Background. An automatic dependent supervision (АDS) is the perspective mode in air traffic control. Essence of АDS consists in that the navigation information got from the satellite radionavigation systems (SRNS) aboard an air ship is passed on DTL from an aircraft side in the surface servings as ATM in a digital form. Thus, faultless work of DTL is a necessary condition for functioning of АDS and providing of safety of flights due to a quality exchange information. Accordingly, there is a problem of estimation of authenticity of information transfer such system.
Matherials and methods. A perspective method for the decision of this task is the use of statistical information on exploitation of the systems composition of that is analogical to initial. As an auxiliary system it is suggested to use the system, consisting of the elements united consistently, without the presence of any type of reserve (loaded or unloaded) on any of these elements. The basic used mathematical method is a method of the linear programming, id est for this case being of a minimum of function of reliability of DTL from an aircraft side, being a consistentlyparallel structure with the limit of parameters on auxiliary.
Results. The formula of estimation of authenticity of information transfer is got on DTL. Modernisation of the offered method is produced due to the use not alone, and a few ancillariess. Results over of comparison of method are brought with the known methods of estimation of reliability of the systems – methods of plane and rectangle. Drawn conclusion, in what cases the offered method gives more exact estimation.
Conclusions. An estimation of probability of reliable information transfer on DTL by the offered method is more exact, than at the known methods of decision of this task. Estimation of probability of reliable information transfer DTL, got the method, based on introduction of the supporting systems the higher, than anymore we use supporting systems.
