AI Technical Summary

Technical Problem

Existing satellite payload architectures for VHTS and HTS applications are inflexible, leading to overdimensioning, frequency coordination issues, and inefficient use of transmission resources, with limited capability to adapt to varying traffic demands and requiring multiple access stations.

Method used

A flexible payload architecture utilizing a digital transparent processor and beam hopping operation, combined with passive multibeam antennas, allowing dynamic allocation of transmission capacity and connectivity between user spots and access stations, while minimizing the number of access stations and avoiding frequency coordination problems.

Benefits of technology

The solution provides a lightweight, low-complexity payload that can dynamically allocate transmission capacity to meet varying traffic demands, rationalize access stations, and ensure each user spot accesses the full available band, while supporting mesh connections without ground relays.

Abstract

A VHTS or HTS multibeam telecommunications payload is provided, comprising a first multibeam antenna system (204) with passive antennas, configured to receive from and transmit to spots of access stations GW respectively in a first satellite receive Rx band and a first satellite transmit Tx band, and a second multibeam antenna system (206) with passive antennas, configured to receive from and transmit to a user coverage zone respectively in a second satellite receive Rx band and a second satellite transmit Tx band, by generating multiple satellite receive user spots and multiple satellite transmit user spots. The payload comprises a digital core (210), based on a digital transparent processor DTP (212) offering total connectivity and total flexibility of allocation of frequency slots to the access station and user spots.
