Failure to apply trajectory corrections for weather conditions causes up to two-thirds of the long-range artillery firing error. Using accurately measured and up-to-date weather data, however, an operator can increase the probability of hitting a target in the first round by compensating for the direction, velocity and density of the air masses the projectile travels through. The most eloquent example of this is the means of applying trajectory correction for classical and unguided reactive artillery ammunition.

Whether you operate on a temporary air field or on a large air base, Vaisala offers the optimal and scalable solution for your weather needs.
The Vaisala Tactical Meteorological Weather Observing System (Tacmet) provides full aviation weather monitoring capability with a mobile system, suitable for temporary airfields, heliports and UAV operations. We also offer complete weather solutions for fixed airbase operations – from a single observation point to multiple locations, with capabilities for runway-long visibility determination (RVR).
All Vaisala military aviation systems meet ICAO and NATO requirements as well as WMO recommendations.

The instruments and observing systems provided by Vaisla have long proven their effectiveness on the battlefield, helping to rescue troops and civilian personnel by providing meteorological information at all levels of the chain of command.
In addition, weather data is absolutely necessary for the prompt and appropriate response to CBRN threats by being used as an essential input in dispersion models of toxic substance releases.

Medium and small unmanned aerial vehicles (UAVs) fly at low altitudes and are consequently directly affected by weather. Given the high value of these aerial assets and of the loads they carry, accurate meteorological information is crucial both in mission planning and during take-off and landing.

Proper performance of weapon systems requires accurate atmospheric information. It is also important for improving passive countermeasures.
Vaisala offers a comprehensive variety of shipboard weather observing means, instruments and data collection systems to provide your ship systems with real-time weather data.
