» How to register your weather balloon in Germany «
To get your “stratosphere adventure” started, you need a permit for the uplift. Legally, the weather ballon is a so-called “unmanned free balloon”. In Germany the granting of the permit is up to the state in which you would like to start. Therefore, you must apply for the desired permit to the Federal Aviation Authority, and possibly with the German air traffic control. The registration takes place via e-mail, whereby a processing time between two and four calendar weeks should be expected.
In order to give you a head start, we have developed a generator that guides you step-by-step through the registration process. Furthermore, the generator provides some tips and hints*. In the end, you receive an e-mail with all the relevant information for your registration. The only thing which is up to you is to forward this e-mail to the responsible Federal Office of Civil Aviation.

Here you have to enter the exactly coordinates of your launch site (Longitude, Latitude)
To get the coordinates use Google Maps to navigate close to your launch site. A click with the right mouse button opens the context menu. Click on "What is here?". The GPS coordinates are now displayed at the bottom of the screen.
Tip: Within urban areas it can be difficult to get a permit. In general, in more rural areas it's easier to get the permission. It is important to keep a sufficient distance from airports or restricted areas.
Please find out the total weight of your full equipment like cameras, GPS Tracker, styrofoam capsule, parachute, weather balloon, ... To find out the weight in total. If you use our equipment you find detailed information in our online-shop. Please note: to get the permission it is necessary to avoid a weight of more than 4kg in total, that you are classified as light. You get no permission for medium and heavy unmanned free balloons at the moment.
To determine the smallest surface area, multiply the length (in cm) of the smallest surface area by the width (in cm) of the smallest surface area of your probe, for example, the smallest surface area of Stratoflights Polystyrene Probe is 22 cm x 18 cm = 396 cm².
Also the flight duration depends on the total mass, the amount of gas and the used weather balloon. The average stratosphere flight takes about 2.5 - 3.5 hours. Our helium calculator also provides further information.
To get a permission you need a parachute for a safe landing. The parachute will be installed in your overall system as follows: From the weather balloon a special cord leads to the parachute and is attached to the top end. At the lower end of the parachute another piece of special cord leads to your probe. Immediately after the weather balloon plops due to the increasing atmospheric pressure, the parachute opens automatically and your probe comes back to earth softly and safely.
The authorities need a description of your payload packaging: for example the polystyrene probe of the weather balloon kit contains a camera, batterypack, GPS tracker and a datalogger to measure datas frome the Stratosphere.
The weather balloon flies in average about 80 kilometres as the crow flies. The flight distance depends not only on the amount of gas in the balloon but also on the wind speed. On stormy days, the weather balloon can fly more than 130 kilometres as the crow flies, or it can fly a "loop" and land only a few kilometres away. If you take off near another stat, you can include in the description that the route is predicted with the help of the flight path predicting tool of Stratoflights to get a forecast and avoid crossing other states, if necessary, the take-off is postponed to another date so that the weather balloon flies inland.
Please make sure that your payload packaging is safe and that your parachute will work. Our polystyrene probe and our parachutes are made for flights to the edge of space and most authorities know our products.
We only sell high quality and relialbe products. All products are used by ower own for flights to the stratosphere. If you place your trust in us, please use the GPS Tracker TK102-2 or the SPOT Trace. If you use an alternative GPS tracker, please add the corresponding designation here.
ATTENTION: many TK102-2 GPS trackers are available for many times less on the Internet! However, these are usually Chinese counterfeits of the original, which do not work reliably!
