  • Specification

Summary

GPS Radiosonde Sounding System, a spin-off product based on WMO-recommendations compliant upper-air system, is designed for limited function version for academic researchers. The selected functionalities enable price performance breakthrough.

This lightweight and compact sounding system is intended for increased portability and conveniences in sounding. Your sounding experiences will be extended more than ever. The corresponding GPS radiosonde, RS-06G(S) carries a temperature sensor and humidity sensor. Pressure is calculated from the GPS altitude measured by single point positioning. Sounding duration lasts 240 minutes, allowing vast stretches of sounding possibilities. Abundant choices of interfaces expand the use of supplemental sensors.
