cost of customizing each ground station system for each different Satellite band is too high. Therefore, various ground station solutions have been designed one after another.
processing part of the SDR-based Ground operations architecture can use a more powerful GPP or a VM/Private cloud of GPPs to realize a full software-defined TT&C ground station. SDR-based Satellite Ground Operations Architecture
advanced solution for the “Signal Processing Component” part of SDR-based satellite ground stations currently uses VNF. SDR-based Satellite Ground Operations Architecture Signal Processing Component However, Cloud-Native Architecture has become a Future Trend.
