FJD Trion V10Li RTK System.
1760 channels. Green laser to 80 meters. Starlight camera with video photogrammetry. The tightest RTK accuracy in the lineup — 6 mm + 0.5 ppm — in a 980-gram IP68 package.
The V10Li doesn't compromise. It stacks every advantage: the most GNSS channels on any compact rover, a visible green laser that reaches 8× further than competing models, a starlight-grade dual camera with global shutter for blur-free video photogrammetry, and 30W PD fast charging that gets you back in the field faster. This is the receiver for crews who need the highest possible precision and the most versatile measurement toolkit in one device.

Maximum Precision
More channels. Tighter specs. Longer laser.
The V10Li's 1760-channel engine tracks more satellites on more frequencies than any other compact rover — 352 more channels than 1408-channel competitors. That translates to faster initialization (7 seconds typical), stronger fixes in challenging multipath environments, and tighter RTK accuracy: 6 mm + 0.5 ppm horizontal, significantly better than the industry-standard 8 mm + 1 ppm.
The Class 2M green laser reaches 80 meters — eight times the range of typical 10-meter laser RTKs. And the dual starlight cameras with global shutter deliver blur-free video photogrammetry with 3 cm visual survey accuracy at 2–15 meters. No other receiver at this weight class matches this combination.

Six advantages that no competitor matches.
FEATURE 01
Class 2M Green Laser — 0 to 80 meters.
Visible green laser at 520 nm ± 20 nm with ranging accuracy of ±(5 + 100×10⁻⁶×D) mm.

Frequently Asked
Common questions about the V10Li.
What is the FJD Trion V10Li RTK System?
+
The V10Li is FJD's flagship compact RTK system with 1760 GNSS channels (the most on any compact rover), a Class 2M green laser with 0-80m range, dual 2MP starlight cameras with video photogrammetry, 6mm+0.5ppm RTK accuracy, tilt survey to 60°, and a 1.41-inch true color OLED display — all in a 980g IP68 package with 30W PD fast charging.
What is the green laser used for?
+
The Class 2M green laser (520nm) provides non-contact distance measurement from 0 to 80 meters. Unlike invisible infrared lasers, the green beam is visible in daylight so you always know exactly what you're targeting. Use it for measuring across ditches, under bridges, above ceilings, or anywhere you cannot physically place a pole.
What makes the V10Li camera special?
+
Dual 2MP sensors with starlight-grade 3μm pixel pitch and global shutters (not rolling). This means sharp, blur-free imagery even during video photogrammetry capture. 88° FOV captures wide-angle context. Each image group captures in approximately 30 seconds. Visual survey accuracy is 3cm within 2-15 meters.
How does the V10Li compare to the iRTK5 and V600L?
+
The V10Li has 1760 channels (vs 1408), tighter RTK accuracy (6mm+0.5ppm vs 8mm+1ppm), 80m green laser (vs none on iRTK5, 10m on V600L), and a starlight camera with video photogrammetry (vs none on iRTK5, standard camera on V600L). The iRTK5 offers 24h battery and Hi-Fix continuity. The V600L is lighter (730g vs 980g) with 20h battery and IP68. Choose the V10Li when maximum precision, longest laser range, and best camera quality are the priorities.
What is the battery life and charging speed?
+
7000mAh / 7.4V battery: 15 hours rover, 10 hours base, 25+ hours static. 30W PD fast charging via USB-C charges significantly faster than standard 5V chargers. External 9-28V DC power also supported for base station deployment.
What is the price of the V10Li in Dubai?
+
V10Li pricing depends on configuration, accessory bundle, and quantity. Contact Sicher 3D at sales@sicher-3d.com or +971 50 108 0764 for authorized dealer pricing. Volume discounts available for surveying companies and tenders across UAE and GCC.
