The OH3VHH-1 high-altitude balloon flight was a success: the balloon launch was smooth and tracking of the balloon worked mostly without glitches. This post consists mainly of photos, telling the story of the flight from the launch site to the payload recovery. These photos include a large set of high-resolution images from upper atmosphere taken by the Raspberry Pi tracker hardware in the balloon payload.
OH3VHH is the call sign for an amateur radio high-altitude balloon flight organized by Hämeenlinnan Radioamatöörit amateur radio club, call sign OH3AA, in Finland. The primary purpose of the flight is to be a scientific experiment: to test a variety of radio transmitters for tracking the balloon and to record video and photos during the flight.
Latest update: August 3rd 2021
Planned launch time is on Saturday, July 17th between 7:00-8:00 UTC. We will begin flight preparations already at 6:00 UTC. In case we need to cancel the flight because of bad weather, we will attempt to launch the balloon again either on Sunday, July 18th or on Saturday, July 31st.
