Shiron Satellite Communications provides broadband satellite communications services using their proprietary InterSKY system. The system utilizes advanced bidirectional ACM technology and Dynamic BM-FDMA to efficiently manage satellite resources and provide high availability connectivity. A case study on a project in Brazil demonstrated how Shiron's solution uses 16APSK modulation for the outbound and 8PSK modulation with ACM for the inbound to balance satellite power and bandwidth usage while meeting a 99% availability requirement across 5917 sites.
