Abstract
By using satellite surveillance dilution of precision (SSDOP) as fitness function, an amplification method is proposed to optimize the reference stations distribution in the mainland of China. According to the curve of SSDOP changing with stations number, seventeen reference stations are needed in China. The locations of these seventeen stations are obtained by the amplification method. Experiments are made to verify the performance of SBAS with this stations distribution. The horizontal positioning accuracy is 2.77 m, the vertical positioning accuracy is 0.88 m, and the availability is better than 99%. These three indicators satisfy the requirements of CAT I.
