Abstract

A communication satellite comprises at least one antenna configured to communicate with at least one ground terminal over a first communication link in a first frequency band and a second communication link in a second frequency band. The first communication link and the second communication link are for communicating the same information. A satellite communication system comprises a first satellite having a first antenna configured to communicate with a ground terminal over a first communication link in a first frequency band and a second communication link in a second frequency band. The satellite communication system further comprises a second satellite having a second antenna configured to communicate with the ground terminal over a third communication link in the first frequency band and a fourth communication link in the second frequency band. The first communication link and the second communication link are for communicating the same information. The third communication link and the fourth communication link are for communicating the same information
