Abstract：The focus for the optimal design of GPS observation scheme before GPS control network should be built is on two issues including GPS observation time and receiver working conditions. The testing data show that it is importance to choose observation time and GPS receiver for the network quality control. The results of practical observation prove that when the surveying range is longer than 10 km, the accuracy of the solved result of observations in night is higher than that in day,when the range is several km or over ten km,the accuracy observed with receiver of single frequence is higher than that with the receiver of dual frequence.
