Final Report Figure 24: Thuraya satellite coverage In addition to satellite coverage, Thuraya has an agreement with more than 300 GSM partners worldwide in order to offer GSM roaming services over land-based mobile GSM networks. It is an interesting feature since dual mode terminals (satellite and GSM) are capable to change the access network when the favourite/current one is not available. Figure 25 shows current GSM coverage provided by GSM partners worldwide. Figure 25: Thuraya GSM coverage provided by partners worldwide In this sense, this dual coverage is complemented with SIM compatibilities between systems (satellite and terrestrial GSM). It means that Thuraya SIM cards work in regular GSM mobile phones, and viceversa (as long as the SIM provider has a roaming agreement with Thuraya).

Final Report Thuraya‘s satellites have been designed to achieve network capacity of about 13,750 telephone channels. Thuraya‘s handheld terminals are comparable to GSM handsets in terms of size and appearance, as well as in voice quality (although it introduces a noticeable delay due to the distance between terminal and GEO satellite). Regarding Thuraya handhelds, it is interesting to highlight that exist a kind of sleeve that adapts to several commercial GSM phones with the aim of converting them (regular GSM phones) to SATCOM terminals (see Figure 26). These terminals are called ―Thuraya SatSleeve‖, and can reduce costs. Figure 26: Thuraya SatSleeve terminals (enable regular GSM terminals as a Satcom terminals) Thuraya access scheme is based on TDMA (Time Division Multiple Access), and the service is operated in L-band (it refers to the user link, which makes possible the use of handhelds). Frequencies at user-link are the following: - Earth-to-space: 1626.5-1660.5 MHz - Space-to-Earth: 1525.0-1559.0 MHz In the feeder-link, Thuraya uses C-band for the uplink and S-band for the downlink: - Earth-to-space: 6425.0-6725.0 MHz - Space-to-Earth: 3400.0-3625.0 MHz Regarding services, Thuraya provides voice and data communications: - Voice communications with handhelds or fixed terminals - Data with satellite handhelds: 60kbps downlink / 15 kbps uplink - Data with fixed SATCOM terminals: 144 kbps downlink - SMS - Some other services related with voice: missed calls, voicemail, call waiting.... - Etc 6.2.7 Inmarsat 4 (BGAN) and 6 (ICE) (GEO L-band) Inmarsat, like Iridium, is a proprietary commercial satellite system that offers global coverage. It has been chosen to be analysed as a current narrowband satellite system for railway safety-critical applications due that: Global coverage (achieved with 3 GEO satellites, see Figure 27).
