The GS-U is the latest small, light-weight and fully waterproof groundstation equipped with an integrated battery pack for portable and mobile application.
Following upon the resounding success of the MTWE in 2013, it will open its gates again from 21-23 OCTOBER 2014. Come and see us at Booth No. 1030.
The world's largest and most important exhibition in the field of hydrometeorology, hydrology, environmental monitoring and related areas. Come and see us at Booth No. 104.
The DFM-06 is our standard radiosonde for most applications. Due to its excellent characteristics and the reasonble costs, it is perfectly suited for synoptic observations or military applications.
It is designed to measure the profile of atmospheric pressure, temperature, humidity, wind speed and direction, from the surface up to 40 km altitude. Continuous data sets of measurements are sent down to the groundstation by a high quality radio-telemetry link.
Its main characteristics are:
Very Low Weight (90 g)
The low weight of 90 grams significantly reduces the costs for ballons and gas.
All sensors are Ready To Fly - completely factory calibrated, no additional ground calibration is necessary.
High-Power Lithium Battery
The power supply is activated by a ON/OFF switch with control LED. No special battery preparation is necessary.
GPS for Wind Finding
A 20 channel GPS module provides most precise position information of the radiosonde which is used for calculating the profile of winddirection and windspeed.
Fast and Easy Initialisation
Prior to launching, a simple cable connection starts up the sonde, sets its frequency and downloads the calibration data for the sensors from its on-board non-volatile memory. During this rapid and simple initialisation phase, the sonde is also checked and tested by the groundstation. The sonde is now ready for immediate release.
Each radiosonde can transmit in a narrow channel anywhere within the meteorological band, which is 400 MHz to 406 MHz. The sonde uses an on-board frequency synthesiser, which is automatically set to the desired transmission channel during initialisation.
High Quality Telemetry
The sonde contains a high specification telemetry transmitter. The radio transmission from the sonde meets demanding radio requirements and can cope with long slant ranges, even as far as 300 km.
All the important functions of the sonde are controlled by an on-board low-power microprocessor. This looks after the sensor measurements and in-flight tests, as well as communication and initialisation.
