Abstract: A transmission control method in a satellite communication system and a related apparatus are provided. A terminal may determine, through satellite selection, a target satellite with a strongest signal from at least one satellite in geosynchronous orbit. The terminal may determine a satellite transmission link direction based on location information of the terminal and location information of the target satellite and may further determine a radiation direction of a satellite antenna in the terminal based on geomagnetic data and attitude data of the terminal. The terminal may enable, by using the satellite transmission link direction and the radiation direction of the satellite antenna, the radiation direction of the satellite antenna in the terminal to be aligned with the target satellite. After aligning with the target satellite, the terminal may send a first data packet to the target satellite along the radiation direction of the satellite antenna.
