Portable automatic sounding system


JL-TK satellite navigation sounding receiver

Product introduction

Satellite navigation sonde receiver is a multi-channel receiving system developed according to the requirements of the Functional Specification of Satellite Navigation Sonde Receiver issued by China Meteorological Administration. It has the characteristics of good environmental adaptability, reliability and stability, high measurement accuracy, easy maintenance, etc. It can quickly and accurately obtain the temperature, humidity, pressure, wind and other parameters of different sonde deployed in the air by various stations. Equipment for continuous receiving of radiosonde data.

Equipment composition

The satellite navigation sounding receiver consists of a receiver host, an antenna assembly and a structural support.
