摘要：Global navigation satellite system (GNSS) positioning in den urban areas remains a challenge due to the signal reflection by buildings, namely multipath and non-line-of-sight (NLOS) reception. The effects degrade the performance of low-cost GNSS receivers such as in tho smartphones. An effective three-dimensional (3D) mapping aided GNSS positioning method is propod to correct the N

The measurements of the direct and reflected signals can thus be simulated and further ud to determine the ur's position bad on the measurement likelihood between real measurements. Verified with real experiments, the propod algorithm is able to reduce the computational load
