The invention discloses a method for establishing communication links between master-and-slave satellites, wherein the master-and-slave satellites include one master
satellite and at least one slave
satellite. The method concretely includes the steps that a channel between the master
satellite and each slave satellite is divided into a
control channel and a
communication channel; the master satellite and each slave satellite respectively establish a
system structure of itself; the links are established between the master satellite and the slave satellites, and the communication process starts; the master satellite sends control frames corresponding to all the satellites in a control time slot, each slave satellite captures the synchronous head of the control frames, a local
clock of each slave satellite is calibrated by referring to a local
clock of the master satellite, and time
slot synchronization is completed; after the
time synchronization, each slave satellite sends a communication frame in a communication time slot, link establishment is completed after the master satellite captures the communication frames sent by the slave satellites, a network is adjusted to the
communication channel, and data communication starts. According to the technical scheme, the method for establishing the communication links has the advantages of being capable of
centralized management, easy to maintain, high in safety, short in
delay time and low in transmission
bit error rate.
