Over on his blog “RTL-SDR DX” dewdudehas been exploring the reception and decoding of Differential GPS (DGPS) signals. DGPS signals are transmitted by government authorities in the long wave band at around 300 kHz. These beacons are used to dramatically improve the accuracy of GPS (Global ...
The following tutorial shows how to receive and decode GPS signals and get a coordinate on a map of your location, using only an RTL-SDR dongle (with bias tee) and GPS antenna. This tutorial is based heavily on Philip Hahn's blog post atsdrgps.blogspot.com/2015/12/first-proof-of-concep...

RTL-SDR Tutorial: Decoding Digital Voice (P25, DMR, NXDN, D-STAR) with DSD Decoding Inmarsat STD-C with Command Line Decoder STDCDEC and SigDigger A Tutorial on using SDRAngel for DMR, D-Star and Fusion Reception with an RTL-SDR
Inmarsat transmits in the L-band at around 1.5 GHz. With an RTL-SDR dongle, a cheap $10 modified GPS antenna or 1-2 LNA's and a patch, dish or helix antenna you can listen to these Inmarsat signals, and in particular decode one channel known as STD-C NCS. This channel is mainly...

Super cheap software defined radios such as the RTL-SDR can be used to decode these digital voice communication signals instead of expensive radio scanners. While this tutorial is aimed at the RTL-SDR, other software radios such as the Funcube dongle, Airspy, HackRF and BladeRF will also work...
signals, with the Outernet signal at the center of the frequency you tuned to (note that if you are using an RTL-SDR without a TCXO, then the signal may be significantly offset). The image below shows what the Outernet signal and surrounding spectrum might look like on the Asia/Pacific ...
Following on from our last post wheredewdude showed how to decode DGPS signals,Frank K2NCChas uploaded a video on YouTube showing DGPS decoding in action. In his video Frank uses an Airspy plus ham-it-up upconverter, a Sirio discone antenna and for software he uses SDR# with audio piped...
