摘要

冷原子干涉仪是获得高灵敏度、高精度绝对重力仪的一种很有前途的技术。借助异常重力图，局部重力测量可以实现基于地形的导航。我们描述了绝对重力测量的模型。我们开发了一种基于拉普拉斯的粒子滤波器来适应这种情况。该非线性滤波器能够估计载体(船舶)的位置和速度。给出了在真实模拟数据上的一些结果。

Absolute gravimeter for terrain-aided navigation

Cold atom interferometer is a promising technology to obtain a highly sensitive and accurate absolute gravimeter. With the help of an anomalies gravity map, local measurements of gravity allow a terrain-based navigation. We describe the model of the absolute gravity measurement. We develop a Laplace-based particle filter adapted to this context. This non-linear filter is able to estimate the positions and velocities of a carrier (vessel). Some results on realistic simulated data are presented.
