Benefits
- High degree of automation of measurement, processing and transmission of information
- Transmitting weather information to consumers via wireless (VHF, GSM or satellite) communication channels
Principle of Operation
The principle of operation is based on the conversion of meteorological parameters into electrical signals then in digital codes that are subject to subsequent processing, storage and transmission through communication channels to consumers. It is installed on the sea surface in the coastal zone.
The surface buoy is equipped with as follows:
- meteorological sensors (wind speed and direction, atmosphere pressure and air temperature)
- flashing beacon
- communication channel antennas (GSM, satellite and VHF)
- GPS-GLONASS antenna
- solar batteries
It includes a hydrological unit mounted on a wire-cable at a depth of 30-50 m, which measures as follows:
- water temperature
- water salinity
- flow speed and direction
- hydrostatic pressure
Configuration
- Wind speed and direction sensor
- Air temperature sensor
- Atmospheric pressure sensor
- Hydrologic apparatus
