METHOD FOR NAVIGATION CONTROL OF SPACECRAFT INJECTION ORBITS AND A SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2021 - IPC B64G1/00 G08C19/28 

FIELD: navigation.

SUBSTANCE: inventions group relates to the field of navigation of upper stages (US) used to launch a spacecraft (SC) into a working orbit. According to the method, the navigation equipment of the consumer of the services of the GLONASS system is used on the US in the spacecraft launching orbits. At the same time, the GLONASS system includes a ground local addition, consisting of a grouping of ground-controlled navigation stations with known coordinates, which form the GLONASS navigation signals. As a result, a navigation field of the required structure is created in the spacecraft injection orbits, the values ​​of navigation vectors obtained on the measured flight segments are processed in the US control center and the parameters of the spacecraft injection orbit are determined.

EFFECT: ensuring the determination of spacecraft injection orbits in the areas of the spacecraft flight above the continuous navigation field formed by the GLONASS system, eliminating the need for trajectory measurements by ground-based systems, ensuring the flexibility of flight control of the spacecraft systems and expanding the spacecraft navigation support area to highly elliptical and geostationary orbits.
