200WX WeatherStation® Instrument for Weather-Monitoring Applications

Airmar's WeatherStation 200WX is the best choice for mobile, land-based, weather-monitoring applications. Sensor-rich, in a durable, rugged, small housing that is IPX6† rated, makes the 200WX ideal for dynamic platforms such as agricultural tractors, weather chasing vehicles and military vehicles.

Being aware of the Dynamic True wind speed and direction is important and often mission-critical. The 200WX calculates the Dynamic True wind speed and direction based upon the Apparent wind, speed of the vehicle, and vehicle heading. Apparent wind is the wind you would feel on your hand if you held it out while moving. The 200WX has internal 10 Hz GPS and three-axis electronic compass that provide the heading, position, speed-over-ground, and course-over-ground functionality that is necessary for Dynamic True wind-data processing on a moving vehicle. 

The 3D compass with dynamic stabilization provided by the three-axis rate gyro enhances compass accuracy in heavy pitch and roll conditions. The patented 200WX maintains dynamic compass performance in hilly and mountainous terrain—common in military situations.
