High-Precision RTK GNSS Dongles for Centimeter-Level Positioning

Professional RTK GNSS dongles provide high-precision satellite positioning in a compact USB format, making it easy to add centimeter-level GNSS capabilities to computers, industrial systems, robots, vehicles and custom positioning platforms.

GNSS Store offers a wide range of USB RTK GNSS receivers based on professional multi-band chipsets from u-blox, Septentrio, Unicore and Bynav. Available models include USB-A and USB-C receivers, rugged IP67 solutions and advanced all-band GNSS dongles for demanding professional applications.

Centimeter-Level RTK GNSS Accuracy

Unlike standard GNSS receivers that typically provide meter-level positioning, RTK GNSS receivers use correction data to significantly improve positioning accuracy.

With suitable RTK corrections, compatible receivers can achieve centimeter-level positioning, making them suitable for applications where standard GPS accuracy is insufficient.

Our high-precision GNSS dongles include multi-band receivers supporting combinations of L1, L2 and L5 frequencies as well as advanced all-band solutions. Multi-frequency reception helps improve positioning reliability and RTK performance in challenging environments.

Multi-Band USB RTK Receivers

Multi-band GNSS technology allows receivers to track signals across several frequencies and satellite constellations simultaneously.

Depending on the selected model, our RTK dongles can support GPS, Galileo, GLONASS, BeiDou, QZSS, NavIC and other GNSS signals.

The collection includes receivers based on advanced GNSS platforms such as u-blox ZED-F9P, ZED-X20P, NEO-F9P, Septentrio mosaic-X5 and mosaic-G5, Unicore UM980 and UM981, providing options for different accuracy, update rate, interface and integration requirements.

USB-A, USB-C and Industrial IP67 RTK Dongles

Choose between compact USB-A and USB-C RTK GNSS dongles for development and system integration or rugged industrial models designed for demanding environments.

Selected industrial RTK receivers feature IP67 protection, making them suitable for outdoor equipment, agricultural machinery, robotics, vehicles and other applications exposed to dust and moisture.

Many models use an external SMA antenna connection, allowing a suitable multi-band GNSS antenna to be installed in the optimal position for reliable satellite reception.

Advanced GNSS Features for Professional Applications

Depending on the receiver platform, high-precision GNSS dongles may provide advanced capabilities such as anti-jamming, anti-spoofing, dead reckoning, high-rate positioning, timing output and other professional GNSS features.

These capabilities make RTK USB receivers suitable not only for positioning but also for sophisticated autonomous, industrial and research applications.

Always check the specifications of the individual receiver to determine which GNSS bands, constellations and advanced features are supported.

Applications of RTK GNSS USB Dongles

High-precision RTK GNSS dongles are widely used for professional applications including land surveying, geodesy, UAV and drone mapping, precision agriculture, GIS data collection, robotics, autonomous navigation, machine control, construction, mining and marine positioning.

Their compact USB form factor also makes them convenient for GNSS development, research, field testing and OEM system integration where a high-performance external GNSS receiver needs to be connected quickly to a computer or embedded platform.

RTK GNSS Dongle vs Standard GNSS Dongle

The main difference between a standard GNSS dongle and an RTK GNSS dongle is positioning accuracy.

Standard GNSS receivers are suitable for navigation, tracking and applications where meter-level positioning is sufficient. An RTK GNSS dongle is designed for applications requiring significantly higher precision and can achieve centimeter-level positioning when used with compatible correction data and a suitable GNSS antenna.

For surveying, precision agriculture, autonomous machines and other precision positioning systems, an RTK receiver is therefore usually the preferred solution.

How to Choose an RTK GNSS Dongle

When selecting a high-precision GNSS receiver, consider the required accuracy, supported frequency bands, satellite constellations, RTK correction compatibility, positioning update rate, USB interface and environmental protection.

For fixed or protected installations, a compact USB RTK dongle may be sufficient. For outdoor and industrial equipment, consider an IP67 RTK GNSS receiver. Applications requiring maximum satellite availability can benefit from multi-band or all-band receivers.
