OVERVIEW

Designed and tested to full military standards and developed specifically for use in surface warships, naval support ships and other vessels. AGIMET employs the latest proven and in-service solid-state meteorological sensor technology to provide accurate measurement of wind speed and direction, temperature, pressure, humidity and other local environmental parameters.

The system, when combined with AGI’s extensive range of repeaters, also provides for distribution and display of Met data as well as other navigational information.

Information is transmitted digitally thus greatly simplifying data handling and, in many cases alleviating the need for dedicated re-transmission. Wind outputs from the sensors are monitored by the MIU and data is continually and automatically selected from the windward sensor. By accepting inputs from the ships navigation system (i.e. log and gyro compass), both true and relative wind speed and direction maybe displayed and provided as an output. Using a dual redundant data bus architecture, the reliable distribution of data is achieved with minimal cabling.

To meet individual ship system requirements, various solid state sensors are available. These range from ultrasonic anemometers, to ambient air humidity, temperature and barometric pressure, sea water temperature and salinity sensor types.

The precise measurement of wind speed and direction is an essential element in weapon and decoy systems control, helicopter and fixed wing aircraft handling, navigation, fuel management, etc.

Traditionally, wind measurement has been achieved using electro-mechanical anemometers - a cumbersome technique subject to inaccuracies, icing, component wear and unreliability, requiring frequent servicing, maintenance and calibration. AGI's fully solid state wind measurement system overcomes these disadvantages.
