The invention belongs to the technical field of navigation
satellite precision
orbit determination, and specifically relates to a navigation
satellite orbit rapid
recovery method based on short arc
orbit determination and forecast. The navigation
satellite orbit rapid
recovery method based on short arc
orbit determination and forecast includes the steps: through short arc
orbit determination and short arc forecast, taking the distance from of the satellite at a reference epoch to the geocenter as the radial component, taking the distance from the satellite to the initial
orbit plane as the secondary
normal component, taking the third component defined according to the
right hand rule of the coordinate
system as the tangential component, taking the
time rate of change of the radial component, the secondary
normal component and the tangential component, and performing rapid
recovery of the navigation
satellite orbit through compatible user
ephemeris calculation with an additional component correction value. The navigation
satellite orbit rapid
recovery method based on short arc
orbit determination and forecast can realize seamless docking of the
ephemeris solution method of the userbefore and after orbit control, can improve the accuracy of
satellite orbit determination and forecast, can obtain the satellite precise orbit of the user application demand in a relatively short timeafter orbit control, and can make accurate forecast so as to enable the satellite to resume normal use and guarantee normal operation of the
satellite system, and has important guiding significance for the technical field of navigation
satellite orbit determination.
