Relative Humidity & Temperature

In both systems there were reception problems, probably due to an issue in the radio emissor of the radiosonde or a bad reception on both radio antennas because some connectors of the signal amplifier were replaced, also the Skysonde system reception is worse than Imet system.

Ascent rate

For this launch the helium pressure was increased from 300 to 500 PSI, for this reason the ascent rate also was increased to 4.5 m/s which is an acceptable ascent rate.
