SATELLITE COMMUNICATION SYSTEM AND METHOD BASED ON DIGITAL VIDEO BROADCASTING-RETURN CHANNEL VIA SATELLITE (DVB-RCS)

摘要

A satellite communication system and method based on a digital video broadcasting-return channel via satellite (DVB-RCS) are provided. The satellite communication system may include a central station, and at least one very small aperture terminal (VSAT) including a first VSAT and a second VSAT. When a logon request is received from the second VSAT, the central station may determine whether the first VSAT is normally operated. When the first VSAT is determined to be abnormally operated, the central station may allow the second VSAT to log onto the central station.
