OEM GNSS receiver board for base, rover and heading
The Eview HB59 is a multi-frequency OEM GNSS receiver board built around the Septentrio AsteRx-m3 Pro+. It is made for engineers who build GNSS into their own machines, enclosures and control systems. One board can work as an RTK GNSS receiver rover, as a base station, or with two antennas for heading and pitch or roll. The HB59 is the board-level sibling of the HB10 dual-antenna receiver: it uses the same GNSS engine and adds Ethernet for system integration. It is part of our AsteRx-m3 GNSS boards.
RTK positioning and dual-antenna heading
The AsteRx-m3 Pro+ tracks GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC and SBAS on multiple frequencies with 544 hardware channels. RTK accuracy is 0.6 cm + 0.5 ppm horizontal and 1 cm + 1 ppm vertical, with a typical 7 s initialization. With a second antenna on the AUX1 input, the HB59 gives 0.15° heading and 0.25° pitch or roll at 1 m antenna spacing, and 0.03° / 0.05° at 5 m, without the vehicle having to move. See how dual-antenna GNSS heading works.
100 Hz output with low latency
Position and raw measurements are available at up to 100 Hz (1 Hz by default), with latency below 10 ms for 99.9% of epochs. This suits fast control loops in autonomous vehicles, machine control and flight systems. LOCK+ keeps tracking stable under strong vibration and fast movement.
AIM+ anti-jamming and OSNMA anti-spoofing
Septentrio AIM+ detects and suppresses narrowband and wideband interference, and Galileo OSNMA authenticates satellite navigation data to protect against spoofing. IONO+ protects RTK during ionospheric scintillation, APME+ reduces multipath near buildings and metal structures, and RAIM+ monitors position integrity.

Ethernet, serial and logging for integration
The HB59 board carries Ethernet, three UARTs (115200 bps to 4 Mbps), USB 2.0 on Type-C, a 1PPS output, an event input, reset, and a microSD slot for raw data logging up to 32 GB. It accepts and outputs RTCM v2.x/v3.x and CMR/CMR+ corrections, and outputs NMEA 0183 and Septentrio SBF. The board runs from 4.5–12 V DC at about 1.6 W and operates from -40 °C to +85 °C. Firmware and manuals are on our firmware downloads page.
Applications
- Autonomous robots and vehicles: centimetre position and heading for unmanned ground vehicles and AGVs.
- Industrial drones: 100 Hz RTK and heading for flight control and mapping payloads.
- Construction and mining: machine control and guidance in harsh, high-multipath sites.
- Precision agriculture: auto-steering and implement control with low-latency RTK.
- Marine: GNSS heading and position for vessels and unmanned surface vehicles.
- Deformation monitoring: networked reference and monitoring stations over Ethernet.
Frequently asked questions
What is the difference between the HB59 and the HB10?
Both use the Septentrio AsteRx-m3 Pro+ and give the same RTK, heading and 100 Hz performance. The HB10 is a ready-to-use receiver; the HB59 is an OEM board that adds Ethernet for system integration.
Can the HB59 be used as an RTK base station?
Yes. The HB59 can be configured as a base or a rover. As a base it outputs RTCM v2.x/v3.x or CMR/CMR+ corrections over serial or Ethernet. See our guide to NTRIP, RTCM and RINEX integration.
Does the HB59 need two antennas?
No. With one antenna on the MAIN input it gives RTK position. Add a second antenna on AUX1 for heading and pitch or roll. Both inputs supply 3.0–5.5 V antenna bias, 150 mA maximum.
What power supply does the HB59 need?
Use a 4.5–12 V DC supply. Typical current is 330 mA at 5 V (about 1.6 W). Ripple on VCC should stay below 50 mV.
