• Platform: Multi-rotor UAV

Why GS-260X for Urban Projects?

Urban environments demand high-resolution, efficient, and stable scanning solutions. The GS-260X delivers on all fronts with its advanced specifications:

1. Superior Laser Scanning Power

• Measuring Range: Up to 300m, allowing high-altitude surveys across dense urban zones

• Accuracy:

  • Range Accuracy: 0.5 cm

  • Absolute Accuracy: 10 cm @150 m

• Point Density:

  • 160 pts/m² at 100m flight height

  • 80 pts/m² even at 150m

• Triple Echo & 32 Laser Channels for enhanced returns on complex building surfaces

• Point Throughput: Up to 1.92 million pts/sec ensures complete urban coverage at flight speed

2. Highly Accurate Positioning System (POS)

• IMU: gSpin 310, 200Hz update rate

• Position Accuracy:

  • Horizontal: 2 cm

  • Vertical: 3 cm

• Orientation Accuracy:

  • Pitch/Roll: 0.005°

  • Heading: 0.017°

• GNSS: GPS, GLONASS, GALILEO, BDS – ensures reliable performance even in urban canyons

3. RGB Camera Integration for Textured Modeling

• Resolution: 26 MP

• FOV: 80°

• Enables generation of colorized point clouds and photogrammetry-based textured 3D models

Deliverables & Outcomes

• Full-Scale 3D Mesh Model of commercial and residential blocks

• Digital Elevation Models (DEM/DSM) used for zoning, planning, and drainage analysis

• Building Information Modeling (BIM) integration from classified point cloud data

• Textured Orthophotos for façade condition analysis and urban landscape planning

Efficiency Gains

Client Testimonial

“With the GS-260X, we completed urban zone mapping 30% faster than traditional methods, while achieving sub-decimeter precision. The triple-echo capability was particularly valuable in tree-lined residential zones.”
