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.
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 productionOur 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)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 screeningFor 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 designOur 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
