The invention provides a satellite communication method and apparatus wherein the method comprises the following steps: detecting whether a first direct communication path between a first phased array antenna arranged on the first compartment of a train and a satellite is blocked or not; obtaining a detection result; if the detection result is yes, determining whether a second direct communication path between a second phased array antenna arranged on the second compartment of the train and the satellite is blocked or not and a first communication link is created between the first phased array antenna and the second phased array antenna; and through the first communication link and the second direct communication path, transmitting the communication information between the first phased array antenna and the satellite. According to the technical schemes of the invention, it is possible to maintain the bi-direction communication service with the satellite even when the direct communication paths between phased array antennas on the compartments of a train and the satellite are blocked, therefore, meeting the communication requirement of users on the train.
