Mapping the spatio-temporal visibility of global navigation satellites in the urban road areas based on panoramic imagery

The satellite visibility number of GNSS is an important indicator for evaluating its availability for positioning and navigation. In urban areas, urban canyons cause serious satellite signals block, resulting in positioning uncertainty. Many studies used 3D city models to evaluate the visible satell...
