XGRIDS K1 RTK Module – Satellite positioning module

RTK Module for Satellite Positioning for XGRIDS K1

The RTK (Real-Time Kinematic) module for the XGRIDS Lixel K1 3D scanner is an add-on that provides high-precision real-time satellite positioning. It allows you to link 3D point clouds not just to the initial scanner position (SLAM), but to a global coordinate system, which is especially important for tasks in topography, geodesy, cadastre, or construction control.

Specifications

• Absolute accuracy: up to ~3 cm.
• Relative accuracy (between points in one scan): approximately 1.2 cm.
• Repeatability:around 2 cm.
• Supported satellite systems:GPS (L1/L2/L5), GLONASS (L1/L2), BDS (B1/B2/B3), Galileo (E1/E5a/E5b/E6b).
• Operating conditions / requirements:mainly outdoor spaces where the RTK signal is stable. In case of a weak signal or in enclosed spaces, the module may not be able to provide a fixed solution.
• Status indication device:LED indicator (red, blue, green):
• red - RTK not connected;
• blue -  connected, but "unfixed" solution;
• green - stable, "fixed" solution.
• Compatibility:works with XGRIDS / Lixel K1 (handheld portable LiDAR scanner) and the corresponding software (LixelGO, LixelStudio).
• Weight and dimensions:gross ~0.170 kg, net ~0.110 kg.
• Mounting:features a quick and reliable attachment to the scanner body, no complex tools required.

Advantages of using the RTK module with the XGRIDS K1 3D scanner

• Geo-referencing "from the field" — the point cloud is immediately provided with coordinates in the global system, eliminating the need for lengthy post-processing or manual calibration during stitching.
• Improved accuracy — thanks to RTK, an absolute error of about 3 cm is achieved, which is critical for a number of tasks (engineering, monitoring, cadastre).
• Time reduction — processes that usually take significant time after scanning can now be significantly accelerated or minimized.
• Increased reliability — when SLAM tracking loses stability (e.g., in difficult terrain, between buildings, in a forest), the RTK module helps maintain accuracy and referencing.
• Wide range of applications — from architecture and construction to cartography, agriculture, archaeology, cultural heritage, VR/AR models, and digital twins.
• Scalability and compatibility — the module easily integrates into the existing K1 system, uses the same software (LixelGO, LixelStudio), and supports different coordinate systems.

Using RTK XGRIDS in various fields

• Geodesy, cadastre:for precise topographic surveys, boundary determination, especially when legal and technical data reliability is required.
• Construction / infrastructure control:monitoring of deformations, checking the condition of foundations, roads, engineering utilities — at least geo-referencing + high accuracy.
• Architecture, digital twins:when models of buildings, cultural objects must precisely align in space, for BIM, VR, visualization.
• Agriculture, forestry, land management:calculation of areas, volumes, location of objects on large territories — centimeter errors can lead to noticeable mistakes.
• Archaeology, cultural heritage:details, characteristic features of the terrain, location of artifacts — everything important in a historical context requires precise position specification.

How the module improves the 3D scanning process

• Installation:is added to the scanner body by connecting via a bracket, fixed without tools.
• Startup and setup:the RTK mode is activated via the LixelGO app, NTRIP settings are entered, or a provider is selected, and you wait for a fixed solution.
• Scanning:in RTK mode,scanning 3D is performed as usual, but each point cloud receives geographic referencing "on the fly."
• Processing:points with coordinates are imported into LixelStudio; there is no need to manually align or correct positioning.
