Work in progres, not finished yet

Aerolabo Aérolabo

The idea for Aerolabo originated within the scope of the youth activities DFJW in the balloon sport. In principle, it is no new idea to carry out measurements within the scope of a balloon take-off. Already with the first flight of a manned gas balloon in 1783 were a barometre to the measurement of the atmospheric pressure and a thermometer on board. - however, the today's possibilities of the at a reasonable price available telemetry are new.


Today one could combine, for example, an single-board computer like Rasperry Pi, Arduino, or similar with an enlargement package with the measuring feelers which there are under concepts like sensor Box with a radio module (mobile Internet, ham radio) and produce a data connection about a gateway on the Internet - and data like remote control orders of every point in the world send and receive. And this can be realised in to an amount in the lower three-place area where still few years ago costs would have originated which one could hardly have raised privately. And the Aerolabo would also not weigh any more than the collision-warning lights which we hang under our basket.

Or simply become an airborne station in the AirPi project.

However, the called examples of a possible implementation and construction of an Aerolabo are not meant strictly - leave to your creativity quietly free run, there are not mental bans.

Kick out of vision

Since Canadian students have shot photos from the stratosphere with the help of a weather balloon, have taken as an example to themselves a row of school projects this experiment, and have begun similar projects. So many that there are, in the meantime, commercial suppliers) for the required parts.

Manned free balloons

We are on the move with our hot balloons and gas balloons not completely so high, not in the stratosphere on the edge of the universe, but in the troposphere. But heights to about 6000 metres are absolutely possible - a height already the first German aeronaut, Friedrich Wilhelm Jungius reached. But also in the troposphere there is to discover a lot, and in the troposphere the weather events happen. And to use a manned balloon for a project offers above all an advantage: If a light project, the Aerolabo, in a flight is carried along which is operated anyway, no additional costs originate, the Aerolabo can be taken free of charge. Also an experiment one would like to send later in the stratosphere, if one could test first of all with a manned balloon.


The gas balloon was the Space shuttle for the airspace - the Airspace shuttle of 18. till the 20th century, with him the atmosphere was investigated - how on the Zeichnung5) by H. Largely on top illustrated. Today the manned balloon ride plays no more role in the research, but she could play a role in the area of the education again - get to know by discover.

Idea or project?

Aerolabo is first of all no project, but an idea for projects. Our idea is that the free balloon can be a carrier system of your projects. To make projects from the idea, now it needs your ideas.

From the idea for the project

If her your images have developed for an Aerolabo, it is a matter of examining like it can be brought best of all with the carrier system balloon in the air. We would establish in addition the contact with aeronauts - according to project to gas or hot-air balloon drivers. And if stand desired, in an advisory capacity aside. Further we offer to introduce your projects here on the platform balloonwiki. Further we pursue in our field of work a private Wiki for the internal exchange between the project partners.

Hot-air balloon

The advantage of the hot-air balloons lies in the fact that one can load the complete system including the required heating gas, as a rule propane, on a vehicle, and with it can drive where one would want to start. Worldwide ten thousands take place yearly, maybe also hundred thousands hot-air balloon journeys. Disadvantage of the hot-air balloon is the length of the trip restricted to few hours, and that he changes his surroundings more than the gas balloon because of the distiller and the air generated with it. It is a matter this to consider with all measurements directly or indirectly deal with the air temperature.

Gas balloon

The big disadvantage of the gas balloon lies in the fact that the Traggas necessary to his company is not available everywhere. Though one can transport it, by tanker, but this raises the price of the start extremely. Start places to a gas line are connected there is at the moment only in Germany, and one in Switzerland. Here it goes to the overview of the gas balloon start places.

The number of the gas balloon rides is low worldwide. In Europe still gas balloons might start now and then in Poland and Italy, beyond Europe in Albuquerque and one, two other places in the USA. The annual number of the gas balloon rides might lie worldwide with about 600, of it about 500 in Germany.

Advantages of the gas balloon are his longer length of the trip - from two to three days are possible with suitable weather conditions - and that he influences his surroundings less.

Gas balloon ride

Here as an example journey report, journey distance and height diagramme of a gas balloon ride from Stuttgart to Slovenia. There are more examples in the column journey reports. And as such a gas balloon is driven: Driving theory

Temperature measurements

To measure the temperature sounds easy, nevertheless, in every household there is at least one thermometer. To measure the temperature, however, exactly, without influence from direct or indirect radiation influence, is a difficult underpinned.

The picture shows again the drawing with the basket of the gas balloon Humboldt and his instruments. The Aspirations-Psychrometer and the Aspirations-thermo graph are encircled red. Both are right beyond the basket, so that the measurements take place beyond the area by the temperature of the basket influenced air. Namely the Aspirations-Psychrometer in a rack on eye level to be able to read it during the journey with the help of binoculars. And the Aspirations-thermo graph hangs below the basket.

