Users get unexpected position information with errors because of satellite clock, ionospheric delay, tropospheric delay and hot noise. Especially if there are crowded many buildings and tall buildings in a small area, larger errors are generated by multi path, reflection and refraction. Therefore, in this paper, we have proposed a post-processing algorithm based on Minimum distance maintenance, Bounce cancellation and Direction vector scheme considering distribution and direction of received position information. Through the experimental results of this paper, we have shown a low average error 5.87m compared to the GPS point positioning that shows an average error 23.4m.
