The KTMS3630 is a GPS-enabled PTU (Pressure, Temperature and Relative Humidity) radiosonde suitable for day and night operation. It weighs-in at an industry leading 120g and sports agile temperature, humidity and pressure sensors. Temperature sensing is by way of a precision RTD and humidity sensing by state of the art capacitive low-temperature humidity sensors. Pressure sensors use MEMS-based fast responding technology for high resolution measurements down to almost zero pressure. A high-altitude GPS receiver provides complete GPS synchronized time stamps for the data as well accurate position, velocity and heading information. The GPS altitude and pressure altitude are simultaneously available in the KTMS 3630.
The data transmission subsystem is an ultra stable narrow band radio with MSK (low index FSK) operating in the Indian Meteorology band of 400 to 406MHz. Frequency, PSK and Gaussian (i.e. shaped) spectra are available as customizations to large volume customers. The transmission includes complete two-tier forward error correction for error-free data communication. Telemetered information comprises air temperature, relative humidity, pressure, GPS synchronized time, latitude, longitude, altitude, speed and heading, internal electronics temperature.
The KTMS-3630 is designed for long shelf and mission life. Prelaunch calibration, if required, is possible and easy with the available radiosonde calibration station of Komoline. However, the sonde is designed for a shelf-life of close to 1 year without any requirement of recalibration. At 6 to 7 hours of mission life the unit can take some of the longest balloon flights and still have enough steam to transmit data almost to the moment of impact.
