在SUH的定点降落中，飞控系统需要实时且高精度的相对位置信息，特别是离地高度信息，而传统INS/GPS组合导航配合声纳高度计并不能满足要求。
During the spot landing stage , the flight control system requires real-time and high precision relative location information , especially the height information . However , INS / GPS integrated navigation with the sonar altimeter can hardly meet the requirements .
