About us

Home     About us



GeoSurfs Technology Limited was established in 2016 in Hong Kong. Our core business focuses on the development and sales of customized products based on high-precision GNSS modules and antennas. With over 15 years of industry experience, we have built four professional sales and technical support teams specializing in GNSS receivers, positioning modules, IMU/INS components, and application-specific solutions.

We provide cutting-edge GNSS positioning technologies tailored for UAVs, surveying, marine systems, robotics, and machine automation. Our innovative solutions deliver exceptional reliability, precision, and interference resilience, powered by strong R&D from Septentrio NV.

As the market evolved, we transformed into a GNSS hardware system provider, embracing automation and smart sensing technologies. Today, we stand at the forefront of modern navigation and positioning industries, with a production and service network spanning across China to ensure timely delivery and comprehensive customer support.

PCB Design & Manufacturing

At the heart of our operation is a state-of-the-art PCB manufacturing facility. From prototyping to large-scale production, our facility features advanced surface mount board production technology. Our skilled engineers ensure optimized board layout, signal integrity, stack-up, and thermal management.

We specialize in HDI, rigid-flex, and high-frequency PCBs for GNSS systems, UAVs, and autonomous platforms.

Capabilities include:

•  Multi-layer PCB production
Advanced SMT assembly lines
Automated Optical Inspection (AOI)
In-Circuit Testing (ICT) systems

Precision Assembly & Testing

Our SMT assembly lines are equipped with high-speed pick-and-place machines, enabling placement of ultra-small components (down to 01005 size). Using reflow ovens, wave soldering, and selective soldering, we ensure precise assembly.

Each production batch undergoes:

AOI (Automated Optical Inspection)
X-ray analysis (for BGA and hidden joints)
Functional testing
Statistical process control monitoring


Quality Control & Testing

We implement rigorous testing and traceability protocols to ensure defect-free delivery. All boards are tested to meet or exceed IPC Class 2/3 standards, based on customer specifications.

Testing processes include:

Environmental stress screening
Burn-in testing
Real-time production monitoring
Full traceability across production batches

Custom Design & Engineering Support

For specialized needs, our engineers support custom panel design, controlled impedance boards, high-speed signal routing, and thermal simulations. Whether it's antenna integration, RF shielding, or complex multi-board assemblies, we deliver optimized solutions.

With deep expertise in high-speed routing, controlled impedance, and thermal simulation, we help clients shorten development cycles and optimize system performance.

Engineering support includes:

Custom PCB design
High-speed signal and RF design
Thermal management solutions
Design for manufacturability (DFM)


Global Supply Chain & Logistics

Our logistics center ensures fast and reliable global delivery. We maintain ready-to-ship inventory and collaborate with major component suppliers to support just-in-time, express, and bulk shipment programs.

Logistics Capabilities:

Global shipping and fulfillment
Strategic sourcing and procurement
Inventory management services
Express delivery options
