| Abstract: | The basic principle of combined GPS/GLONASS single-point positioning was introduced and the key technical points were analyzed.Then the differences between the 4th order RK method and 8th order RK method was compared.The reasonable determination of the weights for two kinds of observations were researched,computed an actual example to get the practical positioning accuracy and drew some conclusions. |
| Keywords: | combined GPS/GLONASS single-point positioning Runge-Kutta Helmert variance component estimation |
