The Dropsonda is the latest innovation from Meteomodem’s R&D department. Based on the technology of the M10 radiosonde, the Dropsonda allows to establish a vertical atmospheric profile from the plane level to the ground, measuring the PTU and wind parameters (Direction and Speed) during the descent. The particular design of the instrument ensures consistent measurement and high-quality data transmission in real time.

The Dropsonda sounding system consists of a receiver adapted to aeronautical imperatives (receiver installed on the plane), omnidirectional radio and GPS antennas and finally a software dedicated to these atmospheric measurements.


– Based on M10 probe technology, famous and well-known instrument in the international market and OMM
– Multiple monitoring of probes by the receiver.
– Lightweight and robust with proven efficiency in the field in test episodes in Alaska especially
– Special design of the parachute allowing optimal results in descent
