An Approach to Speed up Single-Frequency PPP Convergence with Quad-Constellation GNSS and GIM
The single-frequency precise point positioning (PPP) technique has attracted increasing attention due to its high accuracy and low cost. However, a very long convergence time, normally a few hours, is required in order to achieve a positioning accuracy level of a few centimeters. In this study, an a...
