HB10 Dual-Antenna RTK GNSS Receiver — Septentrio AsteRx-m3 Pro+
The HB10 is a compact dual-antenna RTK GNSS positioning and orientation receiver powered by the Septentrio AsteRx-m3 Pro+. It delivers 0.6 cm RTK accuracy and 0.15° heading at 100 Hz with <10 ms latency, over three UART ports, USB-C, and Micro SD logging — in a slim 71.8 × 20.5 × 12.5 mm board built for UAVs, autonomous vehicles, and precision control systems.
Description
100 Hz Dual-Antenna RTK GNSS & Orientation Receiver for Industrial UAVs and Autonomous Vehicles
The HB10 is a high-performance dual-antenna GNSS positioning and orientation receiver built on the Septentrio AsteRx-m3 Pro+. It delivers 0.6 cm + 0.5 ppm RTK horizontal accuracy at 100 Hz with ultra-low <10 ms latency, plus heading, pitch, and roll from the dual-antenna baseline. Three UART ports, USB-C, Micro SD logging, and a full suite of Septentrio signal-resilience technologies — AIM+, APME+, IONO+, LOCK+, RAIM+, and OSNMA — make the HB10 a ready-to-integrate navigation solution for demanding, RF-complex environments.
