The invention provides a method for realizing rapid
recovery of a GEO
satellite after maneuvering through inter-
satellite measurement. Inter-
satellite bidirectional
ranging observation data between the GEO satellite and a configurable chain Beidou satellite can be obtained by utilizing an inter-satellite link load; a non-maneuverable Beidou
satellite orbit serves as a reference, an
orbit determination observation equation is established by utilizing the inter-satellite
ranging observation amount between the non-maneuverable Beidou
satellite orbit and the GEO satellite, and a satellite state time updating equation can be built by utilizing an
orbit dynamics model of the GEO satellite after maneuvering; the observation equation and the satellite state time updating equation are used, the sixnonsingular
orbital elements serve as to-be-estimated parameters, a precise
orbit of the GEO satellite after maneuvering is obtained, and by using the improved orbit, satellite position information of the GEO satellite after maneuvering is obtained through an upper injection
differential correction mode or an orbit forecast and navigation
ephemeris parameter fitting mode. The method effectively shortens the time of Beidou GEO
satellite navigation positioning service interruption caused by orbital maneuvering, and improves the continuity and availability of services of a
satellite navigation system.
