Functionalities
Automatic acquisition of meteorological data at exposed positions at seacertified according to DIN ISO 9001:2000
Supply of meteorological data for national and international programs and modelsForecasts of various institutions (DWD, BSH, WSA, HPA, ...)
Data is routed into GTS for EUMETNET, NMS, ...
Data can be used as reference for satellite soundings
Supply of meteorological data onboard (for Scientists)proprietary NMEA 0183 telegram

MILOS – System Overview
Central Unit (MILOS)
Sensors (wind, temperatures, humidity, pressure)
Extra sensors (sunshine, visibility)
NMEA Source (position, movement, heading)
DCP (satellite communication)
PC (visualisation, acquisition of visual observations)

Datalogger MILOS
Central unit of the AWScentral point of star shaped cabling
Collects and processes sensor and NMEA dataI/O: analogue, digital, serial
Generates permanent data output (for scientists)floating 1-min mean values
Provides data for visualisation (PC on bridge)current values and graphical trends
Generates FM-13 SHIP (hourly)weather report, sent via DCP

Future Plans
New stationssome new ships in pipeline – Schwedeneck, Sonne
Conversion of fixed Stations to ShipsFehmarn Belt and Bake Zulu will be converted to Ships (FM-13)
Milos replacementsee TT-AWS, TT-on-T
High Datarate DCPswill be introduced in ?
more data, more often, binary data possible
