What is a high throughput satellite (HTS)?

HTS dramatically increases bandwidth capacity through frequency reuse. This means that each individual satellite can offer drastically increased bandwidth, and effectively deliver higher performance capability at a lower cost since the cost per bit goes down as more bits of information can be delivered simultaneously.

When organizations like the military or other government agencies start to get more bandwidth, they find new and exciting applications that take advantage of it. For example, when more bandwidth becomes available, GEOINT evolves from blurry photos of the battlefield and troop movements to real-time video surveillance and enormous, interactive maps. Communications evolves from voice to 4K video teleconferencing. Information sharing evolves from pre and post-operation briefings to the ability to access digital information from anywhere on any device.



SES High Throughput Satellites (HTS) at Geosynchronous Orbit

Our addition of three next-generation satellites to its family- SES-12, SES-14, SES-15 and GovSat-1, will allow SES GS to address the accelerating needs of new government video and data applications and provide significant high-power capacity for faster and more enhanced video and data for both stationary and comms-on-the-move missions. All three satellites, manufactured by Airbus Space and Defence, Boeing and Orbital AKT, respectively, will be using the newest spacecraft technologies, leading to optimal performance and highest efficiency.

SES-14 and SES-15 are both powerful hybrid satellites, using Ku-, Ka- and — in the case of SES-14 — also C-band in wide-beam and high-throughput technology and a purely electric propulsion system that significantly enhances the satellites’ economic efficiency thanks to the enhanced payload that can be carried as a result of the reduction in fuel mass.
