HSD Aeronautical Transceivers 

2 

HSD aeronautical transceivers provide a digital connection, 
between aircraft and ground communication networks, 
using the Inmarsat Satellite Communications system and 
the international public telephone network. 

HSD products support EIA/TIA-232, ISDN, and Ethernet 
connectivity between an aircraft and selected Land Earth 
Stations, using the Inmarsat Satellite Communications 
system and the international Public Switched Telephone 
Network (PSTN). 

The HSD transceivers act as a Mobile Earth Station 
(MES)—sending and receiving voice, fax, video, and data 
over satellite links.  

Services and features 

HSD transceivers’ services and features vary depending on 
the model and installation configuration-mode. The 
following section provides descriptions of all HSD models 
and configuration-modes documented in this User’s Guide. 

HSD transceivers are available in models that are installed 
as stand-alone systems or integrated into existing SATCOM 
systems.
