Fast Satellite Ground Synchronization Technology Advances Beam Hopping Communications

Researchers from Xidian University, CAST-Xi'an Institute of Space Radio Technology, Beijing Institute of Technology, and the Global Big Data Technologies Centre at University of Technology Sydney have analyzed the requirements for synchronizing satellite beam hopping with ground signal stations to enhance high-throughput satellite (HTS) communication capacity.

HTS systems use multibeam technology to overlap service area coverage and multiple frequency multiplexing to increase satellite link capacity. Gateway stations are closely integrated with user beam clusters for efficient, two-hop communication via shared satellite resources, allowing spatial isolation and frequency re-use.
