Introducing Osmo-GMR

Building a sniffer for the GMR satphones

The latest member of the Osmocom-family projects, osmo-gmr focuses on the GMR-1 (GEO Mobile Radio) air interface used in some satellite Phones. This talk will shortly present 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.
