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

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

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

MILOS520 VOS AWS Synop Editing & Real-time Display Synop editing and real-time display running in standard laptop computer Laptop normally located in the Bridge

MILOS520 VOS AWS High Data Quality High quality sensors Measurement validation Min / Max check Step limit check Calculation validation 80 % of data requirement Validation for manual inputs Data Quality control Sensors High quality sensors with calibration Measurements Min / Max check Step limit Calculations 80% of the data required for statistics All values must be legal for the reports Manual inputs

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)

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 BBXX VLST 24174 99383 31448 46/// /0124 10118 20094 30202 40233 52008 22224 85105 BBXX VLST 24184 99381 31449 46/// /0123 10117 20088 30203 40234 52010 22284 85101

Precipitation detector or Precipitation sensor - Data output for Ship systems (NMEA format) - Digital Displays DD50 , WD30, WD50

MILOS520 VOS AWS YourVIEW optional real-time View Optional Real-time Display Real-time display for Ship officers True and relative wind information in same view Ship image following the compass direction Status information of the sensors and connections Data storing in Spreadsheet format (excel compatible) Data output in AWS as default, YourVIEW PC program as an option , requires own PC or at least own serial line in one PC

MILOS520 VOS AWS Future options: CO2 measurement Infrared sea surface temperature measurement In future ? CO2 measurements can be needed Will be available when suitable sensor is available IR sea surface temperature measurement ? Might be one possibility to measure the surface temperature straight from the same mast. No timetable available, under investigations at the moment.

MILOS520 VOS AWS - CONCLUSIONS Based on proven Milos Series AWS and Vaisala extensive experience with Ship AWS Applications Modular hardware and software for high flexibility FM13 (synoptic) and IMM-2 (climatological) reporting Easy Installation - AWS and sensors on 4m tiltable mast (except for water temperature sensor) Varied telemetry options Expanded sensor monitoring capability for additional and future sensors
