GEO-Mobile Radio Interface
GEO-Mobile Radio Interface (GEO stands for Geostationary Earth Orbit), better known as GMR, is an ETSI standard for satellite phones. The GMR standard is derived from the 3GPP-family terrestrial digital cellular standards and supports access to GSM/UMTS core networks. It is used by ACeS, ICO, Inmarsat, SkyTerra, TerreStar and Thuraya. There are two widely deployed variants of GMR, both heavily modeled after GSM * GMR-1: The first version of the standard and that has evolved over time into 3 different revisions: ** GMR-1: The basic circuit switched model, more or less corresponding to what GSM Phase 2 is, and using exactly the same core network infrastructure. ** GmPRS: Adding support for packet data. The equivalent of GPRS in the GSM world. Still connected to a 'Gb' style core network. ** GMR-1 3G: Adds support for some new channel types, but the most important changes are in the core network, adding interoperability with UMTS core network components. Contrary to the classic ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ariane 5
Ariane 5 is a European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It is launched from the Centre Spatial Guyanais (CSG) in French Guiana. It has been used to deliver payloads into geostationary transfer orbit (GTO) or low Earth orbit (LEO). The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6, a direct successor system, is in development. The system was designed as an expendable launch system by the ''Centre national d'études spatiales'' (CNES), the French government's space agency, in cooperation with various European partners. Despite not being a direct derivative of its predecessor launch vehicle program, it is classified as part of the Ariane rocket family. ArianeGroup is the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European contractors. Ariane 5 was originally intende ...

Mobile-satellite Service
Mobile-satellite service (MSS, or mobile-satellite radiocommunication service) is – according to Article 1.25 of the International Telecommunication Union's Radio Regulations – "A radiocommunication service * between mobile earth stations and one or more space stations, or between space stations used by this service; or * between mobile earth stations by means of one or more space stations. This service may also include feeder links necessary for its operation." Details Most commercial voice and some data mobile satellite services are provided by systems operating in the L-band by Iridium, Inmarsat, Globalstar and Thuraya. The L-band spectrum allocated for MSS is between 1.5 and 2.5 GHz, with the upper portion often referred to as the S-band. Constellations of low earth orbiting (LEO) satellites are used by Iridium (66 satellites) and Globalstar (48 satellites). Inmarsat and Thuraya currently use 4 (i4) and 2 geostationary satellites respectively, their L-band services are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A Human Right
A Human Right is a non-profit organization dedicated to providing free basic internet and phone access to developing countries, and to citizens of countries whose government has cut off or restricted internet access. It was discontinued in 2016. Buy This Satellite In December 2010 they launched Buy This Satellite, a fundraising effort to purchase the TerreStar-1 communications satellite, after its owner, TerreStar Corporation, filed for bankruptcy. The idea to purchase the satellite developed out of a meeting in Berlin of thirty people under the age of thirty, described by A Human Right's founder, Kosta Grammatis, as a "do tank" (as opposed to a think tank). A Human Right hopes that providing internet access to impoverished regions of the world would help to solve many of their problems, such as shortages of food, potable water, and health care. Grammatis believes that, "People are ingenious. If you give people access to information, they can solve their own problems." Intern ...
