Sounding Systems and Radiosondes

Our sounding systems and radiosondes are tuned to deliver high-precision atmospheric profiling starting at ground level and going up past altitudes of 36 km. If your operation needs manual release of single sondes or you are running a fully robotic 60-launch automated setup, our product line sort of spans the whole range of upper-air observation needs.

Description

Product Overview

All systems are built around satellite based wind finding (Beidou/GPS), so you get dependable wind profile data plus temperature, humidity and pressure measurements as well, across the troposphere and into the lower stratosphere.

Features

Radiosonde

Application Fields

National & Regional Meteorological: Networks help with regular upper-air observation timings for weather analysis , for initializing numerical weather prediction models and for routine climate monitoring. The automated setup also allows a low-cost growth of upper-air station networks into places where manning is impractical, kind of.
Remote & Unmanned Observation Sites: In mountainous regions, deserts, islands, and border frontier areas, there often isn't enough infrastructure for staffed sounding stations. The automatic sounding system plugs these network holes by running 24/7 without people stationed there.
Civil Aviation Provides wind-profile and atmospheric structure information to support flight planning, route optimization and aerodrome weather assessment.
Military & Special Operations Weather: Support Delivers upper-air meteorological data on demand for mission planning ,and for operational weather assurance in forward-deployed locations or quickly created field positions.
Environmental & Pollution Monitoring: Tracks how atmospheric pollutants travel along trajectories and how vertical diffusion unfolds, for environmental impact assessment and emergency response.
Agricultural & Hydrological Services: Supports agrometeorological monitoring, flood forecasting, and watershed management by continuous upper-air atmospheric profiling.
