Because the gesture of the satellite terminal is related to the intensity of the signal received by the satellite terminal, when the intensity of the received signal of the satellite terminal is smaller than a preset signal intensity critical value, the gesture of the satellite terminal is adjusted, so that the direction of the satellite terminal antenna is aligned to the direction of the satellite, and the intensity of the signal received by the satellite terminal is increased, thereby improving the call quality of the satellite terminal. Meanwhile, compared with the mode of adopting a terminal screen to display and adjust the information of the gesture of the satellite terminal, the voice prompt mode is adopted, so that a user can not hear opposite-end voice information in time and the condition of information omission caused by frequently taking down the terminal to observe the screen information in the process of talking, and the talking experience of the user can be improved by adopting the voice prompt mode.
