Globalstar Facts in Brief
Country: Operations worldwide, US headquarters located in Louisiana Operations: Globalstar
Status: The first of four launches of six new second-generation satellites was successfully completed on October, 2010. Two additional launches were successfully conducted in July and December of 2011, respectively. The fourth launch is expected to take place in 2012. Coverage: 120 countries worldwide; 80% of the Earth’s surface, everywhere outside the extreme polar regions and some mid-ocean regions. Orbit: Low Earth Orbiting satellite constellation Key Service Areas: Phone and accessories, voice services, data and tracking Web link: http://ca.globalstar.com/en/index.php?cid=100 Globalstar is one of the world’s largest providers of mobile satellite voice and data services and offers services to commercial and recreational users in more than 120 countries. Company products include mobile and fixed satellite telephones, simplex and duplex satellite data modems and satellite data services. In October 2010, Globalstar began launching its second-generation satellite constellation designed to restore its industry leading commercial voice and duplex data services. Once fully deployed the advanced second-generation constellation and next- generation ground network will provide Globalstar customers with enhanced services featuring increased data speeds of up to 256 kbps in a flexible Internet protocol multimedia subsystem (IMS) configuration. Globalstar offers communications services that provide several key capabilities including clarity of voice ; QUALCOMM’s CDMA (Code Division Multiple Access) technology makes Globalstar calls secure and clear, often with better voice quality than cellular networks, and greater system capacity. Minimal perceptible voice delay-Use of Low Earth Orbiting (LEO) satellites, moving at an altitude of 1,414 kilometres, means almost no perceptible voice delay, as compared with the noticeable time delay and echo effect of calls utilizing geosynchronous satellites. Next generation products and services supported are expected to include: Push-to-talk and multicasting; Advanced messaging capabilities such as multimedia messaging or MMS; Mobile video; Geo-location services; Multi-band and multi-mode handsets; Data devices with GPS integration. The Globalstar portfolio of products assists customers to keep in contact from remote locations or worksites, namely those located in the high north, with the use of the Handheld Phone while traveling in remote areas, or one of their Fixed Phones for remote offices or dwellings. Globalstar products and accessories can connect in places where cellular and landline are unavailable. Globalstar also offers specialized data modems to send and/or receive information from remote jobsites or track and monitor company assets. Country: Global presence with offices located in 40 countries world-wide, headquarters in London, England Operations: Inmarsat Inc. Status: Inmarsat-4 series currently in operation; these three satellites make up the global I-4 constellation and are part of an 11-strong fleet of spacecraft owned and operated by Inmarsat; planned launch of three new Ka- band mobile satellites starting in 2013 to introduce global broadband mobile satellite services by end of 2014 (Inmarsat-5 Global Xpress TM ) Mission Duration: Expected operation life of Inmarsat- 4 series into the 2020s. Coverage: Broadband Global Area Network (BGAN) services worldwide Orbit: Geosynchronous orbit at 35,786 km above Earth Key Service Areas: voice and high-speed data services to almost anywhere on the planet (land, sea and air) including fixed and mobile satellite phones, email, internet and intranet services, telex, distress calls, text and data messaging Web link: http://www.inmarsat.com/About/Our_satellites/default.aspx?language=EN&textonly=False Inmarsat has provided mobile satellite services for more than 32 years with key service areas including global voice, data and IP communications solutions that deliver communications services where terrestrial networks don’t go or are ineffective. Inmarsat owns and operates a fleet of 11 satellites in geostationary orbit that provide these services on land, at sea or in the air. Inmarsat also offers expertise in a range of cross-platform mobile and fixed satellite, microwave and wireless technologies. Inmarsat provides the following system capabilities: (i) standard IP, which allows for email internet and intranet access at speeds up to 492 kbps over a shared channel; (ii) streaming IP- providing guaranteed data on demand at rates in excess of 384 kbps. (iii) Phone and data applications available simultaneously. Voicemail and other stand 3G mobile supplementary services are also available; (iv) Send and receive text message to or from any mobile phone.
