Precision Positioning for the Autonomous Robot Era

Outdoor autonomous robots — from last-mile delivery bots to field robots and inspection platforms — require reliable, centimeter-accurate positioning to navigate safely and execute tasks precisely. Standard GPS (1–3 m accuracy) is insufficient; RTK GNSS is the baseline.

Eview GNSS modules deliver centimeter-level RTK with fast convergence, ROS2 driver support for direct robot OS integration, and AIM+ anti-jamming for robots operating in RF-complex environments: urban streets, industrial facilities, and agricultural fields near cell towers.

Applications

Robotics & Autonomous Vehicle Use Cases

From robotic dogs navigating rough terrain to AGVs in logistics yards — Eview RTK GNSS powers reliable outdoor autonomy.

🤖
AMRs & AGVs
Autonomous Mobile Robots and Guided Vehicles need centimeter RTK for precise docking, path following, and geofencing in outdoor logistics yards.
🐕
Robotic Dogs & Legged Robots
Quadrupedal robots on uneven terrain use RTK GNSS for global localization — essential for returning to base and coordinating multi-robot tasks.
📦
Last-Mile Delivery Robots
Urban delivery robots use AIM+ anti-jamming to maintain positioning in RF-congested cities, with honest accuracy reporting for safe failsafes.
🔍
Inspection & Patrol Robots
Facility inspection and perimeter patrol robots use RTK for GPS-waypoint mission execution, anomaly location tagging, and precise return-to-base.
🌱
Weeding & Crop Robots
Agricultural robots navigating between crop rows require sub-inch RTK accuracy. Compact Eview modules enable season-long autonomous operation.
🏭
Industrial Automation
Outdoor industrial robots on factory grounds and port facilities use high-dynamics RTK with dual-antenna heading for safety-critical positioning.
FAQ

Robotics GNSS — Frequently Asked Questions

What GNSS accuracy do outdoor autonomous robots need?
Outdoor robots typically need 2–5 cm RTK accuracy for reliable waypoint navigation. Robots performing precision tasks (row-following, docking) need <1 cm. Eview RTK modules deliver <1 cm + 0.5 ppm with <10 second convergence time.
Do Eview GNSS receivers support ROS and ROS2?
Yes. Septentrio provides open-source ROS and ROS2 driver packages for Eview receivers. The driver publishes NavSatFix, TwistWithCovarianceStamped, and TimeReference messages — directly usable with robot navigation stacks like Nav2.
How does dual-antenna GNSS benefit autonomous robots?
A dual-antenna configuration provides heading and pitch angles directly from GNSS — without a magnetic compass. This is critical for robots near steel structures, electric motors, or magnetically noisy industrial environments where compasses give erroneous readings.
What is APME+ multipath mitigation and why does it matter for robots?
APME+ reduces positioning errors caused by reflected satellite signals — common near buildings, vehicles, and metallic structures. For urban delivery robots and industrial robots near large structures, APME+ significantly improves RTK solution quality in challenging environments.
