The Next Big Thing in IoT Is Measured in Centimeters

In partnership with

Hello readers!

This week we’re talking about the practical applications of near perfect location sensing, how In-Factory Profile Provisioning is changing manufacturing, and usecases for Software-Defined Connectivity.

Precision as a Platform

For decades, GPS has been good enough. A few meters of error don’t matter much when you’re trying to find the right highway exit or plotting a delivery route. But as connected devices have moved from guiding vehicles to operating them, the limits of “good enough” have started to show. That’s where a quiet shift now underway could open a whole new future of functionality: the arrival of centimeter-level positioning accuracy for everyday applications.

The latest sign of this shift comes from a partnership between Quectel Wireless Solutions and Swift Navigation, which combines advanced GNSS hardware with Swift’s cloud-based real-time correction network. Together, they aim to make high-precision positioning, once confined to survey-grade equipment, accessible to mass-market IoT developers. The underlying method, known as PPP-RTK (Precise Point Positioning–Real-Time Kinematic), blends global satellite data with real-time cloud corrections to achieve near-instant, centimeter-level accuracy. It’s not just about knowing where something is: it’s about knowing exactly where, with reliability that can scale across continents.

Why does that matter? Because precision transforms what IoT can do. In agriculture, centimeter-level guidance allows autonomous equipment to plant and harvest with near-perfect efficiency. In cities, it enables shared scooters and delivery robots to stay exactly where they belong, navigating curbs, lanes, and crosswalks safely. For logistics and infrastructure, it means mapping underground utilities or managing fleets with pinpoint accuracy, while in industrial settings it allows machines to coordinate in real time without human supervision. As positioning becomes this accurate, location data evolves from a descriptive tool to a control system — a digital nervous system for the physical world.

The ripple effects will be broad. Industries that have already automated sensing and communication will now be able to automate movement with the same confidence. Drones could inspect power lines or crops autonomously. Mining operations could run without GPS dropouts. Construction workers could visualize underground utilities through augmented reality overlays that match the real world to the centimeter. And vehicles could navigate with a safety margin measured in inches, not feet.

Of course, no single technology will solve every challenge. Satellite positioning can struggle in dense urban areas or indoors, where signal interference and obstructions limit reliability. That’s why the future of high-accuracy navigation will likely depend on sensor fusion — combining satellite data with inertial, visual, or radar-based systems to maintain accuracy when one signal fails. Still, the growing accessibility of real-time precision location represents a major step forward for connected systems. It brings us closer to a world where every object that moves, whether a delivery drone to a construction vehicle, knows exactly where it is and can act accordingly.
