Quoting the customer:
“With Vaisala, we need to bring a van dedicated to storing and operating the equipment and it takes two persons to use. Windsond can be operated from the trunk of the vehicle we would bring anyway. On our next field campaign, we will only bring Windsond.”
The experiment carried a muon detector. The external sensor interface of Windsond was used to read each measurement and incorporate it into the Windsond data feed to the ground. Windsond also logged all data using the onboard logging option.
We are now back in Sweden after the MTWE exhibition in Brussels. It was three intensive and fun days. We are grateful for the friendly reception we received. We learned a lot and had many interesting discussions.
Now we will start following up on contacts and new technology. If you are waiting for us to get back to you, please have patience as we have a lot of work to do. Naturally, you’re also welcome to shoot us an email!
We’re now in Brussels for the Meterorological Technology World Expo which lasts Tuesday to Thursday. Everything is set up and we’re looking forward to meeting the visitors tomorrow. If you are there, you’re welcome to come by our stand 7080 to say hi and have a free cup of quality coffee!
Windsond is part of a project by the Swedish university KTH to launch a high-altitude balloon and measure muon radiation.
Windsond is attached to the bigger payload to assist with live position tracking and data telemetry, onboard logging and eventual payload recovery. Windsond interfaces with the custom muon sensor by the newly developed external i2c interface.
The launch can be followed live (in Swedish) at this link:
Good luck with the project!
The balloon reached almost 35km and the equipment was successfully recovered by the team.
The University of Maryland, USA, is now carrying out a crowdfunding campaign to get a Windsond system for their research and education. The campaign is very successful even with eight days left. We are naturally very happy and touched to see the enthusiasm and success of the campaign. It will be great to work with the university to give their students hands-on experience with radiosounding and provide data for their research.
Sparv Embedded is proud to announce we have been awarded a 400.000 SEK development grant from Sweden’s innovation agency VINNOVA. Our project was among the few selected from an unusually large amount of applications. Over 700 applications were submitted from small and medium-size Swedish companies.
Our project regards a novel way of using a UAV for weather measurements, where we also applied for a patent. If successful, this will form a new part of the expanding Windsond radiosonde system, to give users more flexibility when performing meteorological soundings of the lower atmosphere.
Windsond continues to be used in Mexico for big, traditional sky lanterns.
A special adaptation measures both ambient temperature, ambient humidity and internal temperature inside the heated paper balloon envelope. This is used to monitor, track and recover the lanterns but also to develop a model predicting how high and how long the lanterns fly.
This was also reported about in June.
