Posted on Sunday, May 27th, 2012 in open source, RF, talks by the machinegeek


In this video from the 28C3 Conference in Berlin, Sylvain Munaut describes the latest member of the Osmocom-family projects, osmo-gmr. This project focuses on the GMR-1 (GEO Mobile Radio) air interface used in some satellite Phones. Sylvain discusses the GMR protocol, the Thuraya network that uses this protocol in the Eurasian/African and Australian continents and finally details how you can capture samples and process them for analysis using osmo-gmr.

The PDF of the slides from this talk can be downloaded here. Read the project details and download code from the osmocom-gmr website.
