地形辅助导航系统的关键技术

Key Technologies of Terrain Aided Navigation System

地形辅助导航系统被誉为第四代导航系统 ,除了计算机技术外 ,注重讨论了在地形导航系统中利用的数字地图技术、存储技术、地形随机化技术、多模卡尔曼滤波技术和数字相关器 ,对各技术的特点及其有关的参数进行了分析。

Terrain Aided Navigation System(TANS) is regarded as the forth generation navigation system. This paper mainly discusses the key technologies used in TANS expect computer technology: digital map, data memory, terrain randomization, parellel Kalman filtering and numeric correlator and their characteristics and related parameters is also analyzed.
