Defense meteorology applications

 

Defense forces around the world rely heavily on weather conditions and meteorological forecasts to plan operations and training exercises. In field operations, a superior knowledge of weather conditions has always been advantageous. While modern numerical weather models enhance weather forecasting capabilities, immediate, local weather observations are essential to create accurate weather data reports in support of operational safety and efficiency

Secure & Resilient Weather Data

In modern defense operations, precise weather data can determine mission success or failure. The Vaisala RS41-SGM radiosonde is designed to combat the challenges posed by electronic warfare, GPS jamming, and message spoofing.

Securing your weather data with message authentication

We verify radiosonde messages with cryptographically generated Message Authentication Codes (MACs) to prevent tampering or falsification.

Uses HMAC-SHA256, a widely trusted cryptographic standard

RS41-SGM radiosondes encrypt data, for extra security

Other RS41 models prevent tampering with authentication codes but do not encrypt data
