this satellite was positioned above korea for testing purposes . it was launched on 21 october 2000 by sea launch on a zenit 3sl rocket . 5 at launch it weighed 5250 kg . 6 the satellite was used for testing and backup until may 2007 when it was moved to junk orbit and declared at its end of life . 7 thuraya 2 thuraya 2 was launched by sea launch on 10 june 2003 . 8 it is located in geosynchronous orbit at 44 e longitude inclined at 6.3 degrees . 9 the satellite can handle 13 750 simultaneous voice calls . this satellite currently serves most of europe the middle east africa and parts of asia . the craft had a weight of 3200 kg and an expected life of 12 years . the two solar panel wings each containing five panels generate 11 kw electric power at end of life . the craft has two antenna systems a round c band antenna 1.27 meters in diameter and a 12 16 meter astromesh reflector 128 element l band antenna supplied by astro aerospace in carpenteria ca . these antennas support up to 351 separate spot beams each configurable to concentrate power where usage needs it . 10 thuraya 3 the third satellite was planned for launch by sea launch in q1 2007 and the start of far east and australia service was planned for 15 october 2007 . the failure in january 2007 of the nss 8 rocket led to a substantial delay in the launch of thuraya 3 which was rescheduled for 14 november 2007 but the launch was postponed several times due to sea conditions . 11 the launch vessels set out from port again on 2 january 2008 and launch occurred successfully at 11 49 gmt on 15 january 2008 . 12 13 the thuraya 3 satellite is technically the same as thuraya 2 but located in geosynchronous orbit at 98.5 e longitude inclined at 6.2 degrees . subscriber hardware edit handsets edit ascom 21 first generation handset monochrome display 9600 bit s dial up data gsm900 compatible hughes 7100 first generation handset monochrome display 9600 bit s dial up data gsm900 compatible hughes 7101 functionally identical to hughes 7100 but with added wireless application protocol support thuraya so 2510 second generation handset supports gmprs 60 15 kbit s runs vxworks thuraya sg 2520 second generation handset supports gmprs 60 15 kbit s runs windows mobile gsm900 1800 compatible thuraya xt third generation handset supports gmprs thuraya xt dual third generation handset supports gmprs gsm900 1800 1900 thuraya xt pro third generation handset supports gmprs thuraya xt lite third generation handset no packet data support hughes 7101 thuraya so 2510 thuraya sim thuraya phone in use sleeves edit satsleeve for android satsleeve for iphone satsleeve plus satsleeve hotspot see also edit broadband global area network geo mobile radio interface globalstar inmarsat iridium o3b skyterra skywave mobile communications references edit arabic stars stellarium wiki . pr sch roland ;
