METHOD OF CHANGING OBSERVATION AREA ON THE EARTH'S SURFACE Russian patent published in 2024 - IPC B64G1/10 

FIELD: cosmonautics.

SUBSTANCE: invention relates to space engineering, specifically to methods of changing the area of observation of the earth's surface by satellites. For this purpose, using the spacecraft propulsion system, simultaneously create transversal jet acceleration and radial jet acceleration, defined by formula , where ΔV is the difference between the speed of the spacecraft and the orbital speed, R is the radius of the quasi-synchronous orbit, μ is gravitational parameter of the Earth. Argument of spacecraft latitude is changed due to difference of spacecraft speed from orbital speed, wherein spacecraft is kept in quasi-synchronous orbit by radial jet acceleration. By the moment of achieving the required change in the argument of latitude, the difference between the speed of the spacecraft and the orbital speed is reduced to a zero value by creating a reverse transverse jet acceleration, wherein radial jet acceleration is reduced to zero in compliance with the above formula and engine is switched off.

EFFECT: faster change of the observation area on the earth's surface.
