GPS, Satellite Visibility


The novel scheme is proposed and demonstrated where satellite visibility viewed from running vehicle is economically and effectively evaluated with such low cost GPS receivers like equipped in automobiles. The preliminary experiment articulated even economical L1 C/A 1575.42MHz GPS receivers can create enough precise database of ground feature blockage, compared to fisheye photograph method, if only two statistical parameters that this research proposes are adequately set.
