The GD350 UAV Magnetic Survey System, developed by Chongqing Gold Mechanical&Electrical Equipment, is a high-precision, drone-based geophysical solution designed for mineral exploration, utility detection, and scientific research. This system integrates advanced magnetometry, real-time data processing, and terrain-following flight capabilities, making it a superior alternative to traditional ground surveys.
Key advantages include:
Lightweight (1.5 kg payload) - Compatible with DJI M300 RTK for extended flight operations.
Dual-sensor technology - Combines Rubidium OPM and 3-axis Fluxgate Magnetometers for comprehensive magnetic field analysis.
Real-time compensation - Eliminates interference from the drone platform.
Seamless integration - Supports DJI OSDK/PSDK for GPS/RTK data synchronization.
| Component | Specifications | Key Benefits |
|---|---|---|
| Rubidium OPM | - Sensitivity: 20 pT/Hz - Dynamic Range: 1,000-100,000 nT - Weight: 30g (sensor) |
Ultra-high precision for detecting weak magnetic anomalies. |
| 3-Axis Fluxgate Magnetometer | - Noise: <20 pT/√Hz - Orthogonality Error: <1° - Weight: 70g |
Measures vector magnetic fields with minimal distortion. |
| Feature | Details | Advantage |
|---|---|---|
| Processor | 4-core ARM Cortex-A53, 1.2 GHz | Enables real-time data correction at 20Hz sampling rate. |
| Data Output | 24-bit ADC, USB/Wi-Fi telemetry (10Hz transmission) | Ensures high-resolution data logging and live monitoring. |
| Interfaces | 4x USB ports (for IMU, GPS, storage, telemetry) | Supports modular expandability. |
| Parameter | Value | Impact on Surveys |
|---|---|---|
| Flight Time | Up to 55 minutes | Covers large areas in a single mission. |
| RTK GPS Accuracy | ±1.5 cm (horizontal) | Ensures precise georeferencing of magnetic data. |
| Max Payload Capacity | 9 kg (M300 RTK) | Accommodates additional sensors if needed. |
The system includes Windows-based Ground Control Software with the following functionalities:
Terrain-Following Waypoint Planning: Uses DEM data to maintain consistent altitude.
Real-Time Data Display: Visualizes magnetic field readings, GPS coordinates, and altitude.
Automated Compensation: Applies 18-parameter OPM and 12-parameter Fluxgate calibrations.
Post-Processing Tools: Includes data filtering, anomaly mapping, and export to GIS formats.
| Industry | Use Case | System Benefit |
|---|---|---|
| Mining & Exploration | Mapping mineral deposits and ore bodies. | High sensitivity detects subtle magnetic variations. |
| Utility Detection | Locating buried pipelines, cables, and infrastructure. | Real-time data reduces excavation risks. |
| Archaeology | Identifying buried artifacts or structures. | Non-invasive method preserves site integrity. |
| Environmental Studies | Monitoring soil magnetism or pollution. | Rapid aerial surveys save time vs. ground methods. |
Portability & Ease of Deployment
At 1.5 kg, the GD350 is lighter than most industrial magnetometers, reducing drone payload strain.
Plug-and-play installation on the DJI M300 RTK minimizes setup time.
Unmatched Data Accuracy
Dual-sensor fusion (OPM + Fluxgate) provides both scalar and vector magnetic data.
Real-time compensation removes drone-induced noise, ensuring clean datasets.
Cost Efficiency
Reduces manpower needs by replacing ground crews with automated aerial surveys.
Long flight time maximizes area coverage per battery cycle.
