The question of improving the standard deviation of the phase coordinate error, stability, and noise immunity of the rangefinder for information and measurement system of the automated air traffic control of aircraft is considered. Rangefinder state and observation models which consider kinematic and dynamic characteristics of air crafts have been proposed. A rangefinder algorithm has been developed and investigated through simulation modelling on a computer with research results obtained.

The state and observation models considered both kinematic and dynamic aircrafts parameters should be applied for the electronic navigation aids accuracy increasing issue of the air-traffic control system data measuring. In contrast to current air-traffic control system kinematic and dynamic parameters summarizing allows to describe the aircrafts movement model more adequate. In the study the theta-theta (t-t) navigation channel functioning algorithm of the air-traffic control system data measuring constructed by the kinematic and dynamic parameters correlation principle was developed and tested.

The minimum composition of objects involved in the implementation of the developed semi-passive guidance technique is determined. The prospects of implementing the developed technique with a network-centric method of object interaction are indicated. A variant of the synthesis of trajectory control algorithms for all objects involved in the implementation of the developed technique is presented. The potential feasibility of the method is shown when using the measuring instruments available in the onboard control systems of objects. Techniques for improving the accuracy of determining the coordinates and parameters of the movement of objects have been developed and studied.
