PARTICLE FILTERING AND NAVIGATION SYSTEM USING MEASUREMENT CORRELATION

摘要

The invention relates to a box-regularised particle filtering process which includes an Epanechnikov kernel smoothing step. For this purpose, the process uses a special method for generating random numbers that follow an Epanechnikov probability density function. The process can be performed autonomously in a navigation system using correlation measurement (10), in particular on board an aircraft (20) such as an aircraft, a flying drone or any self-propelled aerial carrier.
