HB59 Multi-Function OEM GNSS Receiver — Septentrio AsteRx-m3 Pro+
The HB59 is a 544-channel OEM GNSS receiver built on the Septentrio AsteRx-m3 Pro+, combining 100 Hz RTK positioning, dual-antenna heading, built-in Ethernet, and Micro SD logging in a compact 71.8 × 50.2 mm board. Configurable as base station or rover, it serves UAV navigation, autonomous robots, agricultural machinery, and GNSS reference applications.
Description
544-Channel OEM GNSS Receiver with Ethernet, 100 Hz RTK & Dual-Antenna Heading
The HB59 is a high-performance OEM GNSS receiver powered by the Septentrio AsteRx-m3 Pro+. It delivers 0.6 cm + 0.5 ppm horizontal RTK accuracy at 100 Hz with sub-10 ms latency, and in dual-antenna configuration adds heading, pitch, and roll output. Three UART ports, built-in Ethernet, USB-C, onboard Micro SD logging, and a wide 4.5–12.0 V supply make the HB59 a versatile platform. Septentrio’s AIM+, IONO+, LOCK+, APME+, and RAIM+ protection suite is embedded as standard, with OSNMA authenticated positioning via firmware.
