This is a photo of my old, long gone, Inmarsat system built back in 1991 just before Desert Storm #1 - antenna was pointing at 64E Inmarsat IOR used by the CNN crew for live reporting from Baghdad. Tin can feed and FET LNA with 2 MMIC's after for line driver, AOR3000 RX. https://t.co/PIawDxz0Tl

Aero Decoding and Full Support for HackRF One
After some work it is now possible to fully support HackRF One with my Inmarsat Aero decoder. In the past, the Inmarsat Aero decoder used two SDRs (each covering 2MHz) to cover up to 4MHz of L-Band spectrum as well … Continue reading
Adding External Reference to HackRF One SDR
The HackRF One SDR is a great value but it’s frequency stability leaves something to be desired. Using the Si5338 clock generator from Silicon Laboratories is an easy way to address the problem (if it’s really a problem for your … Continue reading
HackRF One and Decoders
I’m always looking for opportunities to reduce the costs associated with high quality decoding tasks. The HackRF One is intriguing because it’s not very expensive, has a wide band receiver (10MHz – 6GHz) and an SDR that is capable of … Continue reading
Aero Coverage of POR and CONUS
The diagram below illustrates the current Aero coverage that is possible here at USA-Satcom. As you can see there is quite a bit of IQ bandwidth to deal with and consequently at least two i7 hex core machines are needed … Continue reading
Operation Deep Freeze 2014
It’s that time of year again! Regular science crew transportation missions to and from Antarctica using US Air Force aircraft. Communications occur via Military Satcom in the Pacific Ocean Region. Below are a few recent satcom intercepts as well as … Continue reading
