Which MSSR subsystem is used for health monitoring and maintenance tasks?

• A. CMS (Control and Monitoring System)
• B. Plot Processor
• C. Transmitter Interface
• D. Receiver Interface

Answer: (A)

Health monitoring and maintenance tasks in MSSR are handled by the Control and Monitoring System. This subsystem serves as the central hub for the radar, continuously checking the status of all components, collecting telemetry, logging faults, raising alarms, and coordinating maintenance actions like software updates or remote resets. By integrating status information from the transmitter path, receiver path, and processing blocks, it provides diagnostics and maintenance control across the entire system, helping keep the MSSR healthy and available.

The Plot Processor is focused on data handling and display of track information, not on system health or maintenance. The Transmitter Interface and Receiver Interface manage the hardware interfaces to their respective RF paths, handling signal flow and control at those interfaces rather than broad health monitoring or maintenance tasks.
