Abstract An ascentmeter with a sensitivity of 1 cm/s was applied to the automatic control of balloon altitudes. In the flight tests made in 1980 and 1981, the automatic control system was successfully operated to keep a balloon altitude constant during sunset or to descend a balloon with a constant speed.
