FocalPoint Positioning has unveiled Precise+, a software-defined receiver technology that delivers sub-metre GNSS accuracy in environments where conventional carrier phase tracking typically fails — without the use of inertial sensors, dead reckoning, or sensor fusion.
Announced at the European Navigation Conference 2026 in Vienna, Precise+ extends FocalPoint’s patented Supercorrelation platform into the carrier phase domain, directly targeting the cycle slips that cause RTK and PPP systems to lose lock in urban canyons, under foliage, and in multipath-heavy environments. When carrier phase lock is interrupted — a routine occurrence in dense cities and under tree cover — receivers suffer cycle slips and force reinitialisation, the defining barrier to deploying centimetre-level positioning at scale in automotive and robotics applications.
In testing at Thetford Forest, a standard GNSS reference environment for dense-foliage performance, Precise+ delivered 80 cm accuracy at the 99th percentile. State-of-the-art receivers produced errors exceeding three metres in the same conditions. The results are receiver-level only, meaning the gains compound with whatever sensor fusion, RTK, or PPP corrections an integrator applies on top.
“RTK and PPP deliver centimetre accuracy in open sky but degrade sharply where signals are disrupted by tree cover, buildings or multipath,” said Scott Pomerantz, CEO of FocalPoint Positioning. “This limits deployment to a narrow slice of the road network, not the environments people actually drive in.”
Precise+ targets automotive ADAS, automated driving, and V2X applications, and is applicable to any system requiring sustained high-precision GNSS outside open-sky conditions. FocalPoint says it is working with leading chipset manufacturers on commercialization.
