Novel algorithms for GPS network RTK   总被引:1,自引:0,他引:1  
This paper gives some new algorithms for GPS Network RTK. The whole algorithms are based on the Double-Difference (DD) using single epoch of GPSdata. So cycle-slips and loss-of-locks of GPS satelliteare avoided. And the time of Network RTK systems tart-up and positioning is shortest, only one epoch.These algorithms need no ionospheric or troposhperic correction models. The combined bias of rover station is directly estimated and corrected by observations of reference stations of network. Hence, the algorithms are no delay, and are the really and truly real-time difference and positioning. Compared with other algorithms, they can synchronously eliminate orbital bias, ionosphere delay, troposphere delay and otherbiases of positioning correlated with distance to great degree. There are little residual high order biases and measurement noise in DD observation equation of rover station after difference correction, so RTK positioning of network with the algorithms can perform wider and more equably.  相似文献
