    摘要: The present invention relates to the field systems and methods that allow for two-way telematics applications, where the term telematics refers to the transfer of data to and from a moving vehicle. A telematics interface device (210) comprises: a receiver (214,216) attached to a vehicle to receive radio signals (254) from a satellite (252) that contain telematics information; and a back-channel (204) that sends telematics information (245) outside of said vehicle independently of the satellite (252). This device (210) can then be used in a two-way satellite digital audio radio system comprising: a ground station (108) ; an information source means (209) for providing information connected to the ground station (108); a satellite (252) in communication (250) with said ground station (180); a satellite-air interface (106) for providing communication between the satellite (252) and the telematics interface device (210). The back-channel (204) is in communication with the information source (209) independently of the satellite.
