Abstract: The network-based GPS technique provides a broad Spectrum of corrections for real-time kinematic. And the atmospheric refraction error is the main factors to be sufficient to support the ambiguity resolution (AR) and accuracy of the long-distance RTK.However, due to the strong spatial correlated of the tropospheric delay, the elevation difference between the reference plane and the rove station will cause the deviation of tropospheric error in the system so that the accuracy of troposphere correction will be l… Show more

“…The cause of this difference in the Up component may be due to the effect of the Troposphere. As it is strongly correlated with the altitude (Lei et al, 2010), the tropospheric delay predominately affects the vertical component. For short baselines with small elevation differences, the tropospheric delay is very similar on both ends of a baseline and the corresponding bias can be reduced by double differencing of the observations.…”

“…However, the positioning accuracy, mainly determined by the GNSS signal quality and the quality of the GNSS receiver, is still a challenge to restrict the performance of GNSS. The performance of smartphone positioning is significantly affected by these factors, such as the receiver sensibility of GNSS chip [1], the ionospheric delay [2], the tropospheric delay [3], the clock bias [4], the multipath interference [5] [6], and so on. Currently, improving the positioning accuracy of smartphone mainly depends on using high-quality GNSS chips.…”

“…In diversified fields of engineering, the artificial neural network (ANN) has been utilized. ANN applications in geodetic, cartographic, and surveying applications have increased in the last decade and remarkable accomplishments were obtained through ANNs such as: deformation analysis [13], outlier detection in geodetic networks [14], ambiguity resolution for GNSS [15], coordinate-datum transformation [16,17], local geoid modelling [18], georeferencing of historical maps [19], prediction of the Earth orientation parameters [20], geodetic velocity estimation [21].…”
