Abstract:

The problem of orbital injection state and deviation propagation of spacecraft is studied in this paper. This relationship between the velocity square ratio of orbital injection and the velocity elevation angle and the main orbital parameters when the rocket extinguishes is derived to analyze the orbital injection state of the spacecraft. The deviation propagation matrix of the spacecraft's transfer orbit is established, and the influence of the orbit inject deviation on the transfer orbit is obtained. The deviation propagation analysis method in this paper is compared with the traditional orbital error analysis method to verify the correctness of the proposed method. Finally, the influence of spacecraft's orbital injection state and orbit inject deviation on the transfer orbit is analyzed through simulation example.

Key words: orbital parameters, orbital injection state, orbit inject deviation, deviation propagation matrix
