Abstract：In according to the positioning principle,the article discusses BDS positioning accuracy from the accuracy of time and space,and comprehensively analyses the effect on accuracy of satellites'orbit,atomic clocks,ionospheric delay,multipath ef?fect and so on four aspects on single BD machine positioning ,then corresponding measures are puts forward to improve the position?ing accuracy. Finally,there is a brief introduction about the auxiliary differential enhancement system which can greatly improve the positioning precision.
