Abstract The release of raw global navigation satellite system (GNSS) observations by Google Android makes high-precision positioning possible with low-cost smart devices. This study contributes to this research trend constructing a stochastic model based on GNSS observation characteristics from smartphones and verifying the feasibility smartphone-based ambiguity fixing in short-baseline real-time kinematic (RTK) case. uses standard deviations (ROSTDs) delivered application programming...
Abstract The precise point positioning real-time kinematic (PPP-RTK) is a high-precision global navigation satellite system (GNSS) technique that combines the advantages of wide-area coverage in (PPP) and rapid convergence (RTK). However, PPP-RTK still limited by precision slant ionospheric delays tropospheric zenith wet delay (ZWD), which affects network parameters estimation user performance. present study aims to construct model augmented with priori ZWD values derived from forecast (GFS)...
To ensure higher productivity, fertilizers have been excessively applied to the fruit greenhouse soil yearly, thus resulting in increasing risks of residual nitrate leaching North China Plain.
