Positioning Application: Why are pseudoranges different between GPS and BeiDou Geodetic Models?

  • Positioning Application
  • Switching between GPS and BeiDou Geodetic models
  1. The gravitational constant is slightly different between the GPS WGS-84 model and China Co-ordinate system 2000 (CGCS2000) therefore the trajectory will be different
  2. The earth's rotation is subtly different between the two models
    • This means the longitude of ascending node is different, meaning the relative positioning on earth will be different
