Core Capabilities

Centimeter-Level Precision: By combining GNSS, IMU, and wheel sensors (odometers), the system maintains horizontal accuracy of 0.02m and vertical accuracy of 0.03m, even in challenging urban “canyons.”
360° Vision & Scanning: It features a surveying-grade panoramic camera system (typically 7×5 MP) and a LiDAR unit with a 360° horizontal field of view, ensuring no blind spots during collection.
GNSS-Denied Performance: It utilizes SLAM (Simultaneous Localization and Mapping) technology and intelligent algorithms to continue accurate data collection in tunnels, underground garages, or under heavy tree cover.
High-End Processing Power: Unlike many entry-level units, it carries an onboard 13th Gen Intel i9 processor and supports high-end GPUs (like the RTX 4090) for real-time data handling.

Typical Applications

The M502 is built for industrial-scale projects where speed and accuracy are non-negotiable:

Urban 3D Modeling: Creating high-fidelity digital twins of entire city blocks.
Road Asset Census: Automatically identifying and mapping road signs, lamp posts, and manhole covers.
Highway & Railway Inspection: Monitoring track/road conditions and detecting deformations or maintenance needs.
Infrastructure Assessment: High-speed surveys of bridges, tunnels, and large-scale utilities.

Software Workflow

The system comes paired with Geosun’s proprietary software suite:

POS Software: For calculating precise trajectories and attitude.
PointCloudCreater: For generating and colorizing the raw point clouds (supporting standard formats like .LAS).
