GPS Toolbox matlab

 include • 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.
