HMP45D with DTR13
Water temperature sensor as an option, measurement included. Installation not easy, must be done in co-operation with the ship owner.
GPSdata for true wind calculation, location and time information
Available from Inmarsat-C radio or separate unit or from ship navigation system, as default taken from Inmarsat radio.
Compass For true wind calculation. taken from ships Gyro compass
in standard NMEA183 format. Own electronic compass not recommended due to calibration requirement (turn around 3660 deg).
Bridge console
Message editing and real-time display , standard Laptop computer.
Inmarsat C terminal
Data transfer via satellite, Synop messages

9. Standard Real-time View
Standard Real-time display
Data updated in real-time
Wind instant every 2 seconds
2 and10 min wind every 30 seconds
Ship data every 30 seconds
PTU data once a minute

10. MILOS520 VOS AWS Synop Editing Measured data updated automatically
Also possible to edit
Manual data
entries
Without manual
data entry auto
Synop is generated
Synop Editing Template
Measured data coming automatically from sensors
Manual data fields empty as a default
All fields editable , also measured data
Quality control in all fields
All calculations and report generation made in AWS, PC-program only the user interface to set in the manual data
Standard editing time 10 minutes
If the data is not edited AWS generates the automatic message from the measured data

13. MILOS520 VOS AWS Communication Inmarsat C as default
Goes, GTS and Meteosat
Argos / SCD
Others
Several communication options available
Inmarsat-C default communication option
Goes/GTS and Meteosat available
Depends on the region
40W transmit power with omni directional antenna
Argos / SCD available
Short messages, only 32 bytes / message
Satellites not continuously available
Argos mainly used in arctic/antarctic regions
SCD available only in south America ( Quite similar to Argos)

14. 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.
Inmarsat-C data reporting mode
Short messages, only 32 byte packets
Cheap to operate, price depends on operator
Due to short messages binary formatting needed
Receiving station must be tailored for the binary protocol
In use in Australia:n Met Bureau VOS application
Application built in co-operation with Vaisala Melbourne
