Correction of misquoting, but does not affect the conclusion.The landing accuracy of Shenzhou-13 is very impressive.

We can see from the screen capture how close it is. I guess the final touch down point is around 200 meters to the 1st prediction.
- The helicopter was overhead when Shenzhou-13 touched down. Meaning the last prediction (4th) is very accurate.
- The landing range was set in a 3.6km by 3.6km square.
- The 1st prediction was "100 04 46 E, 41 37 23 N". It was made just after seperation of capsule and propulsion module while at altitude between 100km and 140km.
- The 4th (last) prediction was "100 04 34 E, 41 37 23 N". It was made when the capsule altitude was few hundred meters. At this moment it is only 280 meters from the theorotical landing point (1st prediction?).
In comparison, I watched SpaceX's landing on May 2nd. The touch down point was 4.6 nautical miles (8.52km) in range (from the target/prediction).
The local weathers are equally calm.
Smart move which makes the various satellites last longer and without the tremendous costs to loft another replacement.More details on that "service spacecraft" concept by the 8th academy of CASC. I'm not sure how far along this project is. It's basically a refueler for satellites. It performs a soft capture of a satellite and then tops up its propellant tanks.
