After entering the atmosphere, the re-entry satellite adopts the full trajectory return mode (without control), so the accurate trajectory calculation directly affects the accuracy of the landing point of the re-entry capsule.
In addition, in order to ensure that the landing speed of the re-entry capsule is not too large, the parachute design and the opening height and way of the parachute are also crucial.
