Abstract
The present invention can be made more lightweight even if a dry cell is used as a power source battery, can supply a necessary voltage at a battery capacity corresponding to an observation time, and can generate a predetermined electromotive force even in extremely low-temperature environments, This radiosonde power source device supplies driving electrical power to an apparatus tor processing and transmitting observation information resulting from, observing meteorological phenomena of the upper atmosphere, and has; a dry cell such as a lithium battery having a rated voltage lower than the driving voltage of the apparatus; and one or more step-up power source circuits that step-up the voltage of the dry cell to a predetermined voltage.
