The derivation of path following error and control motion noise filters for the reduction of Global Positioning System flight test data

Abstract

In order to perform a complete comparison with existing systems and properly define and analyze the error properties of the GPS (Global Positioning System), PFE (path following error), and CMN (control motion noise) filters need to be defined for use during testing activities. The author discusses PFE and CMN characteristics and how these error components affect flight and aircraft systems, and then derives digital filters that can be used to reduce GPS data into components of PFE and CMN based on international specifications.<>
