The Vaisala DigiCOR A® Sounding
System MW31 is a sounding receiving
station for meteorological and
defence applications. It provides
meteorological prole data for
artillery ballistic preparation and
numerical weather prediction
models. In addition, the atmospheric
prole is useful for e.g. for aviation,
CBRN and naval applications.
The Vaisala DigiCOR A
System MW31 integrates the control
of sounding, archiving of sounding
data and the coding of meteorological
messages. Automated data handling
and a variety of interface options
make the message transmission easy
in all conditions.
Meteorological parameters are
measured by a radiosonde attached
to a free ying balloon. Pressure,
temperature and humidity are
measured by the sensors integrated
in the radiosonde. Wind speed and
direction is determined by means of
GPS navigation satellites, optionally, a
radiotheodolite can be connected to
the system.

Sounding
Portable and easy
to deploy
The MW31 for defence has a rugged
laptop and it can be equipped with
a portable antenna set designed for
eld conditions. The MW31, with
its peripheral equipment, is easy to
transport, and quick to deploy. Only
one person is needed to operate it.
The transportation cases are made to
carry the MW31, a few radiosondes,
balloons and other necessary
equipment.
Optional graphical tools
The optional METGRAPH software
module provides you with graphical
presentation of meteorological data.
