What Is PPP-RTK?
PPP-RTK combines Precise Point Positioning (PPP) with Real-Time Kinematic (RTK) correction techniques to deliver centimeter-level accuracy without requiring a local base station. It represents the convergence of two previously separate GNSS positioning methods.
How PPP-RTK Works
PPP-RTK uses satellite-delivered or internet-streamed corrections that include orbit and clock corrections (like PPP) plus ionospheric and phase bias corrections (like RTK). This enables fast convergence to centimeter accuracy over wide areas. The Septentrio mosaic-G5 supports PPP-RTK through Galileo HAS and commercial correction services.
PPP-RTK vs Traditional RTK
- No local base station needed
- Works across entire regions without setting up reference stations
- Convergence time: 30 seconds to 2 minutes (vs instant for RTK)
- Accuracy: 2-5 cm (vs 1-3 cm for local RTK)
- Ideal for: Large-area surveying, remote operations, cross-border flights
PPP-RTK for UAV Operations: Benefits
- Eliminates need for base station setup in field
- Enables seamless operations across large geographic areas
- Reduces equipment cost (no radio link for corrections)
- Works in areas without cellular coverage (via satellite delivery)

Frequently Asked Questions
What accuracy can I expect from this GNSS solution?
Septentrio GNSS receivers deliver 0.6 cm + 0.5 ppm horizontal and 1.0 cm + 1 ppm vertical accuracy with RTK. The exact performance depends on satellite geometry, atmospheric conditions, and correction data quality.
Does this work with ArduPilot or PX4 flight controllers?
Yes. Septentrio receivers output SBF protocol which is natively supported by both ArduPilot (GPS_TYPE=9) and PX4 (GPS_TYPE=9). Simply connect the UART interface and configure the GPS parameter for plug-and-play operation.
Can I use this receiver without an RTK base station?
Yes. You can use NTRIP corrections via a cellular connection, or use Galileo HAS (free satellite-delivered corrections on supported modules). For post-processing, the receiver logs raw data for PPK processing.
