GNSS Receiver for Robotics: RTK and Heading for Robots and AMRs

Q: Which Eview GNSS receiver is best for an outdoor robot?

For small delivery robots and AMRs, the HBEV322 smart antenna combines receiver, antenna and compass in one unit. For compact robots that need heading, choose the HB52H or HB50H. For robots with their own electronics and fast control loops, the HB59 OEM board offers 100 Hz output and less than 10 ms latency.

Q: Why use dual-antenna heading on a robot?

Dual-antenna GNSS gives a true heading of 0.15° at 1 m spacing while the robot is stationary. Magnetometers are disturbed by motors, batteries and steel structures, and a single antenna only gives heading once the robot is moving. The HB6 Pro also provides pitch and roll of 0.25° at 1 m.

Q: Can GNSS work on its own for robot navigation?

GNSS gives absolute position outdoors, but under roofs, dense trees or between tall buildings the signal can drop. Most robots fuse RTK GNSS with wheel odometry, an IMU, lidar or cameras. RAIM+ integrity flags help the navigation stack decide when to trust or de-weight GNSS positions.

Q: How do robots get RTK corrections?

Robots receive RTCM v3 corrections over LTE or Wi-Fi from an NTRIP caster or CORS network, or over a radio link from a local base station. The HBEV11 smart antenna can act as a portable base, and the HB62 rugged base receiver serves NTRIP over Ethernet for larger sites.

Q: Do Eview receivers resist interference from robot electronics?

Yes. Septentrio AIM+ detects and suppresses narrowband and wideband interference from Wi-Fi, LTE modems and motor drives, and Galileo OSNMA authenticates signals on mosaic-G5 and AsteRx receivers. Antenna placement away from noisy electronics still matters; the EV226 magnetic-mount antenna on a 3 m cable makes this easier.

Q: What is the best GNSS for robotics and automation?

For most outdoor robots and automated vehicles, choose a multi-band RTK receiver with dual-antenna heading and interference mitigation. Eview options: the HBEV322 smart antenna for small AMRs and delivery robots, the HB52H or HB50H for compact robots that need heading, the HB6 Pro for heading on larger vehicles, and the HB10 or HB59 OEM board for 100 Hz control loops. All use Septentrio modules with AIM+.

Q: Can I use a Septentrio GNSS receiver with ROS?

Yes. Septentrio-based Eview receivers output NMEA and SBF binary over serial, USB or Ethernet, and an open-source ROS driver is available, so the position and heading can feed ROS navigation directly.

Q: How accurate is RTK GPS for an autonomous mobile robot?

With RTK corrections from a local base or NTRIP service, Eview receivers reach about 1 to 2 cm horizontal accuracy in open sky. That is enough for path following, docking and repeatable inspection routes.

Q: What is robotics GNSS?

Robotics GNSS is satellite positioning built for robots and automated machines: a multi-band RTK receiver, often with dual-antenna heading, that gives the robot's localisation stack centimetre position and true heading outdoors.

Q: Can a robot GNSS receiver work indoors?

No. GNSS signals do not reach reliably indoors, so robots that drive both indoors and outdoors fuse GNSS with SLAM, wheel odometry and an IMU, and hand over between them at doorways and covered areas.

Eview RTK GNSS for robots gives outdoor autonomous mobile robots, AGVs and delivery robots centimetre positioning and true dual-antenna heading, powered by Septentrio modules with AIM+ anti-jamming. Choose an all-in-one smart antenna, an ultralight receiver, a compact heading receiver or a 100 Hz OEM board that connects directly to your robot’s controller.

What robots need

What an outdoor robot needs from its GNSS receiver

Centimetre accuracy

Path following on pavements, campuses and yards needs repeatable positions. RTK accuracy of 0.6 cm + 0.5 ppm with about 7 s initialisation keeps robots on their planned route. See RTK positioning.

Heading at standstill

A robot must know which way it faces before it moves. Dual-antenna GNSS heading gives 0.15° at 1 m spacing without driving and without magnetometer errors from motors. See dual-antenna heading.

Robust near buildings

Robots work next to walls, trees and parked vehicles. APME+ multipath mitigation and LOCK+ tracking help hold an RTK fix, while RAIM+ flags unreliable positions to the navigation stack. See RAIM+ integrity.

Resistance to interference

On-board Wi-Fi, LTE modems and motor drives create RF noise. Septentrio AIM+ suppresses interference, and Galileo OSNMA authenticates signals on mosaic-G5 and AsteRx receivers. See anti-jamming receivers.

Fast, low-latency output

Control loops need fresh data. The HB59 OEM board outputs up to 100 Hz, mosaic-G5 receivers run at 20 Hz, and the HB52 and HB59 keep latency below 10 ms. See 100 Hz GNSS.

Small size and low power

Battery-powered robots need compact, efficient receivers. The HB52 measures 48 × 35 × 12.6 mm, the HB50H draws 0.60 W, and the HBEV322 combines receiver, antenna and compass in one housing.

