Market overview

From boundary wires to autonomous operation

The robotic lawn mower market has evolved rapidly over the past three decades. Early autonomous mowers from the 1990s relied on physical boundary wires and random navigation patterns. The late 2010s brought GNSS-based guidance and virtual geofences - but these solutions still required setting up and maintaining a local RTK base station at each property.

Today, cloud-based correction services have made it possible to eliminate local base stations entirely, enabling truly plug-and-play autonomy at scale. This shift lowers the barrier for manufacturers to build consumer-grade autonomous products, and for service operators to deploy and manage large fleets without complex on-site infrastructure.

Evolution from boundary wires to fully autonomous operation

1830s–1980s:  Human-steered.  Manual push mowers and ride-on mowers dominated, driven by mechanical ingenuity rather than positioning technology.

1990s:  Early robotics.  First autonomous mowers used physical boundary wires and random navigation patterns. No GNSS involvement.

2010s:  GNSS + local RTK.  Virtual geofences replaced physical wires. Local RTK base stations delivered precise positioning but required per-property installation and maintenance.

Now:  Fully autonomous.  Cloud-delivered correction services like PointPerfect Flex eliminate the need for any local infrastructure. Professional-grade accuracy at consumer scale.

Technical challenges

Operating in real backyards is harder than it looks

Residential environments present some of the most demanding GNSS conditions found in any robotic application. Unlike open agricultural fields or construction sites, a typical backyard is a compact, obstacle-rich space where signal quality and reliability must be maintained at all times. Challenges include the following:

The u-blox approach

How cloud RTK correction replaces the local base station 

u-blox addresses the full stack -from GNSS chipsets and antennas to cloud-based correction services and business integration tools. By pairing its leading ZED-F20P module with the PointPerfect correction service, u-blox delivers an end-to-end solution purpose-built for scalable autonomous robotics.

GNSS hardware: F20 high-precision GNSS platform

u-blox's triple-band GNSS platforms feature state-of-the-art signal tracking, native SPARTN format support, and proprietary multipath mitigation technology. The F20's triple-band capability enables superior atmospheric modeling, essential for maintaining a high RTK Fix Rate in demanding residential environments.

• L1/L2/L5  multi-constellation support
• Best-in-class atmospheric modelling supports baselines of up to 100 km
• Native SPARTN correction format for low bandwidth overhead 
• Superior anti-jamming and spoofing protection
• Optimized for compact robotic form factors

Correction service: PointPerfect Flex PPP-RTK correction service

PointPerfect is a cloud-based PPP-RTK correction service drawing on hundreds of real-time reference stations worldwide. PointPerfect Flex, designed for usage-based deployments like seasonal lawn robots, delivers centimeter-level accuracy over the internet -no local base station needed, and bandwidth consumption kept minimal through the highly compressed SPARTN format.

• PPP-RTK corrections for fast convergence and wide coverage
• Internet delivery -no local base station infrastructure required
• Usage-based flexible plans suited to seasonal robots
• Built-in redundancy across hundreds of reference stations

Deployment at scale

A service-to-service partnership

Deploying thousands of autonomous mowers across a region requires more than a technical solution. The service-to-service relationship between u-blox and equipment manufacturers is designed to make large-scale deployment straightforward, with the operational visibility and flexibility to grow.

Backend integration.  Seamless API integration into your existing customer management and device platforms.

Transparent billing.  Flexible, usage-based subscription models with clear per-device billing and no minimum commitments.

Service level agreement.  Defined SLAs covering uptime, correction accuracy, and response times for critical issues.

Metrics and status dashboard.  Real-time visibility into fleet positioning performance, service health, and per-device diagnostics.

 

Benefits

Why manufacturers choose u-blox

u-blox's integrated approach reduces development time and operational complexity while delivering positioning performance that rivals traditional local RTK setups -without the infrastructure burden on a global scale.

	Centimeter-level accuracy without a base station.  ZED-F20P and PointPerfect Flex delivers positioning accuracy comparable to local RTK -removing the complexity of per-installation base station setup entirely.		Scalable fleet deployment.  Usage-based billing, backend APIs, and a performance dashboard make it practical to manage hundreds or thousands of deployed devices.
	Tightly coupled hardware and service.  Native SPARTN support in u-blox chipsets eliminates integration friction and ensures the correction data is interpreted as designed.		Robust in challenging environments.  Proprietary multipath mitigation and triple-band tracking on the F20 platform maintain high RTK Fix Rates even in yards surrounded by trees and structures.
	Reduced time to market.  Pre-integrated hardware and service pairings, combined with dedicated customer support, shorten the path from prototype to production launch.		Proven in real-world conditions.  u-blox continuously validates its solutions in actual residential environments -yards surrounded by houses, fences, and dense tree cover -not just open-sky test beds.
