Parachutes for Meteorological Balloon Launches

Parachutes play a crucial role in meteorological balloon launches by ensuring the safe and controlled descent of payloads after balloon burst. They help slow down the payload’s return to Earth, minimizing impact and ensuring data integrity.

PAWAN offers a range of parachutes designed for different payload types:

  • Radiosonde Parachute PX-R1
  • Radiosonde Parachute PX-R2
  • Ozonesonde Parachute PX-O1
  • Ozonesonde Parachute PX-O2
  • Heavy Payload Parachute PX-O3


PX-R1 and PX-R2
are ideal for radiosondes and smaller payloads, while PX-O1 is designed for ozonesondes. For larger ozonesonde packages or custom payloads, PX-O2 and PX-O3 provide the necessary support.
