An S-band Mobile Satellite Service (MSS) was added to INSAT
system with the launch of INSAT-3C in 2002 and GSAT-2 in 2003. The following
two classes of services were identified for MSS:
-
A small portable satellite terminal that works with INSAT for
voice/data communication has been developed with the participation of Indian
industries. The terminal is useful for voice communication especially during
disasters when other means of communication break down. It can be used from any
location in India for emergency communication. Transmit and receive frequencies
of the terminal are in S-Band.
-
The portable terminal is connected to the EPABX at central
hub station through satellite channel and hence could be considered as an
extension of EPABX and call could be made between any satellite terminals and
local phones on EPABX. Central hub station is located at SAC, Ahmedabad.