With the ventilated instruments by which a ventilating fan leads constantly an airflow in the measuring feelers, and which are protected extensively against radiation exact measurements can be carried out. And with the gas balloon 1 metre of distance also reaches aside or down to minimise the influence of the basket on the air temperature. However, with the hot-air balloon is not known in which vicinity he influences the air temperature.

Balloon partner looks

If you already have an idea for a project “Aerolabo”, it is a matter for you of finding a “balloon partner”. If you yourselves nobody know you can ask, you can move up with pleasure to us - then we would look for you for a partner. Easier you contact us about You find other contact data here: Contact

Presentation of your projects

If you deliver material to us, we present with pleasure your projects here on the platform

Contact among the project bearers

In our field of work we have own Projekt-Wiki “aerolabo”. Here one can exchange himself privately, documents deposit, and also collect material for future presentations.

Still questions?

Does not avoid you if you ask have to put this also!

Balloons in use application for the science

Also today balloons are on the move still for the science, indeed, as far as to us famously only unmanned or as chain balloons. Here an incomplete list to us of known projects:

The application most spectacular probably at the moment is the Arctic expedition MOSAIC.

Report on test of a captive balloon of the company Balloon construction Wörner near Torgau for this expedition:

The Arctic stratosphere Report on researches to the ozone layer over the Arctic:

Solar observatory In big height one can observe sky body with only minimum influence of the terrestrial atmosphere:

Cosmic radiation

Tip In the end we would like to point out you still to different activities within the scope of the youth work. Information in the column youth.

1) See Wikipedia article Berliner scientific aviations–> former scientific balloon rides 2) There is also an independent project called scythe box - description on the homepage of scythe box: »senseBox:home a modular environmental measuring station is to build. According to interest or research question citizens can put together to themselves a measuring station with different sensors and connect about LAN, WLAN or LoRa with the Internet. Easy instructions allow the construction and the registration on openSenseMap. Then she delivers continuously place-related (mobile or stationary) measurements to temperature, aerial dampness, atmospheric pressure, density of light, ultraviolet rays or particulate matter load.« 3) Supplier for weather balloons and accessories - information from the Internet, not completely: meteolabor Stratoflights 4) The French Jean-Pierre Blanchard carried out the first successful start of a balloon in Germany on the 3rd of October, 1786 in Frankfurt am Main. Also the following starts in Germany were carried out by him. Only on the 16th of September, 1805 it created Friedrich Wilhelm Jungius as the first German to carry out a balloon take-off successfully. 5) The scientific journey of the balloon “Humboldt” from the 1st of March, 1893 - drawing of H. Largely, becomes in the thesis of Sabine Höhler - aviation research and aviation myth: scientific balloon ride in Germany, in 1880 - in 1910, discussed - see also Google Books.

Sandsack Sac à sable

Scetch of a Sandbag for use in gasballooning. The yellow body is connected with string with the hook. The string is going to the eyes in the top of the sandbag. There is a handle on the bottom of the sandbag to keep it.

The ballast for gas balloons is stored in sandbags. To give out ballast, sandbags are not dropped, on empty them. Theres is a handle on the bottom of the bag, to keep it. There are eyes on the top of the sandbag for the string connecting the bag with a hook.

The picture shows the emptying of a sandbag. The sand is falling toward the earth.

The Balloon Live project started in 2018 as a follow-up project to replace the FAI Balloon Competition Loggers introduced in 2009 by the New Technology Subcommittee. The new project has a larger scope. It replaces the existing loggers by a mobile app and an additional sensor box to guarantee a constant and equal quality of the position (GPS) and altitude (GPS and barometric) measurements. Additionally, the live transmission of the data becomes reality and opens a lot of new possibilities for live coverage and tracking of the competition. is an essential part of the project as platform for data recording, visualisation and scoring.

In August 2019, the New Technology Subcommittee and the Balloon Live Team proudly launched the mobile app on Android and iOS.

The app is used in hot air balloon competition and has the following features:

  • 2 app modes: training and competition
  • Flight recording with Start/Stop functionality
  • up to 8 different electronic marker drops
  • up to 8 goal declaration slots
  • recording in IGC-file format
  • export as IGC-file
  • Automatic flight resume on app restart
  • Background mode when flight is started
  • Connection to external GPS box (available later)
  • In competition mode:
    • Synchronisation of competition settings and flight data from
    • Live tracks to

Along the release of the app, was updated with the new WatchMeFly Comp Center that allows event organisers and competition officials to manage all the flights, tasks and Balloon Live logger data in real time.

Login as a pilot to the Pilot dashboard and have an overview of your past and upcoming competitions. Find your personal token/code to register your Balloon Liveapp to a competition and download all your recorded tracks directly on your personal profile page.

Competition officials can manage competition details, pilot list, flight and task settings, official noticeboard, measuring reports and download all recorded tracks immediately after landing.
