> Abstract:
>    This document presents the detailed analysis about the problems and
>    requirements of satellite constellation used for Internet.  It starts
>    from the satellite orbit basics, coverage calculation, then it
>    estimates the time constraints for the communications between
>    satellite and ground-station, also between satellites.  How to use
>    satellite constellation for Internet is discussed in details
>    including the satellite relay and satellite networking.  The problems
>    and requirements of using traditional network technology for
>    satellite network integrating with Internet are finally outlined.
