| W61SAT Option |
 | The W61PC is the first choice to build a cost efficient satellite monitoring system for INMARSAT.
The W61SAT modes are a software option for the professional versions of the WAVECOM® decoders.
The W61PC has a fully tunable 70 MHz IF input for satellite monitoring (no external receivers are required). |

Satellite and Receiver Setup for Decoding INMARSAT B/M/mM
|
| INMARSAT A |
| With the SAT-A mode, the forward channel (TDM telex traffic) can be monitored. |
| INMARSAT B |
 | With the SAT-B mode, data, fax and digital voice traffic can be monitored.
In our next release, demodulation and decoding of digital voice will also be supported.
L-Band only, forward channel monitoring (does not require a large C-Band antenna) is supported. |
| INMARSAT C (TDM, TDMA) |
| | With the SAT-C-TDM and SAT-C-TDMA mode, data traffic going in both directions can be monitored. |
| INMARSAT M |
M spectrum
| With the SAT-M mode, data and fax traffic can be monitored.
L-Band only, forward channel monitoring (does not require a large C-Band antenna) is supported. |
| INMARSAT mM |
mM spectrum
| With the SAT-mM mode, data and fax traffic can be monitored.
L-Band only, forward channel monitoring (does not require a large C-Band antenna) is supported. |
| Single Channel Monitoring System |
Fax session
| The W51SAT monitors the control channel, and upon initiation of a new session with a Mobile Terminal, automatically switches to the assigned Traffic Channel for monitoring. To limit the volume of monitored traffic, a watch list may be created containing target MES IDs. Monitored fax, Tel and data sessions are stored in files. A fax viewer is included in the software. |
| Multi Channel Monitoring System |
| | To monitor multiple INMARSAT B, M or mM channels with more then one card, an external, customer specific control software using remote control is required. Many customer write own their own software optimized for the special requirements. On request WAVECOM can provide also such additional control software. |
| Near Field Monitoring System |
| | To monitor multiple INMARSAT B, M or mM terminals that are in you very close neighborhood, a specialized setup of the Single Channel Monitoring System is required. |
