XGRIDS K1 RTK Module

XGRIDS K1 RTK Geopositioning Module: scanning large areas with ground binding

The XGRIDS K1 RTK Module is an addition to the basic XGRIDS Lixel K1 model (or "Lixel Kity K1"), which adds the RTK (Real-Time Kinematic) geopositioning function. Thanks to this, during scanning, coordinates are obtained in a global system with high accuracy, minimizing the need for significant post-processing, control points, etc.

Main features of the XGRIDS K1 3D scanner and its RTK module

Features of the XGRIDS K1 scanner

• Base device: the Lixel K1 scanner has 40 LiDAR laser channels, a scanning speed of ~200,000 points/s.
• Camera resolution: 2 × 48 MP panoramic cameras that provide high-quality color images for coloring in the point cloud.
• LiDAR operating range: up to ~40 m for the base model (from 0.1 m to ~40 m) with appropriate point quality.
• Weight and portability: the scanner itself with the battery weighs ≈1 kg.
• Absolute accuracy: with the RTK module, it is possible to obtain coordinates with an accuracy of ~3 cm (absolute accuracy).
• Relative accuracy: about ±1.2 cm in standard LiDAR mode without RTK.
• Operating temperature range: from -20 °C to +50 °C.
• Operating time: about 1.5 hours on a single charge of the standard battery.
• Protection: the body has an IP54 rating.

Features of the RTK module for K1

• The module allows you to get absolute coordinates during scanning 3D without the need for a significant number of Ground Control Points (GCP).
• It has status indicators: an LED or other signals that show whether the RTK module is connected, whether a "fixed" solution has been obtained, or whether the signal is "float" or "inaccurate."
• It supports working with various RTK formats / correction sources: "Custom," "Qianxun SI," "China Mobile," and others, depending on the region and signal provider.
• The RTK module integrates hardware and software with K1, used in conjunction with the LixelGO application for setup, signal control, and status.

Where and for what tasks the RTK module for XGRIDS K1 is used

• Geodesy and cartography: when accurate absolute geopositioning of buildings, plot boundaries, profiles, and terrain is required.
• Engineering infrastructure: control of bridges, structures, communication lines, pipelines, when an error in positioning will lead to undesirable consequences.
• Construction and BIM modeling: formation of volumetric 3D models, digital twins with accurate binding to coordinate systems.
• Architecture and protection of cultural heritage: 3D scanning of facades, interiors, historical objects, when the accuracy of position is important.
• Monitoring of the environment and landscapes: changes in terrain, erosion, control of humidity/changes in vegetation, anthropogenic influences.

Advantages for users of the K1 RTK module

Significant reduction in post-processing time — fewer correction points, fewer alignments and manual work.

Reduction of absolute positioning errors — project plans, maps, and BIM objects are immediately in the coordinate system without major shifts.

Increased data reliability — when the RTK signal has a "fixed" status, the point cloud will have high accuracy and less noise.

The ability to work on a large scale: on streets, in open spaces, in areas where there is an access point for RTK corrections, without the need for a large amount of ground preparation.

Improved model quality: better geometry, better integration of color and LiDAR points, fewer distortions, especially at the edges of the scan.

1. Limitations: when the use of the XGRIDS K1 RTK module does not bring significant improvements
2. If scanning is performed indoors or in places without an RTK signal, the module will not be able to get a "fixed" solution, and the accuracy of absolute positioning will decrease.
3. If the task allows a larger error, for example, ±5-10 cm, or if the content of the work is only to create relative models without rigid external coordinates, the cost of the module may be excessive.
4. If needed, I can provide a comparison of the K1 without RTK vs with RTK with numbers (accuracy, time, cost) — this can help the user make a decision.
