Abstract. The required accuracy in determining the absolute coordinates of combat aircraft during the flight is units of meters. Various scenarios for the combat using air-to-surface missiles based on the technologies of the global radio-navigation satellite system – GLONASS / GPS (GNSS) are possible. The article solves the urgent task of synthesizing trajectory control algorithms that are the best in accuracy and economy for the radar-satellite guidance system of air-to-surface missiles. Only the data of GNSS receivers combined with a small-sized strapdown inertial navigation system of medium accuracy are used as parameters of the rocket position in space (including components of speeds and angles). The accuracy of guidance systems operation depends a lot on the accuracy of estimation (measurement) of phase coordinates used in trajectory control. It must be emphasized that improving the accuracy of measurements is a laborious and expensive procedure. In this regard, the issue of the degree of influence of the errors of various information sensors on the accuracy of guidance is very relevant. This problem was solved in the article by studying the current sensitivity of the information-computer system of guiding the rocket to the accuracy of these sensors.

Key words: radar-satellite guidance system, air-to-surface missiles, ground targets, homing, missile trajectory control algorithm, satellite goniometer-interferometer, pseudo-differential mode.
