P-band Radiosonde

Description

Developed with satellite navigation wind-measuring technology, our P-band radiosonde is a lightweight observation terminal carried aloft by weather balloons. When paired perfectly with matched ground receiving equipment, it can steadily collect full-set meteorological parameters including temperature, air pressure, humidity, wind direction and wind speed. From near the ground all the way up to 36 kilometers high in the sky, and covering an effective detection distance up to 200 kilometers, it reliably captures complete and authentic atmospheric change data for all-round upper-air field observation work.

Features

It boasts a compact, lightweight build that cuts down carrying load significantly, making it easy to set up and fully adaptable to all regular weather balloons for smooth field launch operations. Fitted with upgraded temperature, humidity and pressure sensing modules, these high-performance sensors maintain steady and precise readings all the way during balloon ascent, ensuring consistently reliable and high-quality observational data at every atmospheric layer.

Application fields

In daily meteorological work and public weather services, it supplies layered atmospheric field data that underpins routine upper-air surveys, weather situation analysis, numerical forecast model operation and real-time early warning against extreme weather events.

For atmospheric science research initiatives, it offers highly accurate temperature, humidity, pressure and wind readings covering the entire troposphere and lower stratosphere, laying solid data foundations for boundary layer exploration, atmospheric dynamic mechanism analysis and professional radiosonde calibration tests.

Within civil aviation scenarios, it feeds authentic wind field and vertical atmospheric structure information to assist airports and along-route weather stations in arranging flight schedules, optimizing flight paths and completing reliable on-site meteorological risk evaluation.

It also serves agricultural production effectively. By collecting meteorological indicators at different heights, it facilitates farmland climate tracking, crop growth protection and timely pre-warning of various agricultural meteorological disasters.

In hydrological monitoring fields, the obtained upper-air meteorological information provides solid reference basis for rainfall trend judgment, flood risk prediction and standardized watershed resource management.

Beyond that, it can clearly sort out the vertical distribution state of atmospheric flow layers, helping researchers simulate the spreading rule of air pollutants, assess regional ecological changes and work out practical response plans for unexpected environmental incidents.

Why Choose Our P-Band Radiosonde

This series of sondes features flexible satellite positioning solutions to suit diverse field usage demands. Its Beidou and GPS dual-navigation version taps into two satellite systems at the same time, offering backup positioning capacity to keep wind observation going steadily even when signal quality of one satellite system weakens in complex field surroundings. We also provide a pure Beidou positioning model that operates fully free from GPS signals, perfectly fitting application scenarios that require exclusive use of domestic navigation resources. Rather than relying merely on ideal lab test results, its wind measurement precision is verified through repeated actual balloon launch experiments, so the indexed data truly matches real onsite working conditions. When it comes to air pressure detection, it adopts graded precision standards according to different atmospheric layers, keeping the error within ±1.0 hPa in conventional altitude areas and narrowing it down to ±0.5 hPa in key high-altitude zones, which fully satisfies the high-precision data needs for troposphere and lower stratosphere research. Thanks to its compact and lightweight structure, it can be easily mounted on all standard meteorological balloons ranging from 300 grams to 750 grams, fitting seamlessly into existing observation procedures. Furthermore, it is well tailored to pair with P-band ground receiving devices, achieving smooth signal transmission and stable high-quality data output throughout the whole upper-air sounding process.
