METHOD OF EVALUATING THE EFFICIENCY OF DISTRIBUTION OF INFORMATION - MEASUREMENT CHANNELS IN FUNCTIONAL COMPLEMENTS OF SATELLITE RADIO NAVIGATION SYSTEMS.

Abstract

The article analyzes the effectiveness of the management of measurement channels and the method of choosing the optimal plan for the distribution of information flows under changing conditions in the network of the information measurement system, controlling and correcting stations of satellite navigation systems. In the conditions of network operation, when the signal processing time at the switching node takes a certain amount of time, and the importance of information has different values, there is a need to organize queues of requests for information service. The main goal of such an organization is to reduce the loss of information in the network during transmission under the conditions of using transit routes. The dynamic restructuring of the queue at the nodes, in turn, ensures a reduction in the loss of applications due to their "aging" [67]. It was established that a special place in the switching subsystem is occupied by the control system, which controls the collection, processing and further movement of traffic in networks, distribution of network switching resources in accordance with set priorities. It is obvious that the use of dynamic information flow management systems as part of the switching structure will ensure the necessary quality of network functioning, prompt response to low-inertia situations in real time. Dynamic management of flow distribution can be carried out both by managing the network structure by changing the capacity of channel bundles, or by redistributing network channels when changing the information interactions between individual pairs of switching nodes, and by managing flow transmission paths without changing the network structure [60]. It is obvious that the second method is both economically and hardware more profitable, since changes to the network structure are minimal challenge, quality factor, measurement, network, efficiency, state
