The system consists of a coordinator, a timekeeper, and three satellites communicating with ground stations through synchronized channels.\n\n\u003e This repository was created for a university assignment on formal modeling and verification.\n\n## What the Model Includes\n- Time-slot based scheduling of satellite transmissions  \n- Blocking synchronous communication (`!` / `?`)  \n- Per-satellite message buffers  \n- Coordinator logic for granting channel access  \n- LTL properties for safety, liveness, and fairness\n\n## Verified Properties\n- Mutual exclusion of slot grants  \n- Eventual processing of satellite buffers  \n- Fairness: each satellite is granted access infinitely often  \n- Deadlock freedom\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Filovebacteria%2Fsatellite-communication-model","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Filovebacteria%2Fsatellite-communication-model","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Filovebacteria%2Fsatellite-communication-model/lists"}
