Description: The analysis of basic tasks is conducted, for the decision of which it is necessary to forecast the trajectory of flight and time of achievement of purpose the guided airballistic vehicle. It is rotined that the task of prognostication of trajectory in a real time scale of flight of Speed maneuvers an airballistic vehicles factor consists of synthesis of algorithms, providing the required exactness of calculation of trajectory. The method of prognostication of trajectory and block of airballistic vehicle hours is developed on the basis of the external trajectory measuring. The got analytical correlations are fixed in basis of the offered method of calculation of the forecast trajectory and block of airballistic vehicle hours.
Keywords: forecast trajectory, airballistic vehicle, point of meeting, block hours
