Satellite positioning is no longer measured in meters. A new generation of correction services blends signals from several GNSS constellations with computer vision and sensor fusion to place a vehicle within a few centimeters. The latest market signal came in November 2025, when US company Point One Navigation raised a 35 million dollar round to expand its correction network. Behind that headline sits a trend that touches any operation that depends on knowing where each asset is.
What is augmented GNSS?
GNSS is the umbrella term for the global navigation satellite systems: the American GPS, Europe’s Galileo, China’s BeiDou and Russia’s GLONASS. A basic receiver that only listens to those signals returns a position with a margin of several meters. Augmented GNSS adds a data layer: ground reference stations measure the signal error in real time and send a correction to the receiver. Point One runs its Polaris network for this, with lunchbox-sized units mounted on cell towers across North America, Europe and Asia. A vehicle must sit within 40 kilometers of a station to reach centimeter level.
Why the centimeter matters
Point One targets a margin of one to three centimeters. «You can’t be off by ten centimeters and go over into a flower bed,» says Tom Weeks, the company’s chief operating officer, describing autonomous lawn mowers. The same requirement shows up in precision agriculture, industrial robots, delivery drones and robotaxis. The company says one electric-vehicle maker already uses the technology across more than 150,000 units and that a distribution firm applies it to 300,000 last-mile vehicles. Adoption among manufacturers grew tenfold in a year.
What it means for fleet management
For a fleet manager, the takeaway is not to adopt one specific vendor but to grasp that position-data quality has become a competitive factor. An accurate, interference-resistant location improves route assignment, delivery verification, geofence control and incident reconstruction. Combining several constellations with ground corrections also adds continuity when one signal degrades. Satellite positioning is not an add-on: it is the foundation on which all telematics is built.
Centimeter accuracy is still concentrated in autonomous applications, but the infrastructure that makes it possible —more constellations, more reference stations, more sensor fusion— benefits the entire tracking chain. At EsencialGPS we follow this shift closely so that every vehicle in your operation reports a reliable position. Learn more at www.esencialgps.cl.
