Balloon probe (measuring instrument)

from Wikipedia, the free encyclopedia

As balloon probes are measuring instruments of the meteorology and aerology referred to by a supporting strong balloon be brought into greater heights. They are built for several areas of application:

The balloons have a diameter of between 1 meter and several meters , depending on the payload and the planned flight altitude . As a result of the increasing air pressure , the balloon expands more and more until it finally bursts. Devices with more valuable instruments are allowed to float to the ground with small parachutes ; they have an address to which the finder is asked to return.

The flight path can be measured by analyzing radio signals or optically / photographically. For visual tracking, motorized theodolites and special kinetheodolites were developed in the 1950s , while so-called ballistic cameras have been around since the first rocket tests in the 1940s . The best-known of these camera types is the BC-4 from Wild-Heerbrugg.

Unmanned balloon probes with self-registering measuring instruments have been around since 1890, but in the form of radiosonde only since 1929.

Particularly large or complex balloon probes are often referred to as research balloons.
