PURPOSE: A moving satellite transmission and reception apparatus and a communication route are provided to control a communication route for receiving a satellite signal received from different communication route without a disconnection phenomenon of a data. CONSTITUTION: A first antenna device(111) receives a signal through a first communications route. A second antenna device(112) receives the signal through a second communications route. A data processor(101) compares a cyclic redundancy check value about a packet stream of the signal received respectively the second antenna device and the first antenna device to the per packet. The data processor changes one communication route among the first communication route and the second communication route when the packet in which the CRC value is same is detected. |
