GNSS Reliability Guide
Understanding how space weather affects positioning, RTK, and survey operations
GNSS & Space Weather Basics
- How Space Weather Affects GPS Read now → Solar activity disrupts the ionosphere, degrading satellite signal accuracy and availability.
- GNSS Risk Levels for Operations Read now → Operational risk framework for drone RTK and survey GNSS based on the Kp index and scintillation.
- Solar Flares vs Geomagnetic Storms Read now → Two distinct phenomena with different timelines, causes, and impacts on GNSS receivers.
- What Is Ionospheric Delay? Read now → How charged particles in the ionosphere bend and slow satellite signals, introducing positioning errors.
- GNSS Space Weather Glossary Read now → Key terms explained: scintillation, ionospheric delay, cycle slips, TEC, and the Kp index.
For Drone Pilots
- When Should Drone Pilots Cancel Missions? Read now → Kp thresholds, risk indicators, and decision criteria for go/no-go flight planning.
- Why RTK Drops to FLOAT Read now → Ionospheric scintillation and signal interference cause ambiguity resolution failures in real time.
- Why DJI, Emlid & Base Stations Struggle Read now → DJI RTK drones, Emlid receivers, and NTRIP networks all depend on ionospheric stability — and solar storms take it away.
