Shipboard weather systems are used to improve the frequency and accuracy of global weather observations at sea. These observations are used primarily for weather reporting, but can also gather information for oceanography, marine pollution, and weather forecasting.
The Voluntary Observing Ships’ program (VOS) is an international initiative by which ocean-going ships are recruited by National Meteorological services to record and transmit shipboard weather. In order to improve VOS data collection, AXYS and Environment Canada jointly developed the Automatic Voluntary Observing Ships System (AVOS). AVOS is an automated weather station that transmits VOS program reports.
The AXYS Ship Sentinel™ is a self-contained and fully automated weather station that can be installed on new vessels or retrofitted to existing ships. Typical sensor configurations provide GPS position, 3 hourly ship speed made good, course made good, true wind speed & direction, barometric pressure, air temperature & wet bulb and sea surface temperature. Bridge crew can view the environmental information in real time, while various telemetry choices are offered if the data also needs to be sent to a remote location.
