Abstract:Ancillary Terrestrial Component(ATC)technology,which is a powerful candidate of future mobile satellite systems(MSS),is introduced.ATC is deVeloped by Mobile Satellite Ven— tures(MSV)Corporation and represents a group of new technologies involved in MSS. The group of technoIogies give the MSS ability to serve subscribes in dense urban and indoor environ— ments,and bring the ubiquitous coverage of MSS into reality. We study three aspects of ATC: development history,system principle and key technologies.
Key words:MSS;ATC;new development
