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.
We are preparing for the Meteorological Technology World Expo in Brussels in October. So far we received a lot of interest, which is great!
We are also busy developing new options for ground station. New features will include diversity antennas, water-proofing, etc.
Currently the Windsond system is being used at the Kosan Gas Nordic Hot Air Balloon Championship, July 1-5. The organizers release a sonde before each briefing to help the event director Les Purfield (UK) to set the tasks for the upcoming flight. Before the launch period the organizers release another Windsond to provide the latest winds for the 13 competing pilots + 5 Fiesta balloons.
The weather conditions so far have been really good for balloon competition and many pilots state that they are very happy with the Windsond soundings that are being provided by the organizers.
Right now Windsond is being offered at a special price for hot air balloonists. Please contact email@example.com if you are a balloonist and are interested of buying a Windsond system at a reduced price.
