u-blox delivers PointPerfect via mobile internet or L-band satellite signals to any number of end-devices. PointPerfect’s broadcast is on a continental scale with homogeneous coverage in Europe, the contiguous USA, Canada , South Korea, and Australia regions, including up to 12 nautical miles (roughly 22 kilometers) off coastlines. It delivers 3-6 centimeter¹ positioning accuracy with a convergence of just seconds. PointPerfect adopts the industry-driven SPARTN messaging format. SPARTN is an industry-led format that enables the highly efficient transfer of GNSS correction data. It is transparent, and open to any integration partner. This, combined with the lightweight and secure MQTT IoT delivery protocol, results in a real-time, bandwidth-optimized, cost-efficient solution ideally suited for mass-market applications.

PointPerfect and all u-blox services are delivered via the intuitive Thingstream IoT service delivery platform, an enterprise-grade cloud platform proven to support billions of messages. Thingstream provides a self-serve environment where users can manage their device fleet, optimizing cost and performance through flexible and predictable pricing plans. PointPerfect is backed by a full warranty, 99.9% uptime availability, and 24/7 reliability.
