Hybrid threats, such as GPS interference and cyberattacks, pose significant risks to meteorological data accuracy. These threats can compromise radiosonde data, leading to inaccurate weather forecasts. The Vaisala Radiosonde RS41 — globally trusted as the gold standard in radiosonde accuracy and reliability — addresses these challenges through advanced security features.

Key security features of RS41:

• Multi-GNSS: Utilizes multiple satellite constellations (GPS, Galileo, BeiDou) to improve signal reliability and accuracy, reducing the impact of jamming and spoofing.
• Message Authentication Codes (MAC): Adds a layer of security to data transmissions, verifying the authenticity of received data and preventing unauthorized modifications.

These features enhance data integrity and provide resilience against interference, ensuring reliable weather data collection. Vaisala's tests showed a 60 percent improvement in the altitude that RS41 security-enabled models can reach under GPS interference, without compromising data availability.

Vaisala’s ISO 27001 certification demonstrates that we take every measure to ensure information security, giving you confidence that your operational data is protected at every stage.

Vaisala will be showcasing all RS41’s advanced features, including RS41 E-models with 66% less plastic, and we invite you to visit our booth #A816 to learn more about our uncompromising technology.
