gps导航工具包,可用于分析GPS误差,伪距及导航融合算法(This report include the review of
Principle of Radio Navigation: navigation base on trilateration has been investigated and the over determined Eq. for navigation has been solved.
GPS Ephemeris Data: for GPS navigation, the position of GPS satellite is very important so the by receiving ephemeris data the position of the satellite is determined.
GPS Errors: Three different sources of errors in GPS navigation has been investigated (Ionosphere, Troposphere and Satellite clock). Ionospheric Error model is generated base on Parkinson [1] and the Tropospheric Error Model based on Hopfiel model [2].
Simulation & GPS Toolbox: One of the targets of this work is generating Matlab GPS Toolbox and in one case study the performance of generated toolbox will be verified.)
