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?
Weather balloon 800 Weather balloon 1600 Weather balloon 2000 Weather balloon 3000
Payload up to: 800g Payload up to: 1600g Payload up to: 2000g Payload up to: 3000g
Maximum height: 30.000m Maximum height: 36.000m Maximum height: 38.000m Maximum height: 40.000m

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.

Diameter: 107cm 120cm
Weight: 70g ca. 80g
Payload: up to 800g 800g – 2500g

GPS Tracker: Location of your probe
The GPS tracker is responsible for locating your equipment and preserving your video footage. A reliable GPS tracker is therefore crucial for the success of your space mission. We provide you with two different systems that can be used individually or in combination:

GPS Tracker STRATOfinder

GPS Tracker STRATOfinder:
The GPS tracker STRATOfinder was developed by Stratoflights especially for stratospheric flights. The position data of the STRATOfinder can be retrieved in real time via the free Stratoflights app and thus your stratospheric probe can be located precisely and reliably within 5m.
All you need is a standard SIM card with mobile data. The GPS antenna built into the STRATOfinder is three times larger than comparable GPS devices and thus ensures the best possible security even in difficult regions and mobile phone holes. To navigate to the landing site, simply use the route function integrated in the Stratoflights app.

SPOT Trace: Especially in very extreme regions such as high mountains or the open sea, there is usually hardly any or no mobile phone network available. The GPS tracker SPOT Trace works independently of the mobile phone network and is a real survival device. The SPOT Trace communicates directly with the GPS satellites and transmits its position data almost in real time, even during your stratospheric flight!

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 STRATOfinder works:

Space Cam Apeman

Space Cam “Apeman”: Reliable camera for a weather balloon flight
Most available cameras are not suited to the extreme conditions of the stratosphere. Even large, well-known manufacturers have problems producing a camera that reliably captures the spectacular view from the edge of space in the stratosphere. One reliable camera for stratospheric flight is the Space Cam “Apeman”. The compact action cam is robust, lightweight and captures impressive footage from the edge of space for you with its video settings and image quality. The built-in image stabilizer also creates smoother footage, so you get impressive video of the dark of space and the blue of our earth.


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. To ensure that your camera actually films recordings from 40,000 metres and the entire landing, you need a battery pack that works reliably in this extreme environment and supplies sufficient energy. For this purpose, we provide you with a high-quality and reliable batterypack. Only high-quality materials are used for the Batterypack, which is developed and produced in Germany and therefore differs significantly from conventional batterypacks that everyone has at home as a promotional gift or from the supermarket. Thanks to its high-quality battery cells and good insulation, our Batterypack provides your camera with reliable energy even in the extreme environment of the stratosphere, so that your camera records the 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 STRATO4 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.
