What Is the Best GNSS Board for Robotics? Top Picks for OEM Integration

The best GNSS board for a robot gives centimetre RTK, true heading without a magnetometer, low power and a clean interface to ROS or the autopilot. Eview’s robotics line covers this with the HBEV322 / HBEV322H smart antenna, the HB52 / HB52H and HB50H receivers, the HB51 heading board and the HB59 OEM board, all powered by Septentrio modules with AIM+ anti-jamming.

What a robot needs from a GNSS board

• Centimetre RTK: 0.6 cm + 0.5 ppm horizontal on every Eview receiver. See RTK GNSS.
• Heading without a magnetometer: motors and high-current wiring disturb compasses. Dual-antenna receivers give 0.15° heading at 1 m spacing. See dual-antenna heading explained.
• Interference resilience: motors, ESCs, Wi-Fi and LTE all add noise. Septentrio AIM+ is on by default in every Eview receiver. See AIM+.
• Low power: mosaic-G5 receivers start at 0.44 W (HB50).
• Clean integration: NMEA, SBF and RTCM v3 over UART or USB, plus Ethernet on the HB59.

Eview robotics boards and receivers compared

Model	Module	Heading	Max rate	Best for
HBEV322 / HBEV322H	mosaic-G5	HBEV322H	20 Hz	Simplest install on small robots
HB52 / HB52H	mosaic-G5	HB52H	20 Hz	Payload-limited robots, logging
HB50H	mosaic-G5 P3H	Yes	20 Hz	Battery robots, lowest power heading
HB51	mosaic-G5 P3H	Yes + RM3100 magnetometer	20 Hz	Heading with a backup sensor
HB6	mosaic-X5	No	100 Hz	Fast robots needing position only
HB59	AsteRx-m3 Pro+	Yes	100 Hz	Custom electronics with Ethernet

How Eview compares with common bare modules

Many robot builders start with a u-blox ZED-F9P or Unicore UM982. From the manufacturers’ public datasheets: the ZED-F9P has 184 channels and runs RTK at about 5–7 Hz with four constellations; the UM982 gives 0.1° dual-antenna heading at up to 20 Hz. Eview receivers add Septentrio AIM+ against wideband and pulsed interference, Galileo OSNMA on mosaic-X5 and mosaic-G5 models, and come as finished, tested hardware. See the full comparison.

Integrating with ROS, ArduPilot and PX4

• ROS / ROS 2: Septentrio maintains a ROS driver for its receivers, publishing fix, heading and raw data. See connecting a Septentrio receiver to ROS.
• ArduPilot and PX4: connect over UART with NMEA or SBF; dual-antenna models can provide heading to the autopilot. See GNSS for ArduPilot.
• Corrections: RTCM v3 from NTRIP, your own HB62 base, or Galileo HAS on mosaic-G5 products for decimetre-level accuracy without a base.

Pick by robot type

• Outdoor AMRs and delivery robots: HBEV322H or HB52H.
• Robotic lawn mowers: HBEV322 or HB50 with an HB62 base.
• Robot dogs: HB52H or HB50H.
• Agricultural robots: HB50H or HB6 Pro.
• Fast or large vehicles: HB10 or HB59 at 100 Hz.

Frequently asked questions

What is the best GNSS board for robotics?

For most outdoor robots, a dual-antenna mosaic-G5 receiver such as the Eview HBEV322H, HB52H or HB50H gives centimetre RTK, 0.15° heading and low power. For 100 Hz control or Ethernet, choose the HB59 OEM board.

Do I need dual-antenna heading on a robot?

If the robot must know its heading while stationary or moving slowly, yes. Magnetometers are disturbed by motors and wiring; dual-antenna GNSS is not.

Do Eview receivers work with ROS 2?

Yes. Septentrio provides a ROS driver for its receivers, and Eview receivers output standard NMEA, SBF and RTCM v3.

Which Eview board has Ethernet?

The HB59 OEM board (AsteRx-m3 Pro+), and the HB62 base station.
