“Achieve Centimetre level Accuracy – Instantly, Everywhere”
PointPerfect Flex is u-blox’s cutting-edge PPP-RTK GNSS augmentation service, designed to deliver real-time, centimetre-level positioning with unparalleled coverage, efficiency, and ease of integration.
Why PointPerfect Flex Matters
- Real-time centimetre precision: Combine the best of RTK and PPP to converge to centimetre-level accuracy in seconds, even for mobile or dynamic applications.
- One broadcast, many users: A single correction stream can be shared by many receivers, reducing infrastructure overhead and scaling effortlessly.
- Wide-area, continental coverage: Uniform coverage across large geographies (including up to 12 nautical miles offshore) ensures consistent performance without regional fragmentation.
- Low bandwidth, high efficiency: Uses the SPARTN standard data format to minimize data transmission costs and support battery-constrained or bandwidth-limited systems.
- Flexible delivery methods: Supports both IP (Internet) and satellite L-band channels, plus compatibility with NTRIP for easy adoption.
- Seamless integration & open ecosystem: Works with u-blox’s silicon-to-cloud stack — receivers, hardware, software — yet also supports hardware from other vendors, thanks to its open architecture.
- High reliability: Engineered for 99.9 % availability, backed by expert support and infrastructure resilience.
- Flexible licensing plans: Usage-based options let you scale with your business, without overcommitting to rigid contracts.
Ideal Use Cases
PointPerfect Flex is perfect for sectors and applications where real-time, ultra-accurate positioning is critical:
- Autonomous vehicles & ADAS – lane-level navigation, automated steering support
- Drones & unmanned systems – precise flight paths, accurate geo-tagging, reliable control
- Robotics & automated machines – repeatable trajectories, high positional fidelity
- Precision agriculture – machinery guidance, field operations, resource optimization How It Works (At a Glance)
How It Works (At a Glance)
- The network models GNSS error sources (clocks, orbits, ionosphere, troposphere) across broad areas.
- Correction data is broadcast via IP or L-band to your device.
- The GNSS receiver computes localized corrections from the broadcast model, applying them to its observations.
- You get centimetre-accurate positioning, with fast initialization and no need for a nearby base station
