Focal Point Positioning, a U.K.-based developer of GNSS-enhancing software, has launched Precise+, a technology designed to deliver reliable high-precision positioning in environments where conventional carrier-phase tracking struggles. The company unveiled the technology at the 2026 European Navigation Conference in Vienna, Austria.
Precise+ extends the capabilities of the company’s patented Supercorrelation platform into the carrier-phase domain, targeting the cycle slips that can cause real-time kinematic (RTK) and precise point positioning (PPP) systems to lose lock in difficult environments.
Continuous carrier-phase lock is required for centimeter-level positioning. In dense urban areas, under tree cover and in multipath-heavy environments, interruptions can trigger cycle slips and force systems to reinitialize. According to the company, these disruptions remain a major obstacle for advanced driver-assistance systems (ADAS), automated driving and robotics applications.
Focal Point said Precise+ improves GNSS performance in challenging conditions, delivering sub-meter accuracy in scenarios where commercial receivers using live corrections typically produce multi-meter errors.
The company tested its software-defined Precise+ receiver in Thetford Forest, a common benchmark environment for GNSS testing under dense foliage. According to Focal Point, the system achieved 80 cm accuracy at the 99th percentile, meaning positioning error remained below 80 cm for 99% of measurements collected in the most difficult sections of the route. The company said competing state-of-the-art receivers produced errors greater than 3 m under the same conditions.
Focal Point noted the results were achieved using only receiver-level performance, without inertial sensors, dead reckoning or sensor fusion. The company said the improvements can be combined with additional technologies such as sensor fusion, RTK or PPP corrections.
“RTK and PPP deliver centimeter accuracy in open sky but degrade sharply where signals are disrupted by tree cover, buildings or multipath,” said 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,” Pomerantz added. “This means OEMs pay for precise positioning that doesn’t function where it matters most.”
According to the company, Precise+ is designed for automotive applications including ADAS, automated driving and vehicle-to-everything (V2X) systems, as well as other applications requiring sustained high-precision GNSS performance outside open-sky conditions.
