Comprehensive Overview of GDS Spacecraft Communication Protocols and Frameworks

This document provides an in-depth exploration of the GDS spacecraft communication systems, focusing on various protocols and frameworks utilized in the VxWorks and Linux environments. Topics include RAMS gateways, SMC controllers, DGR message queues, and UDP/TCP communication. The integration of different operating systems such as Solaris and Cygwin is analyzed in relation to their respective roles in spacecraft operations. Additionally, the report discusses reliability through the SPOF classification and the implementation of firewalls in interplanetary communications.
