One of the most common methods for monitoring mobile objects is satellite monitoring. There are a number of factors that complicate the process, the main one being the inhomogeneity of atmosphere, and in cases of insufficient power in the communication line, it becomes impossible to monitor aircraft. Therefore, it is necessary not only to choose the most optimal system, but also to ensure the proper level of transmission, excluding the influence of the ionosphere, which has the greatest impact on data transfer in free space. The article presents calculation of losses in free space for Iridium and Gonets systems. Methods based on the total electron content of the ionosphere are also proposed. Based on the models examined, the effectiveness of the methods for the most suitable communication system was estimated.
