High-altitude balloon contest
Challenge Introduction 2
• STM32 in the Sky is a high-altitude stratospheric balloon
contest between 4 engineering schools.
• This challenge is organized by ST’s Microcontroller Division
to strengthen ST’s education and community programs and
to promote wider STM32 MCUs and LoRa-based solutions.
• The CNES (the French agency for Space policy) and
PLANETE SCIENCES are our partners to organize safety
this event and to get all necessary flight authorizations

Specifications
& Rules
While innovation and creativity drive this contest, schools must apply the
following rules and guidelines.
• Develop a scientist experiment in near space
• Use ST products including STM32 and LoRa-based solutions
• Showcasing the STM32 in near space (HD picture…)
• Share results within the community network
• Follow closely safety specifications from the CNES

Landing Forecast 5
• Weather conditions affect the flight
• Tools, such as “cusf landing predictor” are available to predict
main direction, burst altitude, and landing position.

Stratospheric Balloons (HAB) 7
• Helium balloon is the easiest and
cheapest way to “carry” objects in the
near space (Stratosphere).
Ex : Twice a day, WW meteorological stations send
radiosondes this way to predict weather forecast
• A large community of HAB Hobbyists.
WW Amateurs radio, students or simply fans use to
HAB, either to send object, to take HD picture at high
altitude, to test HF transmitter range and new antenna
design, or to beat new technical challenges (record in
high is 45Kms and length with Earth circumnavigation).

Balloon Tracking 8
• Tracking is used for balloons recovery
• HAB telemetry datas including GPS
coordinates are transferred using
LoRaWAN™ technology
The Things Network Map
• Datas are received and decoded by ground
stations (LoRaWAN gateways from
The Things Network –TTN )
• Those datas are then send to an HAB
application server called HABBUB tracker, or
TagoIO to make all datas visible to anyone WW
HABHUB tracker
HAB Application Server 9
HABHUB tracker
Typical flight
• Duration : 3h30
• Max altitude : 30/45 km
• Max distance : 50/1000 km
• External T°c : -60°C

TagoIO (an IoT application server) is our partner to broadcast STM32 in the Sky
event in real-time.
• Access to Habhub tracker, live tracking
• Access to the real time data feeds
• Access to the agenda of the day
• See the school presentations
• Live camera on the Golf
