Private Limited Company
A private limited company is any type of business entity in "private" ownership used in many jurisdictions, in contrast to a publicly listed company, with some differences from country to country. Examples include the '' LLC'' in the United States, ''private company limited by shares'' in the United Kingdom, '' GmbH'' in Germany and Austria, ''société à responsabilité limitée'' in France, and ''sociedad de responsabilidad limitada'' in the Spanish-speaking world. The benefit of having a private limited company is that there is limited liability. However, shares can only be sold to shareholders in the business, which means that it can be difficult to liquidate such a company. Abbreviations Albania In Albania a limited liability company ( sq, Shoqëri me përgjegjësi të kufizuar Sh.p.k) is a commercial company founded by persons of physical or judicial status, who are not liable for the company and personally bear losses only up to the outstanding contribution agreeme ...

Geostationary Orbit
A geostationary orbit, also referred to as a geosynchronous equatorial orbit''Geostationary orbit'' and ''Geosynchronous (equatorial) orbit'' are used somewhat interchangeably in sources. (GEO), is a circular geosynchronous orbit in altitude above Earth's equator ( in radius from Earth's center) and following the direction of Earth's rotation. An object in such an orbit has an orbital period equal to Earth's rotational period, one sidereal day, and so to ground observers it appears motionless, in a fixed position in the sky. The concept of a geostationary orbit was popularised by the science fiction writer Arthur C. Clarke in the 1940s as a way to revolutionise telecommunications, and the first satellite to be placed in this kind of orbit was launched in 1963. Communications satellites are often placed in a geostationary orbit so that Earth-based satellite antennas do not have to rotate to track them but can be pointed permanently at the position in the sky where the sat ...

High-throughput Satellite
High-throughput satellite (HTS) is a communications satellite that provides more throughput than a classic FSS satellite (at least twice, though usually by a factor of 20 or more) for the same amount of allocated orbital spectrum, thus significantly reducing cost-per-bit. ViaSat-1 and EchoStar XVII (also known as Jupiter-1) do provide more than 100 Gbit/s of capacity, which is more than 100 times the capacity offered by a conventional FSS satellite. When it was launched in October 2011 ViaSat-1 had more capacity (140 Gbit/s) than all other commercial communications satellites over North America combined. Overview The significant increase in capacity is achieved by a high level frequency re-use and spot beam technology which enables frequency re-use across multiple narrowly focused spot beams (usually in the order of hundreds of kilometers), as in cellular networks, which both are defining technical features of high-throughput satellites. By contrast traditional satellite technolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HYLAS-1
HYLAS (or HYLAS-1) is a British satellite in geostationary orbit. HYLAS, which is an acronym for ''Highly Adaptable Satellite'', is a communications satellite and was launched by the European Ariane 5 launch vehicle from the Guyana Space Centre at Kourou in French Guiana. It is located at the orbital location of 33.5 degrees west and will provide new and innovative services including High Definition Television (HDTV) and interactive satellite delivered broadband services. The satellite will help address the issue of poor broadband coverage in many parts of Europe which have less developed ground infrastructure. Construction HYLAS was constructed by EADS Astrium for the UK telecommunications company Avanti Communications Plc. Development of the satellite was supported by a £23m investment from the British National Space Centre (BNSC). Launch Avanti purchased for HYLAS a launch to geostationary transfer orbit (GTO) on a Falcon 9 launch vehicle. The purchase, in September 2007, ...

EDRS-C
The European Data Relay System (EDRS) system is a European constellation of GEO satellites that relay information and data between satellites, spacecraft, UAVs, and ground stations. The first components (a payload and dedicated GEO satellite) were launched in 2016 and 2019. Purpose and context The designers intend the system to provide almost full-time communication, even with satellites in low Earth orbit that often have reduced visibility from ground stations. It makes on-demand data available to, for example, rescue workers who want near-real-time satellite data of a crisis region. There are a number of key services that will benefit from this system's infrastructure: * Earth Observation applications in support of time-critical and/or data-intensive services; e.g., change detection, environmental monitoring. * Government and security services that need images from key European space systems such as Global Monitoring for Environment and Security. * Emergency response and crisis ...
