| Abstract: | The underwater users of PNT system are classified. The gap been requirements of underwater users and the current underwater PNT system is analyzed. The construction conditions of underwater PNT system and the construction plans of some countries are studied. On this basis, the development direction of underwater PNT system is analyzed. Finally, in view of the characteristics of underwater PNT system, key technologies such as inertial technology, gravity/ geomagnetic matching technology, acoustic navigation technology and evaluation technology are introduced |
