To restrain the error sources, namely ionospheric delay and tropospheric delay, in the solution method of BD2/GPS combined positioning system, we introduce the Klobuchar model and Hopfield model to correct them. By simulating and testing the real data practically, the result indicates that ionospheric delay can be significantly decreased with the model. However, it is impossible to eliminate the tropospheric delay. Through using satellite selection algorithm for Multi-system, the satellite data… CONTINUE READING
