| Abstract: | Multipath effect is one of the main errors that affect the positioning accuracy of satellite navigation receiver. Aiming at multipath modeling, firstly, property of static multipath is analyzed, parameters that influence multipath are extracted, and correlation relationship between them is established. Then, segmented spherical harmonic and segmented trigonometric series function model of multipath are constructed, and the precision and complexity of these two models are compared. The result shows that segmented constructing multipath model using trigonometric series model and spherical harmonic function model is feasible and the former is better than the latter. |
| Keywords: | multipath simulation and modeling GNSS system spherical harmonic function trigonometric series function |
