Description of the System
Introduction
The W61SAT Option allows the monitoring of the L-band downlink in the 1550 MHz range - the forward 
path - of the INMARSAT System. This link contains the traffic from the Land Earth Station, LES to the Mo-
bile Earth Stations, MES. 
'EasySatSystem' is an application that manages the satellite decoding modes running on a system of up to 
10 W61PC cards to prevent that more than one W61PC card monitors the same satellite communication 
session, identified by a specific satellite mode (INMARSAT-B, INMARSAT-M, INMARSAT-mini-M and IN-
MARSAT-C), a service (data, fax, ISDN, etc.), and mobile earth station identification number (termed MES 
Id in the following). The monitoring system configuration is specified in a text file using a very simple syn-
tax. For logging purposes, statistical data concerning the monitored sessions can be collected. 
'EasySatSystem' has three kinds of user interfaces: 
the operational status display of the coordinated cards, i.e., the „EasySatSystem‟ graphical user interface 
(GUI) 
the configuration interface, i.e., the text file EasySATSystem.ini, stored in same predefined directory 
 
Hardware
The monitoring system consists of three main components:
An antenna, including a low noise amplifier (LNA)
Down converter
