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 Gbit/s of capacity, which is more than The expert interviewed for the series is Ratnakar Rao V R, who heads the Beyond 5G Team at Samsung R&D Institute India – Bangalore (SRI-B). Rao is soon to complete a decade at SRI-B, and the bulk of his experience has been in the research and development of Communication (from Latin communicare, meaning "to share" or "to be in relation with") is "an apparent answer to the painful divisions between self and other, private and public, and inner thought and outer world." As this definition indicates, communication is difficult to define in a consistent manner, because it is commonly used to refer to a wide range of different behaviors (broadly: "the

High-throughput satellite HTS is a communications satellite that provides more throughput than a classic FSS satellite at least twice, though satellite communication research paper by a factor of 20 or more [1] for the same amount of allocated orbital satellite communication research paperthus significantly reducing cost-per-bit.
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 [1] spot beams usually in the order of hundreds of kilometers[1] as in cellular networks, which both are defining technical features of high-throughput satellites. By contrast traditional satellite technology utilizes a broad single beam usually in the order of thousands of kilometers satellite communication research paper to cover wide regions or even entire continents.
Initially, HTS systems used satellites in the same geosynchronous orbit at an altitude of 35, satellite communication research paper, km as satellite TV craft with satellites such as KA-SATsatellite communication research paper, Yahsat 1A and Astra 2E sharing TV and HTS functionality but the propagation delay for a round-trip internet protocol transmission via a geosynchronous satellite can exceed ms which is detrimental to many digital connectivity applications, such as automated stock trades, hardcore gaming and Skype video chats.
Despite the higher costs associated with spot beam technology, the overall cost per circuit is considerably lower as compared to shaped beam technology. HTS are primarily deployed to provide broadband Satellite communication research paper access service point-to-point to regions unserved or underserved by terrestrial technologies where they can deliver services comparable to terrestrial services in terms of pricing and bandwidth. While many current HTS platforms were designed to serve the consumer broadband market, satellite communication research paper, some are also offering services to government and enterprise markets, as well as to terrestrial cellular network operators who face growing demand for broadband backhaul to rural cell sites.
For cellular backhaul, the reduced cost per bit of many HTS platforms creates a significantly more favorable economic model for wireless operators to use satellite for cellular voice and data backhaul. Some HTS platforms are designed primarily for the enterprise, telecom or maritime sectors.
HTS can furthermore support point-to-multipoint applications and even broadcast services such as DTH distribution to relatively small geographic areas served by a single spot beam. A fundamental difference between HTS satellites is the fact that certain HTS are linked to ground infrastructure through a feeder link using a regional spot beam dictating the location of possible teleports while other HTS satellites allow the use of any spot beam for the location of the teleports.
In the latter case, the teleports can be set up in a wider area as their spotbeams' footprints cover entire continents and regions like it is the case for traditional satellites. Industry analysts at Northern Sky Research believe that high-throughput satellites will supply at least 1. From Wikipedia, the satellite communication research paper encyclopedia.

In the 90s, constellations such as Iridium and Globalstar started the trend of offering communication services from space using non-geostationary satellite orbits (NGSO). However, they failed to accomplish their objective due to the lack of economic viability of the projects [1]. Now
