Reach a safe near hold in front of the target spacecraft, keep the target observable during the approach, then stop and call terminate_navigation(...) when the final target-surface distance is about 2 meters.
Navigation Strategy
- Start from the best currently available geometry source.
- If the
[Sensor] LiDAR block shows points, prefer its distance reading for coarse guidance at longer range and for final surface-distance checks.
- If no LiDAR data is available (vision_only profile), infer progress from target size, centering, visibility, and staged re-observation.
- When distance is measured reliably or can be estimated consistently, prefer forward step magnitudes around 20% of the current distance unless safety requires smaller motion.
- Do not keep repeating the same cached step size for many moves without refreshing state.
- At long range, one or two consecutive translations without re-sensing are acceptable if the target remains well centered.
- Inside about 3m, require a fresh check before further translation.
Completion
- The mission is complete only when the target is still in front and the final target-surface distance is about 2 meters.
