High Throughput Satellites (HTS), also known as high-capacity communication satellites, differ from traditional communication satellites in their use of the same frequency resources. Key technical features include multi-spot beams, frequency reuse, and high beam gain.

        HTS can provide several times to tens of times more capacity than conventional communication satellites. Conventional communication satellites have capacities of less than 10 gigabits per second (Gbit/s), while HTS capacities can range from tens of Gbit/s to over a hundred Gbit/s. Classified by orbit, HTS satellites include geostationary orbit (GEO) and non-geostationary orbit types, with GEO satellites currently dominating in-orbit applications.

        China's current projects in this area are actively advancing in conjunction with the National Integrated Space-Ground Information Network project and the Belt and Road Initiative Space Information Corridor project. Once completed, these systems can establish broadband satellite information systems aimed at key regions while serving global needs, supporting strategic initiatives such as the Belt and Road Initiative.
