METHOD OF DETERMINING AND RECTIFICATION ACCELERATION FROM OPERATION OF SPACECRAFT CORRECTION ENGINES Russian patent published in 2020 - IPC B64G1/24 

FIELD: space equipment.

SUBSTANCE: method relates to space engineering and can be used to increase accuracy of correction of orbital motion of spacecraft (SC) equipped with autonomous radio navigation equipment and operating on reception of radio signals from global navigation systems in the mode of daily trajectory measurements and definitions. In assigning the determination of the control parameter to the maximum possible distance from the application point of the speed pulse (one of the SC orbit nodes), i.e., to the point, where the SC latitude argument is π/2, in fact, the error in determining the control parameter is zeroed by highlighting the instrumental component of the error in determining accelerations (or thrusts of the engines). Lateral velocity impulse at the active section symmetrical relative to one of the nodes is for the working method.

EFFECT: method is aimed at providing acceptable accuracy of determining and specifying projections of control accelerations on reference directions of motion when performing single corrections on the revolution.
