The goal of modern artillery is to increase precision and reduce the time it takes to calculate the firing elements in order to be able to act as quickly as possible. Factors that affect the trajectory of the projectile are meteorological influences that, depending on their values, can affect the accuracy of hits. Artillery shooting is described throughout the paper, as well as topographical and meteo-ballistic corrections, and the calculations of which firing tables are required. The standard atmospheres for which the firing tables were made and their standard values are also described. Further on, the paper describes the weather bulletin system together with its parts and the meteorological message it sends, which is defined according to STANAG 4082. A program was also created that reads meteorological data from the received meteorological message and outputs atmospheric values for the requested height. The idea of the work is to emphasize the importance of digitization and to show by comparison the speed and time savings when using digital programs.
