Introducing Chongqing Gold Mechanical&Electrical Equipment Co.,Ltd.'s GD Series: The Pinnacle of UAV Magnetic Survey Technology
Chongqing Gold Mechanical&Electrical Equipment Co.,Ltd. proudly presents the GD Series UAV Magnetic Survey System, an industry-leading solution designed for unparalleled geophysical exploration accuracy. This ultra-portable system integrates seamlessly with the robust DJI M300 RTK platform, defining a new benchmark in aerial magnetic data acquisition efficiency and precision.
Core Innovation: Dual-Sensor Fusion & Real-Time Compensation
The GD Series stands apart through its sophisticated dual-sensor architecture. At its heart lies a cutting-edge Miniature Rubidium Optical Pump Magnetometer (OPM) renowned for exceptional field sensitivity. Complementing this is a meticulously Software Calibrated 3-Axis Low Noise Fluxgate Magnetometer. Crucially, both sensors are strategically positioned 1.5 meters away from the drone's center, minimizing inherent platform interference from the outset. The system's true genius lies in its proprietary real-time compensation and correction algorithms. Powered by a dedicated Data Acquisition Module (DAQ) equipped with a quad-core ARM Cortex-A53 processor, the GD Series continuously processes OPM total field measurements, Fluxgate vector field data, high-precision GPS positioning, laser altimeter readings, and 9-axis IMU attitude data. This integrated processing enables instantaneous removal of residual magnetic noise generated by the DJI M300 RTK, delivering unprecedentedly clean and accurate magnetic field readings directly comparable to ground-based surveys. Eliminating the need for complex post-processing corrections saves significant time and resources.
Unmatched Portability and Integration
Weighing a mere 1.5 kg, the GD Series payload exemplifies ultra-lightweight design without compromising performance. Constructed primarily from advanced carbon fiber composites, the sensor housing and telescopic boom ensure exceptional rigidity and minimal magnetic signature. Integration with the DJI M300 RTK is seamless, leveraging the DJI OSDK open interface to access the drone's high-fidelity RTK GPS data and flight telemetry. This synergy creates a powerful, unified survey platform. Effortless deployment translates directly to increased survey productivity in the field.
Comprehensive Data Capture and Ground Control
Data is captured at a robust 10Hz sampling rate, ensuring high-resolution mapping. The DAQ module offers dual output capabilities: reliable on-board storage via USB drive and real-time wireless telemetry transmission to the dedicated Ground Station Software. This Windows PC-based application is far more than a simple data viewer. It provides powerful tools for real-time data visualization, quality assessment (allowing operators to instantly verify data integrity), downloading, and plotting. Furthermore, it incorporates specialized algorithms for calculating the critical 18-parameter compensation for the OPM and the 12-parameter compensation for the Fluxgate magnetometer, essential for maintaining absolute accuracy.
Intelligent Flight Planning for Complex Terrain
A standout feature of the GD Series Ground Station Software is its advanced terrain-following waypoint planning capability. Utilizing imported Digital Elevation Model (DEM) data, the software intelligently generates flight paths that precisely maintain a constant sensor height above ground level, even over dramatically varying topography. This automated terrain following is absolutely critical for acquiring consistent, high-quality magnetic gradient data, eliminating manual piloting errors and ensuring optimal sensor performance throughout the survey grid.
