METHOD OF AIRCRAFT CONTROL WITH SATELLITE NAVIGATION EQUIPMENT AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC F41G5/00 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to control, in particular to guided weapons, it can be useful in aircraft control systems, shells and missiles, in which the flight trajectory in the initial and middle sections is corrected according to the data of the signals receiver from a navigation spacecraft. To do this, the definition of the current coordinates of the aircraft is duplicated by a second satellite navigation equipment in which the antenna axis of the receiving antenna is rotated about the axis of the receiving antenna of the first satellite navigation equipment by an angle, in which the total radiation pattern of a system of two receiving antennas provides in all directions a directivity factor of at least 0.5, while the number of visible satellites in navigation and the geometric factor of their position (GDOP), determined by the first and second satellite navigation equipment, the level of reliability of navigation information is assessed, and the correction of the flight trajectory of the aircraft is carried out at the current coordinates determined by the satellite navigation equipment with a higher level of reliability. In this case, in the control system of an aircraft, the assigned task is achieved due to the fact that the aircraft is equipped with a second satellite navigation equipment with a receiving antenna, connected in series by a comparison unit and a switch whose output is connected to the input of the on-board calculator, the first output of the first satellite navigation equipment and the first output of the second satellite navigation equipment being connected to the first and second inputs of the comparison unit, respectively, and the second output of the first satellite navigation equipment and the second output of the second satellite navigation equipment are respectively connected to the second and third switch inputs.

EFFECT: technical result is higher reliability of communication between the aircraft and the navigation spacecraft grouping along the entire flight path, providing higher stability of the guidance system.
