Coverage is for customers both in China and in the surrounding countries and regions.  Coverage extends west to Pakistan, north to part of Russia, east to Japan, south to Indonesia.   Part of India is also included.

The satellite technical characteristics (high downlink power and an adjustable range of low to high uplink sensitivities) make it suitable for both broadcast services and also two-way satellite internet connection and access VSAT services.

VSAT service technologies include Linkstar (DVB outbound/DVB-RCS standard TDMA inbound), DVB/Terrestrial return, DVB/SCPC return and SCPC/SCPC.

This is useful if you want to do link budget calculations based on EIRP, uplink G/T and uplink power flux density to saturate.
