Telemetry system of FIK III. Stratospheric balloon

The paper presents design and application of a telemetry system for stratospheric balloon based on Internet of Things System of SigFox. The purpose of the telemetry system is balloon tracking during the stratospheric flight. It was tested on experimental flight of FIK III stratospheric balloon equipped with SigFox as main transmitter and UHF transmitter for backup. The payload consisted of ADS-B receiver, and two independent dosimeters for radiation measurement. The paper presents verification of operation of telemetry system on results obtained during experiment. The end of paper covers also some considerations about advantages and drawbacks of such solution.