Use cases

Robotics applications

Last-mile delivery robots

Pavement and campus delivery robots use RTK and heading to follow routes and stop at exact drop-off points.

Robotic lawn mowers

Centimetre RTK replaces the boundary wire for mowing robots in gardens, parks and sports fields. See lawn mowing robots.

Field and agricultural robots

Weeding, scouting and harvesting robots follow crop rows with RTK position and dual-antenna heading. See precision agriculture.

Legged robots

Quadruped robots carrying inspection payloads use lightweight receivers to navigate outdoor sites and geotag their findings. See robot dogs.

Inspection robots

Robots inspecting solar farms, substations and pipelines need repeatable positions to revisit the same checkpoints. See inspection and patrol.

Yard and port vehicles

AGVs and autonomous tractors in yards and ports combine RTK with heading for docking and container handling. See autonomous vehicles.

Integration

Easy to integrate

Robot controllers

UART, USB-C and Ethernet interfaces output NMEA and Septentrio SBF that robot navigation software can read. See GNSS boards for robotics.

Corrections

RTCM v3 from an NTRIP caster, a CORS network or your own base, such as an HBEV11 smart antenna on a tripod. See NTRIP and RTCM.

Logging and firmware

Raw data logging to microSD on the HB52 for analysis and RINEX conversion. Firmware and manuals are on firmware downloads.

Use cases

RTK GNSS for outdoor mobile robot positioning

An outdoor robot needs to know where it is to the centimetre and which way it is facing, even under trees, next to buildings and near electrical noise. Eview RTK receivers, powered by Septentrio modules, give every class of autonomous mobile robot a precise position and, with two antennas, true heading at standstill.

Autonomous mobile robot GPS

For an autonomous mobile robot or autonomous ground vehicle, RTK GPS keeps the robot on its planned path across yards, campuses and job sites. It also works for autonomous forklifts and tuggers that move between outdoor and covered areas.

Inspection robot GPS and industrial robot GNSS

An inspection robot in a power plant, an electric substation, or on a pipeline or oil and gas site must repeat the same route and tag every reading with an exact position. AIM+ anti-jamming protects the fix near transformers and radios.

Security robot GPS patrol

Perimeter security and patrol robots follow fence lines and checkpoints day and night. RTK positioning keeps every patrol route repeatable to a few centimetres, so alarms and camera images match an exact location.

Construction robot GPS and port automation

Construction robots, mining robot navigation, autonomous haulage and port automation vehicles work in harsh environments. Rugged box receivers handle vibration, dust and wide temperature ranges.

Hazardous and search and rescue robots

Robots sent into hazardous environments or used for search and rescue rely on GNSS to report exactly where they are and to return along a known path.

Multi-robot fleet GPS coordination

When several robots share one site, a single RTK base or NTRIP service puts every robot in the same reference frame. This makes multi-robot fleet coordination much simpler.

Warehouse and outdoor cleaning robots

Warehouse robot GPS for yard-to-dock moves, and outdoor cleaning robots that sweep car parks, campuses and streets, use RTK to cover every metre without gaps or overlaps.

Autonomous ground vehicle GNSS

Autonomous ground vehicles, tuggers and shuttles on private sites use the same RTK and heading receivers, with standard NMEA output for the vehicle computer.

Choosing a precision GPS receiver for robotics: use an OEM GNSS board inside your own enclosure, a box receiver for quick integration, or a smart antenna for small robots. Ask us at sales@gnss-solutions.com.

Guide

Robotics GNSS in automation: where GNSS fits in the robot stack

Robotics GNSS gives an outdoor robot its absolute position and heading in a global frame. It does not replace the robot’s other sensors; it anchors them. A typical outdoor automation stack combines:

RTK GNSS for centimetre position in a fixed map frame, so routes, geofences and docking points stay valid day after day.
Dual-antenna GNSS heading for true heading at standstill, without the magnetometer errors caused by motors and batteries.
Wheel odometry and IMU to bridge short GNSS outages under trees, next to buildings or under bridges.
Lidar or camera SLAM for obstacle avoidance, and for indoor or covered areas where GNSS is not available.

In ROS 2, the robot GNSS receiver usually feeds robot_localization: position as a NavSatFix into navsat_transform, heading as an orientation input, and an EKF fuses both with odometry and IMU. A few practical rules for automation projects:

Check the fix type, not just the position. Use RTK fixed for tight path following, and inflate the covariance in float or DGPS.
10–20 Hz output suits slow robots; fast control loops need up to 100 Hz with low latency.
Mount the antenna as high and as clear as the robot allows. Low mounts near the ground see more multipath. Our field review of RTK under tree canopy shows what happens to fix status when the sky view is blocked.
For mixed indoor-outdoor routes, let localisation hand over gradually between GNSS and SLAM instead of switching hard.

For sizing details, see outdoor GNSS for mobile robots (AMRs) and GNSS with heading explained.
