Abstract: | In view of the characteristics of short distance between reference points,high consistency of the points and high accuracy requisition of the accurate base-line for rocket sled test track,the positioning errors of short GPS baseline were analysed.And then,the measurement precision,coordinate datum,net configuration,observation and data processing method were designed,and uracy anaysis of the measurement results was done.The results show that,GPS relative positioning technology is an accurate and effective method for high accuracy baseline. |
