Which weather balloon should I choose? What is the purpose of the datalogger? Which is the right parachute for my payload? What a bunch of questions! We help you to put together your best equipment for your mission.

Weather Balloon: The “drive” for your stratospheric probe

The helium-filled weather balloons differ in their size and so do their properties. For example, a weather balloon 800 can carry 800g payload at heights of up to 30,000 meters. A weather balloon 2000, however, is designed for higher altitudes and payloads, so you can hereby send up to 2000g in up to 38,000 meters altitude. To find the optimal weather balloon for you, you should ask yourself the following questions:

  • Payload: How heavy will my probe and equipment be? How many cameras should my balloon carry with it? Do I want to take experiments on board?
  • Hight: How high do i want my probe to ascend?

Parachute: To ensure a smooth descent
For different payloads we provide you with two different parachutes. These differ in their payload. So, the parachute 2500, produced by us, is ideal for payloads between 800g and 2500g, should your camera probe be lighter than 800g, the parachute 800 is perfectly adequate for your mission.

GPS Tracker: Location of your probe
The GPS Tracker locates your equipment and is responsible for finding all your video recordings. Therefore a reliable GPS tracker is crucial to the success of your space mission. We provide you with two different systems that can be used either individually or in combination:

GPS Tracker TK 102-2: This GPS tracker detects it’s location via GPS and then transmits it via the mobile network. Inside the GPS tracker is a standard mobile phone card. If your probe has landed again after about three hours, you can call the number of the SIM card and the position data will be sent to you via SMS. You can directly enter the link into Google Maps and navigate to the landing site.

SPOT Trace: The SPOT Trace can be used especially in regions with bad mobile service. This works independently of the phone network and is a real survival tool. The SPOT Trace works with GPS satellites and transmits its position data in near real time.

Both systems can be combined with each other to ensure the greatest possible security and thus a successful projec. Howeever, in most cases, one of the two devices is sufficient.

This is how the SPOT Trace works:

This is how the GPS Tracker TK 102-2 works:


Batterypack: Provide your camera with enough electricity for the entire flight:
The internal battery of your camera or the commercially available battery packs are not designed for the extreme temperatures of the stratosphere of up to -65 ° C. So, to ensure that your camera actually shoots the pictures from 40,000 meters altitude and the entire landing, we have developed a battery pack, which significantly extends the battery runtime of your camera in extreme temperatures. Our power batteries work reliably in the extreme temperatures of the stratosphere, so your camera records your entire space flight.

Special Cords

Special cord: connect weather balloon, parachute and probe
The cord, which is used to connect your weather balloon to parachute and probe, has to meet certain requirements in Germany. Legislators specify a maximum tensile strength of 230 N here. Our special cord meets all requirements and is therefore ideal for stratospheric missions.

Datalogger: Record your own data of your flight
With the Datalogger STRATO3 you can reveal the secret to the achieved altitude and record further data such as air pressure, humidity, temperature, GPS position and create a 3D flight curve. The data is recorded by the sensor of the datalogger every two seconds and stored on a micro SD card and can be evaluated easily after the flight. If you are only interested in your altitude and at what speed your probe has been on the way, the Datalogger STRATOmini will be enough for you.

Helium or balloon gas: This will lift offyour weather balloon
To fill your weather balloon, you can use either helium or balloon gas. The latter consists of about 95% helium and is usually sufficient for your mission. You can get the gas at gas dealers in your region, but also in DIY chains such as “Hornbach”. The gas must then be filled on the starting day via a cylinder pressure reducer in your weather balloon. You lend the equipment, alternatively we provide a bottle pressure reducer to you.

The worry-free package for a successful mission: the Weather Balloon Kit
The following video presents the contents of our professional set. The Weather Balloon Kit is our all-round carefree package and contains everything, except balloon gas, you need for a successful flight to the stratosphere. As a special extra, the Weather Balloon Kit comes with a detailed manual, which not only guides you step by step through the mission, but also contains some tips & tricks for sensational shots from the edge of the universe.
