Combined Positioning Algorithm and Accuracy Analysis forBD2/GPS Positioning System abstract
To restrain the error sources, namely ionospheric delay andtropospheric delay, in the solution method of BD2/GPScombined positioning system, we introduce the Klobuchar modeland Hopfield model to correct them. By simulating and testingthe real data practically, the result indicates that ionosphericdelay can be significantly decreased with the model. However, itis impossible to eliminate the tropospheric delay. Through usingsatellite selection algorithm for Multi-system, the satellite datawhich elevation of the satellite is less than 10 degrees can beprecluded effectively, which makes it possible for furtherimprovement in positioning accuracy
