Dual-Antenna GNSS Heading Dongles

High-Precision Dual-Antenna GNSS Heading Receivers

Our collection of dual-antenna GNSS heading dongles combines high-performance RTK positioning with precise real-time heading measurements in compact USB-connected receivers. Unlike conventional single-antenna GNSS receivers, dual-antenna systems calculate heading directly from the relative position of two GNSS antennas, providing accurate orientation even when the vehicle or platform is stationary.

Designed for professional navigation and automation systems, these receivers support multi-band, multi-constellation GNSS including GPS, Galileo, GLONASS, BeiDou, QZSS, and NavIC, depending on the receiver model. With fast RTK initialization and centimeter-level positioning accuracy, they provide reliable heading information without relying on magnetic compasses, making them ideal for environments affected by magnetic interference.

Our selection includes professional solutions based on industry-leading GNSS technologies from manufacturers such as Septentrio, u-blox, and Unicore. Depending on the model, features may include dual-antenna moving baseline technology, advanced RTK algorithms, anti-jamming and anti-spoofing protection, Galileo High Accuracy Service (HAS), low-latency measurements, and update rates of up to 100 Hz for demanding navigation applications.

These USB GNSS heading receivers are suitable for both OEM development and ready-to-use integration into robotics, autonomous systems, surveying equipment, marine electronics, agricultural machinery, unmanned vehicles, and research platforms where precise heading and positioning are essential.
