🔍 Key Concepts

• Stabilized satellite antennas use motors and sensor inputs (like heading, pitch, and roll) to keep locked on the satellite • Antenna initialization sets a reference; continuous azimuth hunting usually points to an issue with reference data or feedback, not vertical (elevation) motion alone • Distinguish between diagnostic steps (software/log checks) and physical component checks (motors, cables, sensors)

💭 Think About

• If the antenna keeps rotating in azimuth after it has already initialized, what basic information does it need and possibly be missing or corrupted? • Which option is the safest, least invasive first step that could confirm or rule out multiple potential faults without immediately replacing or opening hardware? • Think about whether the symptom points more to elevation control, azimuth control, or data/feedback going to the controller

✅ Before You Answer

• Identify which option allows you to see recorded faults or error codes related to tracking problems • Ask which choices involve unpowered inspection versus powered operation and control data review • Eliminate any option that targets a component (e.g., EL motor) that does not directly explain a pure azimuth tracking instability right after initialization
