Solution to meet your challenges
Vaisala AviMet AWOS Automated
Weather Observing System
Vaisala AviMet Automated Weather
Observing System (AWOS) is a fully
configurable airport weather system
that collects, processes, and visually
displays meteorological data.
The AWOS help pilots and aviation
personnel make critical decisions
by providing continuous, realtime reports on airport weather
conditions. AWOS weather reports
are availed to airport personnel via
workstation displays and various
interfaces to the other airport
systems.
In addition to measuring basic
weather parameters, the AWOS can
be customized to detect lightning
and runway surface condition, and
also the more problematic weather
phenomena such as wind shear.

workstations
A typical Vaisala AviMet AWOS consists of the field sensors, central data unit(s), communication interfaces and different workstation
types.
System overview
A minimum installation of Vaisala
AviMet AWOS consists of sensors,
communications equipment, and
one Central Data Unit (CDU) which
works also as a workstation and
runs the software applications. The
minimum system can be expanded
without any limits to the system size.
Components of a typical AWOS:
 Central data unit (CDU) with
housing
 Communications equipment
 User workstations
 Remote Control and Maintenance
workstation
 Digital displays
 Printers for data and alarms
 Field sensors, associated power
and signal cabling, and installation
accessories
 UPS for the Central Data Unit(s)
All critical functions of the system
can be duplicated to ensure
uninterrupted flow of data.
Software architecture
The AWOS software consists of the
Central Data Unit (CDU) software
and the workstation software.
The CDU software performs main
operational tasks, and monitors and
controls the system.
Central data unit
The CDU is the main computer
which collects data from the sensors
and performs meteorological
calculations, generates ICAO defined
aviation reports, and continuously
carries out diagnostics of the
incoming data and the entire system
itself. The CDU also stores the
measured and calculated data as well
as the transmitted reports.
Workstations and
displays
The number of workstations depends
on the system configuration. Each
workstation has a preconfigured
workstation environment.
Workstations can be used by any
authorized user, but the set of
applications are determined by the
user rights, which are managed by a
user policy.
The commonly used workstation
set-ups are: Observer workstation,
Forecaster workstation, Weather
View workstation, and Remote
Control and Maintenance

workstation. Several display options
are available and they can be
configured to each users preference
and needs.
Seamless integration
The AviMet systems open software
and system architecture ensure
smooth integration of meteorological
data into any ATC, airport-wide
service and maintenance systems,
and other meteorological systems
an airport may have. The AviMet
software runs on Windows
environment.
Communication methods
Vaisala AviMet AWOS is designed
to interface by various output
communication formats and to meet
various communication standards
and conventions.
Database
The Vaisala AviMet AWOS system
can contain a relational database
for data storing which enables the
generation of SYNOP and CLIMAT
reports. The users interrogate the
data using SQL queries, and the
numerical data, generated reports,
and graphs can be stored or further
distributed.
