high throughput satellite (Sat-Internet) (HTS)

High Throughput Satellites(HTS) are satellites with high data throughput, which can exceed 100 Gbit/s and is thus many times higher than that of classic satellites with FSS services.

HTS satellites use multibeam technology and can target specific service zones with spot beams. Multibeam technology has the advantage of frequency reuse, because several beams can simultaneously cover different service areas with satellite signals using the same frequency. The situation is different with FSS satellites, which operate with a small number of beams whose coverage areas can cover entire continents. The frequency reuse and spot beam technology of HTS.satellites, which uses multiple tightly clustered spot beams, have contributed to significant increases in capacity and to the high data throughput. Thanks to the high data rates and large system capacity, many broadband services can be delivered via HTS satellites.

While in the past HTS satellites were mainly used in geostationary positions, they are now also used in geosynchronous MEO satell ites and LEO satellites because of the much shorter delay times.

The further development of HTS technology is called Very High Throughput Satellite (vHTS). It enables data rates of up to 500 Gbit/s.
