Shoghi
Designs and Integrates various Systems and Sub systems to deliver world Class
Integrated Communication Interception, Logging and Analysis systems to its various
Defence and Government Customers.
ACeS
started its commercial operations for GSM like L-band mobile satellite commercial
services in Southeast Asia since 2001 after launch of the Lockheed Martin A2100XX
satellite in February 2000.
According
to ACeS, there are 100,000 terminal users today. Mostly for rural and village
based use on voice services.
ACeS is
based on GMR-2 specifications which is an ETSI standard alike Thuraya (GMR-1)
and both are defined as ’satellite GSM’. ACeS offer speech/voice and 2400 bps
data services.
ACeS Coverage
The
ACeS coverage area is over 11 million square miles extending from Pakistan and
India in the west, to the Philippines and Papua New Guinea in the east, and from
Japan and China in the north down to Indonesia in the south.
These countries have a combined population of approximately three billion people, the
majority of whom are currently underserved by telecommunication services.
Passive
ACeS Interception and Protocol Decoding Solution
The
solution is based on an Integrated Design from Shoghi Communications Ltd.
The
solution can be extended to a fixed/strategic system and also include other satellite
services like Inmarsat and Thuraya. The software is prepared for this – and the
demodulators are software-defined which enables easy inclusion of other waveforms.
The
solution offered is based on the ITU/ETSI GMR-2 specifications for ACeS and will
be fully compliant to these specifications.
