What the Whitepaper covers -
Understanding ionospheric disruption
Learn what causes ionospheric group delay and scintillation — and why they're an unavoidable challenge for every GNSS user, at every latitude
Multi-band hardware as your first line of defense
See how all-band signal tracking on the u-blox X20 platform maintains positioning stability when single-band receivers lose lock
Real-time corrections that go beyond standard models
Discover why standard ionosphere models only remove 50–70% of error, and how PointPerfect corrections compensate for over 95%

- Why the current solar cycle is making ionospheric disturbances more frequent and severe
- How ionospheric group delay and scintillation each degrade GNSS accuracy in different ways
- Why multi-band receivers outperform single-band solutions under scintillation conditions
- How PointPerfect's real-time correction network stabilizes positioning through active ionospheric events
- Real-world performance data from South America — one of the most ionospherically challenging environments on Earth
