Walker 7080 is an integrated log, wind and weather system that includes a true wind option. Ship’s speed and distance travelled is derived from a Walker electromagnetic (EM) log transducer. Alternatively, log NMEA 0183 serial data may be used. Calibration of the EM log may be performed using ship’s GPS. Wind speed and direction is derived from input relative wind NMEA serial data. A comprehensive range of Walker wind sensors are available. True wind data can be calculated given suitable inputs.

The weather data functions include measurement of barometric pressure, air temperature and humidity by sensors housed in a single tower and water temperature via a sensor installed in a seawater inlet pipe.

This compact, cost effective system takes advantage of state-of-the-art electronics to process log, wind and weather sensor inputs, and outputs serial data on a IEC61162-1 (NMEA 0183) data bus.

Log, wind and weather elements may be specified separately or in various combinations.

​
