Garuda 1
Garuda 1 was an Indonesian communications satellite which is operated by ACeS. It was constructed by Lockheed Martin and is based on the A2100AXX satellite bus. It has two very large antennas, each measuring 12 meter in diameter. Launch occurred on 12 February 2000, at 09:10:54 GMT. The launch was contracted by ILS, and used a Proton-K/ DM3 carrier rocket flying from Site 81/23 at the Baikonur Cosmodrome. History At the time of its launch, it was the heaviest commercial payload to be launched by a Proton. During its launch, the Block DM3 upper stage made three burns instead of the usual two. This was the first time that the Block DM had used a three-burn ascent profile. Following its launch and on-orbit testing, it was placed in geostationary orbit at 123° East, from where it provides communications services to Asia. It is equipped with 88 transponders, allowing it to cover the entire continent with 140 spot beams. The satellite is controlled by ACeS Satellite Control Facility ...

Satellite Phone
A satellite telephone, satellite phone or satphone is a type of mobile phone that connects to other phones or the telephone network by radio through orbiting satellites instead of terrestrial cell sites, as cellphones do. The advantage of a satphone is that its use is not limited to areas covered by cell towers; it can be used in most or all geographic locations on the Earth's surface. The mobile equipment, also known as a terminal, varies widely. Early satellite phone handsets had a size and weight comparable to that of a late-1980s or early-1990s mobile phone, but usually with a large retractable antenna. More recent satellite phones are similar in size to a regular mobile phone while some prototype satellite phones have no distinguishable difference from an ordinary smartphone. Satphones are popular on expeditions into remote areas where terrestrial cellular service is unavailable. A fixed installation, such as one used aboard a ship, may include large, rugged, rack-mo ...

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 SkyTerra (SKYT), formerly Mobile Satellite Ventures (MSV or MSVLP), was a Reston, Virginia company that developed telecommunications systems that integrate satellite and terrestrial radio communication technologies into one system.

International Networks (country Code)
International Networks is the name given by the International Telecommunication Union (ITU) to country calling codes +882 and +883, and serves as a catch-all for telephone services not dedicated to a single country. Satellite telephone carriers, especially those with worldwide service, are allocated within the Global Mobile Satellite System (GMSS), country code +881, with the exception of non-terrestrial Inmarsat, country code 870. As in the other such shared country codes, carriers are allocated number space within this code space plus their identification code (two-digit number in 882 code space, three or four digit number in 883 code space). The phone number for a subscriber of such a service starts with +882/+883 followed by the carrier code. The cost to call such a number can be high; for example in the British Telecom price list rates for various 882 and 883 numbers ranged from £0.60 to £4.50 per minute. Carrier codes As of November 27, 2017 the assignments of +882/+883 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Communications Satellites
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications satel ...
