Functionalities
 Automatic acquisition of meteorological data at exposed
positions at sea
certified according to DIN ISO 9001:2000
 Supply of meteorological data for national and international
programs and models
Forecasts 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 AWS
central point of star shaped cabling
 Collects and processes sensor and NMEA data
I/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
