XGRIDS Pro Guide™ / Module 2: Hardware Setup

2.3 Hardware Overview

Three current devices, two output types, one ecosystem. Specifications, capabilities, and honest differences.

GPSSupported (approximate geolocation only)

Output3DGS only

Field appLCC Scan

Cannot produce point clouds. Processes through LCC Studio only. The macro camera captures fine detail at 0.27 to 0.55 m depth of field.

Coordinate system constraint. The K2 supports WGS84 and CGCS2000 only. The L2 Pro supports broader datums through LixelStudio post-processing. If your project requires native NAD83, NAD27, or another regional datum at the point of capture, use the L2 Pro. Coordinate conversion from WGS84 in post-processing is possible but adds transformation steps.

Map Fusion requires matching L2 Pro models. A 16-channel scan cannot be fused with a 32-channel scan. Confirm model configuration before combining sessions.

Section 3

Use Cases by Device

L2 Pro

Campus and Large-Scale Projects

Multi-building sites, mixed indoor/outdoor environments, and projects where geometry exists at significant distances from the scanner. Covers tens of thousands of square meters per battery.

Multi-building campus documentation
Large commercial interiors and warehouses
Mixed indoor/outdoor on a single scan route
RTK or PPK georeferencing projects
Drone-mounted scanning (DJI M350 RTK and M300 RTK)
Tunnels and degraded environments (32-300 model)

Lightweight Indoor and Small-to-Medium Outdoor

Single-building and dense interior scanning, surveying and topographic mapping, BIM data capture and verification. K2's built-in RTK (UM980) and real-time colorized point cloud reduce on-site verification time and remove the need for an external RTK module. Covers most commercial spaces and small-to-medium outdoor sites within the 100 m maximum LiDAR range.

Land surveying and topographic mapping
As-built measurement and quantity surveying
Interior measurement and floor plan generation
Stockpile and volumetric measurement
BIM data capture and verification (under 10 m measurement envelope)
Single-building documentation with direct geo-referenced output

K2 in LCC Studio supports Single Model reconstruction. Multi-segment 3DGS projects require the L2 Pro.

PortalCam

Visual Documentation

Used when the primary deliverable is a photorealistic 3DGS model, not a measured point cloud. 96-channel LiDAR with 180° × 180° FOV. Weighs 870 g without tripod. 60-minute battery (vs. 90 minutes for L2 Pro and K2).

Client walkthroughs and virtual tours
Visual progress documentation
Spaces where visual quality matters and measurement is not required

The PortalCam cannot produce point clouds. Do not plan a measured-deliverable project with a PortalCam as the only capture device. Use an L2 Pro or K2 for point cloud output.

Despite the name, the PortalCam is a 96-channel LiDAR scanner with full Multi-SLAM. The LiDAR provides spatial structure for 3DGS reconstruction. "Camera" refers to its emphasis on visual fidelity, not its sensor architecture.

Accuracy conditions matter. Absolute accuracy of ≤3 cm RMSE requires RTK or GCP coverage with no unfixed gap exceeding 100 m (L2 Pro) or 50 m (K2). Relative accuracy of ≤1 cm applies between points within 100 m for L2 Pro and within 10 m for K2. The 3σ qualifier on L2 Pro means approximately 99.7% of measurements fall within the stated range.

Section 5

RTK

The K2 has the UM980 RTK module built in. No external attachment is required. The K2 outputs absolute coordinates directly in WGS84 or CGCS2000 with no post-processing.

The L2 Pro supports RTK via an attachable module. RTK is not built into the base scanner. The module must be attached and configured in LixelGO before the session starts.

L2 Pro RTK Module Variants

Two variants are available: Standard and Survey Grade. Both publish 0.8 cm horizontal and 1.5 cm vertical accuracy. The Survey Grade module adds a higher-gain antenna (5.5 dBi vs. 2.8 dBi) for better performance under partial canopy, near structures, and in urban environments.

Full setup: Module 4: RTK Setup and Field Execution. Introduction to when RTK is needed: 4.1 When Georeferencing Matters.

Aerial RTK module. The L2 Pro also supports a drone-specific RTK module for use with DJI M350 RTK and M300 RTK aircraft. It is not used for handheld scanning. K2 does not support drone mounting.
