Fleet Tracking on Inmarsat 4F3
Most of the popular Inmarsat activity is associated with ships and planes in AOR-E, AOR-W, POR and IOR. There is an Inmarsat satellite called 4F3 parked at 98W that gives CONUS coverage. This satellite is inclined and so does move … Continue reading
New Inmarsat Aero-H and H+ Decoder in Development
Another new decoder project is in the works. This is another Multi-Channel decoder for Aero but instead of just ACARS and CPDLC it does AMBE and LPC voice decode. The screenshot below shows call logging status output from the prototype … Continue reading
Inmarsat Aero-P ACARS Multi-Channel Decoder
Inmarsat Aero-P includes an ACARS service for airlines to use while transiting the various ocean regions. This is much more reliable than HF ACARS. Inmarsat hosts 3-4 Aero-P control channels on L-Band for each ocean region. Each control channel is … Continue reading
Multi-Channel Inmarsat-C Decoder
Below is graphical overview of Marine-C, an Ethernet based Multi-Channel Inmarsat-C decoder. The decoder is able to simultaneous decode up to 12 channels and therefore can cover an entire ocean region with this single application. The decoder monitors all LES … Continue reading
New Hardware for some new Software
I have been working on some new decoding software that directly interfaces to RF Space SDR-IP or NetSDR. These SDR’s provide wide-band IQ data over Ethernet and are ideal for plug and play operation. All the new decoders are multi-channel … Continue reading
Inmarsat STD-C
Inmarsat STD-C is a data or message-based system used mostly by maritime operators. An Inmarsat C terminal transmits and received on L-Band to various geosynchronous satellites that service each major ocean region (POR, IOR, AOR-E, AOR-W). The information rate is … Continue reading
Inmarsat FAX
Inmarsat STD-B service is still active, even after all these years. On STD-B you will find voice, data and fax services Here are a couple of examples of recently received faxes via Inmarsat 3F3 Pacific Ocean Region (POR) at 178°. … Continue reading
