Working on next generation of Windsond and optional add-on

Closing in to 2020, we would like to tell you what we have been up to lately and tell about our availability during the Christmas holidays.

We have been happy with the Windsond S1 model, but we feel that we want to offer an even better radiosonde to the market. That is why we are developing next generation of Windsond, called “S2”. We also mentioned this in the newsletter from earlier this year. The development is still in an early phase, so we can not reveal any release date. We have great faith in Windsond S2 and we are eager to show you the result. Some improvements that S2 will bring:

– Lower weight
– Smaller
– Easier to use
– Quicker GPS fix
– Better battery life
– Adapted for soundings in rain

We have also started evaluating an optional add-on to Windsond S2, called H4, with sophisticated T/RH sensors. With response time of a fraction of a second and possible sampling rates of 10 Hz, this enables data of very high spatial resolution. Active heating can overcome condensation. This also opens up to supporting higher altitudes (maybe 10-20 km MSL).

We will share more information as development continues. Please reach out to us if you have any questions.


The office will be closed December 21st – January 2nd. We wish you all a Merry Christmas and a Happy New Year!
