METHOD FOR CORRECTING THE ORBITAL MOTION OF A SPACECRAFT Russian patent published in 2022 - IPC B64G1/24 

FIELD: space technology.

SUBSTANCE: invention relates to the motion control of a spacecraft. In the proposed method, corrective accelerations (a_i) from the operation of correction engines (CE) are determined using telemetry information (TMI) from the spacecraft orientation and stabilization system. Before the CE is turned on, averaged (by the number of information sources) data on angular velocities of ω_j1 in j-th channels are obtained from the TMI (from astronomical instruments and/or a gyroscopic unit): roll, pitch and yaw. As a result of the test or corrective action on the spacecraft, the working i–th CE from the TMI receive similar speeds of ω_j2 and determine by the differences (ω_j2 - ω_j1) the average rotation speed ω_2i of the spacecraft due to the operation of only the i-th CE. This velocity ω_2i is redefined at the nominal (for this spacecraft) time interval and is brought to it when operating only in test mode, from where ai is then determined by their test values. Based on the results of working out correction plans, a set of reliable averaged acceleration values is obtained for further work with the spacecraft.

EFFECT: universal method for determining accelerations from the operation of CE of various classes, with the clarification of accelerations according to TMI data for the past time periods.
