Abstract: The GPS/GLONASS dual navigation system increases the number of visible satellites(there are at least 9 satellites visible, ｏｒ an average of 14, up more than 20 anywhere in the world), and make the geometry graphics of the satellite better, then improve the positioning accuracy and satellite navigation capabilities. Therefore, The GPS/GLONASS integrated positioning will have a broad application prospects.
