Challenges to national defence in contemporary geopolitical situation

The knowledge of basic meteorological parameters is crucial in terms of understanding the atmospheric behavior for a given period and consequently also for creating the weather forecast. There are several ways of obtaining such data. A broadening of measurement techniques through the unmanned aerial vehicles (UAV) is one of the newest trends of today. Depending on the character of use of the unmanned platform, it could gather data from a significant part of low troposphere. Our experiences and problems with meteorological application of UAV is described in this paper.
