| Abstract: | During the total eclipse on July 22,2009,the authors monitored single-frequency GPS signals in Qingdao through fixed-points.The signals were compared with those in non-eclipse period.The result showed that the partial eclipse in Qingdao had effects on the navigation and positioning accuracy of single-frequency GPS receiver system,such as increasing error,decreasing number of satellites received and increasing PDOP values.In short-term,the maximum deviation of the position is 4.02m,which lasted 2 minutes and 48 seconds.However,in Qingdao,the partial eclipse which lasted only a short time has little effect on GPS accuracy,and the same as the low-precision marine survey navigation data accuracy.Therefore high-quality navigation data was required to make comparison and correction with GPS data obtained from synchronization shore station. |
