The Here3 is an RTK-enabled high-precision positioning module for UAVs and unmanned systems, based around the u-blox M8P GNSS chipset as well as ARM Cortex CPU running a real-time operating system (RTOS). When used in conjunction with an RTK base station, it provides positioning capabilities down to centimetre-level accuracy.

The system has been designed around an in-house developed fully-supported software framework for enhanced reliability and extendability. The architecture uses the CAN protocol, providing higher data rates, noise immunity and real-time capabilities.

The compact and lightweight GNSS module is enclosed in a dust-and water-resistant housing and features an integrated magnetometer and compass for enhanced navigation performance.
