4 About the speaker Linux and free software geek since 1999 M.Sc. in C.S. + some E.E. General orientation towards low level Embedded, Kernel, Drivers and such Hardware (Digital stuff, FPGA or RF) Interest in various telecom and SDR projects for several years Osmocom projects (OpenBSC, Osmocom-BB,...) Gnuradio stuff (fosphor, gr-iqbal, #528,...) In my spare time
5 What is GMR? GEO-Mobile Radio Interface (GEO stands for Geostationary Earth Orbit) ETSI standard for satellite phones Heavily based on GSM Multiple standards : GMR-1 (ETSI TS ) GMR-1 (the one described in this talk) GmPRS GMR-1 3G GMR-2 (ETSI TS )
6 Deployment GMR-1 Thuraya Thuraya 2 (44E) and Thuraya 3 (98.5E) Main focus of our attention so far MexSat New! Visible from the US Potential others : EchoStar Mobile, SkyTerra, TerreStar, ICO (Inmarsat R-BGAN) GMR-2 Inmarsat IsatPhone ACes
7 Comparison to GSM Features New names BTS GTS, BSC GSC, BSS GSS,... MS MES(-MS) New Specialized features Terminal-to-Terminal calls High Penetration Alerting (HPA) Tight links to GPS Almanac and Ephemeris sent by the satellite Position reported in RACH (Channel Request) New speech codec: AMBE New cipher
8 Comparison to GSM Protocol Stack Layer 0/1: Completely different Different bursts and TDMA multiplex / multi-frame Different modulation More channels types Layer 2: LAPSat vs LAPDm Both simplified version of LAPD Shorter header k=16 window size for outstanding unacknowledged segments Layer 3: RR different MM/CM common Same core network Packet Data: RLC/MAC different LLC and above common/shared
9 GMR-1
10 Physical layer Frequencies Spot beam coverage L-band Downlink: 1525 to 1560 MHz Uplink: to MHz Divided in 1087 ARFCN (channel pairs) of khz LHCP (Thuraya / MexSat) S-band Downlink: 2170 to 2200 MHz Uplink: 1980 to 2020 MHz 960 / 1280 carriers of khz used independently in DL/UL Feeder Links C-band (DL: to GHz / UL: to GHz) Ku-band (12 to 18 GHz) No specifications
11 Physical layer TDMA Fully synchronous Base symbol rate: 23.4k Bursts occupy several consecutive timeslots (2, 3, 6, 9)
12 Physical layer FCCH: X marks the spot (beam) Dual Chirp waveform over 3 timeslots Synchronization steps 1 Rough position by correlating with reference dual chirp 2 FFT peak of window multiplied by reference up-chirp f 1 3 FFT peak of window multiplied by reference down-chirp f 2 4 Derive time alignement error from f 1 f 2 5 Derive frequency error from f 1 + f 2 Two variants: FCCH: GMR-1 FCCH3: GMR1 3G
13 Physical layer Normal Bursts π/4-cqpsk BCCH, DC2, DC6, NT3, NT6, NT9, RACH π/4-cbpsk DC12 (GMR-1 3G) π/4-cbpsk FACCH3 and SDCCH
14 Physical layer Other Bursts Other modulations used 6-PSK for BACH (HPA) π/4-dbpsk for DKAB GmPRS and GMR-1 3G packet channels (PNB): New modulations: π/2-cbpsk, 16-APSK, 32-APSK New symbol rates: 1x, 2x, 4x, 5x 6-PSK π/2-cbpsk 16-APSK 32-APSK
15 Physical layer What it looks like
16 GMR-1 Reception
17 Reception Antenna Lots of options Requirements: Centered around 1.54 GHz Preferably directional (good gain) LHCP for Thuraya & MexSat Tested so far: Offset Dish Helical Antenna Biquad Patch
18 Reception Filter / LNA Both optional But can help a lot Low Noise Amplifier: Helps with fainter beams LNA-23-BP from dg0ve, modified GPS LNA, LNA4ALL,... Filter: Prevents out-of-band signals from saturating reception chain Custom made L-band cavity filter SAW filter from phone
19 Reception Capture hardware Off-the-air capture tool using gr-osmosdr Supports many radio hardware USRP, BladeRF, HackRF, rtl-sdr,... Requirements: Higher bandwidth is better Narrow channels (32 khz) but need to hop around for traffic channels Tuning to the appropriate frequency range Can be an issue for some R820T tuner based radios GNURadio support Although you could use FIFO with file source too or do your own channelization
20 Osmocom GMR Architecture FIFO SDR Channelization FIFO... Packet Demodulation Decoding gsmtap Wireshark FIFO gmr1_rx_lband.py gmr1_rx_live
21 Osmocom GMR Acquisition / Channelization utils/gmr1 rx lband.py Based on GNURadio Simultaneous synchronized captures of several ARFCN Channelizing and resampling Topology selected based on # of ARFCNs Freq-xlating FIR filters PFB File output Use mkfifo to feed live
22 Osmocom GMR Packet demodulation & decoding Use sylvain/live or sylvain/gmr-1-3g branches Will be merged in master at some point But I still do git push -f to it ATM Contains a whole library of primitives Burst DSP: libosmo-dsp GMR-1 sync & modem: src/sdr/* GMR-1 channel coding: src/l1/* GMR-1 codec: src/codec/* And demo apps: gmr1 rx / gmr1 rx live gmr1 ambe decode
23 Osmocom GMR Packet parsing wireshark FTW! GSMTap extended with GMR-1 support Current state: LAPSat dissection: complete BCCH dissection: partial (CSN-1 is annoying) CCCH dissection: All messages seen so far RR dissection: All messages seen so far CM/MM forwarded to GSM dissector Some unknown / undocumented messages
24 A word about C-band...
