Satellite communications upgrades focus on higher throughput links, better scheduling, and improved resilience for mission operations. The stack now supports configurable quality‑of‑service so operators can prioritize critical telemetry and science data during limited passes. Scheduling algorithms and interfaces were refined to coordinate across multiple satellites and ground stations. Security and authentication standards were reviewed and strengthened where needed. The program includes comprehensive testing: simulated link conditions, fault injections, and dry runs of incident playbooks to verify that improvements carry through under stress. Documentation details how to deploy and operate the stack, with an emphasis on transparency and repeatability. Future iterations will assess optical pilots and cross‑support arrangements to further expand capability without compromising safety or reliability.
