DBCP 18 Workshop - Martinique / Oct 14-15, 2002
OVERVIEW
• WMO Objective:
• Increase observations over the oceans
• Utilize buoys, floats, and ships
• VOS - Voluntary Observing Ships
• Synoptic data (real-time communication) for
improved forecasting
• VOSClim - Voluntary observing ship data for
improved climatalogical data base (no need for real
time)
• MILOS520 VOS AWS - New Vaisala AWS
configuration for VOS applications

MILOS AWS
• AWS based on Milos Series of AWS over 2000 built from mid-70’s to
present (M200, M500, M520)
First Ship applications during 80’s
• Total Installed base over 85 systems
• Cruise Ships
• Research Ships
• Military Ships
• Fishing ships
• ASAP containers

Communication
• Inmarsat C as default
• Goes, GTS and Meteosat
• Argos / SCD
• Others
DBCP 18 Workshop - Martinique / Oct 14-15, 2002
Inmarsat C Communication
Inmarsat C data reporting mode: Australia VOS
In co-operation with the Australian Met Bureau
• The message reported is a binary subset of the full
ship message.
• The data is sent via Inmarsat C using the data
reporting mode, which reduces the running costs. The
data is sent to the Bureau via the Perth Land Earth
Station.
• The data is decoded within the Bureau and is then
placed on the GTS as a full Ship message.
