Here4 Multiband RTK GPS Receiver

Here4 is a professional-grade, dual-band RTK GNSS and navigation module designed for applications that demand centimeter-level accuracy and fast, reliable positioning. Supporting all major global satellite constellations—including GPS, Galileo, GLONASS, BeiDou, and QZSS—Here4 delivers precise navigation even in challenging environments.

By leveraging multi-frequency DGNSS signals and advanced positioning algorithms, Here4 achieves an RTK fix within seconds, enabling consistent, stable accuracy down to the centimeter. This makes it ideal for surveying, mapping, industrial drones, and precision-critical UAV operations.

More than just a GNSS receiver, Here4 integrates navigation, sensing, and control capabilities into a single compact unit. With built-in flight control interfaces, PWM/BDSHOT outputs, RC input, hotshoe support, and camera trigger functionality, it serves as a self-contained solution for both navigation and payload coordination.
