Focal Point Positioning, the UK-based developer of GNSS-enhancing software, has announced Precise+, a new technology that delivers reliable high-precision positioning in tough environments where conventional carrier phase tracking fails. Unveiled at the European Navigation Conference 2026 in Vienna, Austria, Precise+ extends the benefits of the company’s patented Supercorrelation® platform into the carrier phase domain. It directly targets the cycle slips that cause Real-Time Kinematic (RTK) and Precise Point Positioning (PPP) systems to lose lock in challenging environments.
Centimetre-level positioning depends on continuous carrier phase lock. When that lock is interrupted – a routine occurrence in dense cities, under tree cover, and in multipath-heavy environments – receivers suffer cycle slips and force the system to reinitialise. For ADAS, automated driving and robotics, these interruptions are the defining barrier to deployment at scale.
Precise+ solves the problem at its source. It brings the benefits of the company’s patented Supercorrelation® to precise Global Navigation Satellite System (GNSS) positioning, significantly improving performance in challenging environments: sub-metre performance in conditions where commercial receivers with live corrections deliver multi-metre errors.
The company’s new Precise+ software-defined receiver was put to the test at Thetford Forest, a standard reference environment for GNSS performance under dense foliage. Precise+ delivered 80 cm accuracy at the 99th percentile — positioning error stayed below 80 cm across 99% of measurements in the most challenging conditions on the route. In the same conditions, state-of-the-art receivers produced errors exceeding 3 metres.
The Precise+ results are pure receiver-level performance. No inertial sensors, dead reckoning or sensor fusion were used. This is a like-for-like comparison against competitor GNSS solutions, which means the gains Precise+ delivers compound with whatever integrators choose to apply on top, including sensor fusion, RTK, or PPP corrections.
“RTK and PPP deliver centimetre accuracy in open sky but degrade sharply where signals are disrupted by tree cover, buildings or multipath,” explains Scott Pomerantz, CEO of Focal Point Positioning. “This limits deployment to a narrow slice of the road network, not the environments people actually drive in. Meanwhile, correction services carry high recurring per-vehicle costs yet cannot fix what happens at the receiver when the signal environment degrades. This means OEMs pay for precise positioning that doesn’t function where it matters most.”
By expanding the operating domain of high-precision GNSS, Precise+ allows OEMs to deploy autonomy and ADAS features confidently across real-world driving conditions, and lets existing investments finally deliver value beyond open sky.
Precise+ is targeted at automotive applications, including ADAS, automated driving and V2X, and is equally applicable to any system requiring sustained high-precision GNSS outside of open-sky conditions.
