser and image-survey accuracy statements apply to different methods and distances.
No. The 30 m figure is the laser module range; the separate 3D error statement of no more than 2.5 cm applies within 5 m. Review the target and site conditions against the appropriate specification.
Yes. Both datasheets describe two removable 7.2 V, 3400 mAh batteries and support for hot-swapping. Include the charging cradle and any spare batteries in the equipment plan, and follow the model-specific operating instructions.
Yes. Both datasheets list IMU tilt measurement and AR stakeout. Confirm the controller, software version, enabled functions and project coordinate setup in the proposed field kit.
Send your country, task, typical point conditions, required measurement method and correction source. Include the receiver quantity and any controller, field software, base receiver or radio you already use, so the complete configuration can be checked.
