Separate real antenna motion from apparent base motion. Measure the lever arm, record a controlled rotation, and verify the deployed compensation path with common-time evidence.

Verify heading inputs before changing an offset. Compare cardinal-direction observations, raw fixes, effective navsat parameters and the geographic-to-map frame relationship.
