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[1]) for the same amount of allocated orbital spectrum, thus significantly reducing cost-per-bit.[2] ViaSat-1 and EchoStar XVII (also known as Jupiter-1[3]) do provide more than 100 Gbit/s of capacity, which is more than 100 times the capacity offered by a conventional FSS satellite.[4] 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.[5]
