On the issue of selecting the minimum composition of a specialized software and hardware complex and the time intervals of its operation

One of the methods of compensating for the influence of the radio propagation environment is the use of a DOM adaptive to the current propagation conditions of a mathematical model of the medium in the measuring loop of the radar. The presence of an adaptive model allows us to evaluate the conditions for propagation and to quickly compensate for errors due to refraction. For the current estimation of the refractive index of the propagation medium, it is necessary to measure: when the troposphere propagates in temperature, humidity, and when distributed in the ionosphere, the total electronic content. The need to measure these parameters determines the minimum composition of a specialized software and hardware complex: a weather station and a receiver of spacecraft signals of global navigation satellite systems. Knowledge of the current operating conditions makes it possible to estimate the time intervals for possible deterioration in the quality of these tools. However, in order to take into account the current operating conditions, it is necessary to answer the questions: under what conditions is it expedient to carry out the specified adjustment, at what rate and how often to measure the current environmental parameters. The article analyzes these questions and answers them.
